Time Stamps (ET):
 +
 +
17:06 - introductions, etc. coming off of the meeting, we have a chance to restructure. Martha Apple is transitioning out as is Scotty. Sent invites to some folks to discuss co chairing. Idea of hands-on sensor building, cluster focused toward that end (interactive building).
 +
 +
17:08 - summer meeting recap. Even though it was a back up it went very well, was useful for figuring out the scale of tinkering that is possible given the time constraints.
 +
 +
17:11 - John P. more show and tell than planned. Good show and tell, though! Good range of people, a relative novice to experienced users. A question to throw out. What is the audience were trying to reach and what do we want them to learn?
 +
 +
17:12 - Joe, looking ahead, have use cases etc. We can have a suite of parameters (temp, pressure, etc) HydroTech, Grad Student, Researcher, environmental consultant. When i collect this data, how am i collecting this data to share? Use cases Joe would seek are: good data quality, collection, and delivery. Do we get this out through a GS database or something like coords.
 +
 +
17:14 - James G. What do we think of as graduate students and their capabilities? Where do they start? Have they had python experience? Only informal?
 +
 +
17:16 - Dan Fuka, are we not trying to hit a slightly lower layer on the technology stack? Actually getting or creating or having a device they can work through to familiarize themselves with data flow. I.e. how do you pass info between devices, etc. Thats the hardest layer to get people started themselves. As we know, each of these layers is fairly complex, programming the arduino etc, using amazon cloud services or other data repositories. How do we get value off of a specific sensor? A workshop towards that initial introduction, not focused on a new set of people, but those focused on ESIP returners and the faithful. Allows folks to start on the same page (those that attend the meetings with frequency)
 +
 +
17:18 - Scotty: there is the "intro" crowd, i.e., people that know something about using software and basic scripting/programming....and then there is a "technical" crowd that has some combination of DC electronics, mechanical/fabrication, database, software backend, wireless, etc. experience
 +
 +
17:19 - John P. many permutations of sensor data/communication. Lot of options out there for networking, what is great is to see some working solutions and say “hey thats like my problem”. John took a course that had standardized hardware etc, was all planned out. Towards the notion of training within ourselves. Having some sessions where folks go into some depth about their own solutions or works in progress. Could be more of an office hours.
 +
 +
17:22 - Joe: needs for use cases. The organization chooses a single source/product is great. This is where to build off the prev session. Using the USDA board. The winter meeting could be use cases, talks, urban vs forest etc. Each session would have a focus of honing the use case, and working with the core group.
 +
 +
17:25 - John P. would love to play around with daniels board. Important to have one that works and is accessible to people. But its easier to build with success, aka using the usda board.
 +
 +
17:25 - As scotty steps back, cluster has the opportunity to move forward etc. as such, we need to discuss the audience. There is the internal audience (highly skilled, technical people) then there is the external audience (all others, stakeholders etc). They have questions regarding using/deploying sensors. Do we do a demonstration with those external audience members. Can we touch both audiences?
 +
 +
17:30 - Megan C. you have to start with who is showing up now, what do they need. Who is not here that we would like to see here. The faithful etc. But there is the grad student/general ESIP population. Could work across committees.
 +
 +
17:32 Joe, what does the cluster provide now? Site selection, planning data routing, the specific use cases. The grad student that Joe thinks of is one who is focused on sensors etc. maybe we can be a place. Simple build experiment and provide the instruction. And where do I send my data?
 +
 +
17:34 Dan Fuka: wrapping thoughts together, maybe we need some grad students to pull into this.
 +
 +
17:36 - James G: don’t really think the problems associated with the boards and the sensors are not unique to what were looking at. There are 1000s of links associated with that sort of stuff. We have always looked at the big picture. There is another technical problem though, you have sensors in the field, how do you get those data out of the sensors and into a place that is visible? This is the part of the use case where we can go where others cant go.
 +
 +
17:39 - Joe: Q to James, what would we then orient to? 2 ways: go to device and get the data (doesnt really address the problem) Coords and thingspeak/ iot things might be more amenable. Data management, provenance, archiving, etc. are there repositories for those info? Becomes a complicated problem. As the sensor networks we deploy grow larger, the data processing and managing gets more difficult.
 +
 +
17:41 - Dan Fuka - after our group has common knowledge we can utilize, then we involve others (other esip clusters etc). Lets get our problem to the point where the data is transmitting. Then we can decide on how to move forward. Maybe DataVerse?
 +
 +
17:42 -  Scotty: Thinking out loud here......gonna be difficult to address the full spectrum of problems across the workflow....in a monthly 1-hr cluster....the 2014 assembly of best practices was high-level and it still took forever.....
 +
 +
You may be more successful with some deliverables by really being focused on 1-2 parts of the workflow....and saving the wider discussion for an annual event?
 +
 +
17:43 - James G. responding to Dan, not sure we have the time for that. May have to accept its gonna be messy and go forward on all fronts.
 +
 +
17:44 - Joe, what if we took an more “ESIP” view. We can to connect with this cluster (hazards life cycle) set that as the scope for the sensor we build. Could let them choose the data handoff. That approach may provide a filter we need.
 +
 +
17:47 - Scotty: Joseph needs to recruit folks to put time in etc.
 +
 +
17:50 - Megan: this makes a strong case for a broader event (annual event) sticky spots etc. talking more broadly, where were going to focus in the near term, but starting with a broader enticement to ESIP.
 +
 +
17:52 - Joe, we have 2 different vectors.
 +
 +
17:53 - formalizing a build, then purchasing the build and what practices etc.
 +
 +
17:54 - Dan Fuka, there are methods out there for how to sense many many things and get the data, start collecting, etc. how to get it into a few repositories. Predominantly commercial. The only problem I have is how to get that into an open data repository. Have had problems with this for years. Where do we put the data? How do we get it to the world?
 +
 +
17:55 Megan I need to go now. Sounds like there are a lot of good ideas. Just remember everything will take longer than you think in terms of planning. Be kind to yourself in setting milestones. Make sure to build in what you each need to get out of this group and the ability to pivot and make adjustments along the way.
 +
 +
17:56 - John P. there are solutions (lightweight ones) in the ecological space. EDI (<nowiki>https://edirepository.org/</nowiki>)  is where LTER is sending its data these days. But they are open to others, DataOne is similar and related. Etc. <nowiki>https://knb.ecoinformatics.org/</nowiki>
 +
 +
17:59 - this is clearly a problem and some people are clearly addressing it. The use case is connecting up the sensors to cloud data archives. Come prepared to talk on these topics.
 +
 +
18:01 - Here is the list of member nodes for dataone. Some of these might work (it includes KNB and EDI): <nowiki>https://www.dataone.org/network/</nowiki>
 +
 +
Do we have people come and talk about that?
 +
 +
18:03 - See also: Globus: <nowiki>https://docs.globus.org/api/</nowiki> (USGS has a license) - David Coyle
 +
 +
18:03 - EasyEML
 +
 +
18:04 - STAC is cool but complex.
 +
 +
18:05 - Globus is an interesting conversation....started out as a transfer tool....
 +
 +
James g. We want to know what is good enough,

Time Stamps (ET):
 +
 +
17:10 - Research watershed in NE Vermont, sleepers watershed
 +
 +
17:11 - Northern VT, near Quebec
 +
 +
17:13 - instream is fluorescence, turbidity, CO2, meteorology, snow measurements
 +
 +
17:14 - “Snow station” sleepers, lot of snow instrumentation. Dont get a deep snow pack, (<1m) make up for it in persistence. 500 m elevation
 +
 +
17:14 - 111 km^2 do most work in the headwater region, about 100 acres
 +
 +
17:15 - lot of snowmelt monitoring, DOC measurements as that is mobilized.
 +
 +
17:15 - absorbance and fluorescence for carbon quality
 +
 +
17:16 - use it to detect organic carbon molecules (only 2-3% fluoresce, but the measurement is so precise that it is a useful proxy.
 +
 +
17:17 - fluorometer and turbidity sensor + CO2 sensor. In the water.
 +
 +
17:18 - FDOM (proxy for DOC from fluorescence) shows that DOC is highly flow dependent.
 +
 +
17:19 - mirrors discharge quite well (DOC), however nitrate peaks with peak flow, and then relaxes, once per year or so
 +
 +
17:21 - Turbidity is an SSC proxy
 +
 +
17:22 - Consistent relationship between % of DOC that is part of SSC
 +
 +
17:23 - turbidity corrects FDOM signal as the signal is dragged down by high turbidity (sensor is only seeing half of the FDOM)
 +
 +
17:24 - DOM dissolved organic (material?) is colored dark orange, the question is does it go to the stream
 +
 +
17:27 - UVM Snow project, Whiteface to Mt. Washington: New York, Vermont, New Hampshire
 +
 +
17:28 - 22 sites across the network, 3 at sleepers river
 +
 +
17:29 - cadillac of the operation is the Somers Snowpack Analyzer, uses the dielectric constant to calculate the impedance of the snowpack, determining the amount of ice, air and water in the snow pack which add up to 100%. Pretty sweet. Can go up to 3-4 m plus. Has an angled sensor that integrates over the depth of the snowpack. Can determine when the snowpack might release. The Somers Snow Scale is also used (maybe more familiar with the snow pillow), the scale is only in the very center of a 2.5 m^2 unit.
 +
 +
17:32 - Water Quality monitoring, Lake Champlain
 +
 +
17:33 - Buoys are lowering down FDOM and turbidity sensors, plus temp, conductivity. Attempting to track the thermocline
 +
 +
17:34 - Burlington is on the shores of lake champlain
 +
 +
17:34 - Question from James about Somers Snow Sensor, sounds like how moisture sensors are sensed.
 +
 +
17:36 - Martha: could be useful for late into summer ice packs (like in the rockies)
 +
 +
17:37 - SNO(W)TEL (sp?) lot of universities are lobbying congress to fund a version in the east
 +
 +
17:40 - Dan asks about neutron probes–for soil moisture, or for any moisture

17:17 - Presentation begins
 +
 +
Passion project that was developed within the USGS. Will be presenting at association of floodplain managers next week
 +
 +
17:18 map is alternative way of delivering USGS stream gage data. An integrative approach
 +
 +
17:19 idea came as an end user of USGS stream gage data. Stage height data is not very intuitive.
 +
 +
17:21 - gage height in relationship to nearby structures or locations, bridges, parking lots, etc.
 +
 +
17:22 required to survey them once every 3 years. So would be easy enough to measure elevation up to close. Flood impact locations are shown with icons that indicate flooding.
 +
 +
17:25: can receive alerts if nearby locations are flooding, can also look thru historical data.
 +
 +
17:27 Accessible to the end user.
 +
 +
17:34 Intuitive interface
 +
 +
17:50 would be useful to get remote sensing data.

17:15 - absorbance and fluorescence for carbon quality

17:16 - use it to detect organic carbon molecules (only 2-3% fluoresce, but the measurement is so precise that it is a useful proxy.

17:17 - fluorometer and turbidity sensor + CO2 sensor. In the water.

17:18 - FDOM (proxy for DOC from fluorescence) shows that DOC is highly flow dependent.

17:19 - mirrors discharge quite well (DOC), however nitrate peaks with peak flow, and then relaxes, once per year or so

17:21 - Turbidity is an SSC proxy

17:22 - Consistent relationship between % of DOC that is part of SSC

17:23 - turbidity corrects FDOM signal as the signal is dragged down by high turbidity (sensor is only seeing half of the FDOM)

17:24 - DOM dissolved organic (material?) is colored dark orange, the question is does it go to the stream

17:27 - UVM Snow project, Whiteface to Mt. Washington: New York, Vermont, New Hampshire

17:28 - 22 sites across the network, 3 at sleepers river

17:29 - cadillac of the operation is the Somers Snowpack Analyzer, uses the dielectric constant to calculate the impedance of the snowpack, determining the amount of ice, air and water in the snow pack which add up to 100%. Pretty sweet. Can go up to 3-4 m plus. Has an angled sensor that integrates over the depth of the snowpack. Can determine when the snowpack might release. The Somers Snow Scale is also used (maybe more familiar with the snow pillow), the scale is only in the very center of a 2.5 m^2 unit.

17:32 - Water Quality monitoring, Lake Champlain

17:33 - Buoys are lowering down FDOM and turbidity sensors, plus temp, conductivity. Attempting to track the thermocline

17:34 - Burlington is on the shores of lake champlain

17:34 - Question from James about Somers Snow Sensor, sounds like how moisture sensors are sensed.

17:36 - Martha: could be useful for late into summer ice packs (like in the rockies)

17:37 - SNO(W)TEL (sp?) lot of universities are lobbying congress to fund a version in the east

17:40 - Dan asks about neutron probes–for soil moisture, or for any moisture

17:17 - Presentation begins

Passion project that was developed within the USGS. Will be presenting at association of floodplain managers next week

17:18 map is alternative way of delivering USGS stream gage data. An integrative approach

17:19 idea came as an end user of USGS stream gage data. Stage height data is not very intuitive.

17:21 - gage height in relationship to nearby structures or locations, bridges, parking lots, etc.

17:22 required to survey them once every 3 years. So would be easy enough to measure elevation up to close. Flood impact locations are shown with icons that indicate flooding.

17:25: can receive alerts if nearby locations are flooding, can also look thru historical data.

17:27 Accessible to the end user.

17:34 Intuitive interface

17:50 would be useful to get remote sensing data.

Dan Fuka

ARS established partnerships for data innovation in 2019 to shape FAIR habits, partner ship between ag research and private sector tech companies. Microsoft and ESRI joined forces to provide ARS a platform,

ARS provides 90 locations and 137 worksites around USA

USDA-ARS PDI @ Hydraulic Engineering Research Unit (HERU)

$25 Multi Science Station, fun small project for sensing purposes to determine where horses go to the bathroom

Getting into CS screw terminals is a pain

Almost ideal embedded MCU +LoRa low price and saves dev time (saves 16 solder joints)

With NDA Build America, Buy America Act

>60% manufactured in the US.

IoT is great learning tool, several groups have designed IoT based traditional WX stations (3D-PAWS)

Traditional but takes a while to build and install.

Field Techs and Researches have been programming data loggers since the beginning of epoch time!, it seems ok for them. However, mouse driven workflows are a different story.

Kade and Dan then went to SparkFun

Jennifer Mullins:

SparkFun has a good system for a la carte board designs,

SparkFun wants to accelerate prototyping, initiatives, experimenting, etc.

Make technology easily accessible to as many people as possible and strive to find creative solutions to meet users needs. Happy to develop relationships w partners

SparkFun develops original product release once a month, also can do resell which are specifically targeted to support SF initiatives.

Launched a services branch 5 years ago to find creative solutions for customers.

Services:

-Custom Kitting

- Hundreds every year, lot of universities, end use solutions for business partners as well.

-Custom Design (USDA)

-Custom Design, however, constantly busy at this time, but continuing to evolve and expand at this time

-Logistics

-Logistics, will support needs of customers, shipping, inventory management etc.

-Marketing Development

Marketing has been able to support really incredible projects through custom landing pages, creating customized forms, product documentation and tutorials, custom product pages

ALC DESIGN TOOL

-Custom design/ideation

-SparkFun authorized reseller/manufacturer

-US-based manufacturing

ALC provided a jumping off point for engineering.

Design process:

USDA project

-Board development/design with our Engineering team. Constant communication with USDA on spec, adjustments, etc. Final design reviewed and approved to move to prototype then full production.

Production/Manufacturing

Procurement-PCB’s and components are ordered; lead times vary

Scheduling - Build is scheduled

Production - Time depends on complexity and schedule

Testing - we test everything

Inventory & Shipping -we ship globally

The Final Product:

  • Dan:

Very simple to interface with SF, had few meetings but very quickly a design was returned.

  • Dryw
  • Built it, tested, sent it to Kade and Dan for testing,
  • Completely open source project
  • USDA Watershed Monitor

Dan

  • GPS
  • Can go almost a year on the battery, some 16k chirps
  • Supplemental power through solar
  • Looped chirping of gps and WX gives ~12k chirps
  • LowPower - 180uA regardless
  • How to ID these things? For public IoT based sensing, what about getting a mac address block?

Get hands in the units of ESIPers

Is 10 distributed dataloggers the maximum? Say at 10 min intervals

LoRa can go from tip of SA to canada with a yagi (sp?) antenna

Talk to megan re conference details

How much time will this take?

  • Possibility of starting before lunch so that we took lunches out into the field.
  • Telemetry, LoRa or cell chip?
  • Distributed stations to gateway to internet
  • Several stations (5) and at each station there is a different component of research, by the end, they have a sensor chirping out 5 different data streams.
  • SparkFun is looking to attend ESIP

Time Stamps (ET):

17: - Envirosensing slack channel question

  • Raskin Scholarship
  • Field trip related activities
  • Shriever (sp?) Watershed with in depth temperature records plus others, east side so it would take a little bit to organize a trip out there. Also connecting with folks at a local college that could put on a field trip. Pushing from GS side. Could go from there and launch into ideas. - Joe

17:12 - not a lot of joint monitoring in vermont. There is monitoring by private industry but the USGS footprint in VT in small.

17:13 - Jameson from climate change canada. Sentinel lake.

17:14 - Right next to a wooden glen

17:16 Megan is going up soon so we can give her questions to ask

17:17 Joseph says he is willing to help scout the meeting as well

17:18 Maybe there is potential for two workshops

17:20 Concept of spanning over the lunch time.

17:21 What about starting from morning and going through lunch.

17:22 Last week we talked about a hands on sensor making session where we have arduino kits or something. Would be a good thing to do.

17:23 - Dan, soldering takes time, design he has makes connecting new sensors easy w/ ethernet.

17:24 - Could do drones and sensors together, full workflow would be good. So what do we need to go there

17:26 just need proposal with requested timeslot and paragraph - a combined session

17:27 can call the tower close by and ask them for permission. If they okay it we can fly drones

17:30 workshop on making sensors, then same or different day get deploy sensors

17:31 University of VT has LoRa WAN access can see if we have coverage: sensor folks, what would we look to transmit the data over?

17:32 LoRa 2 LoRa single channel LoRa. We can leave this open.

Bluetooth low energy as a replacement for LoRa. James, just bring a few leaf nodes. How is the way we get data? Joseph can have a LoRa gateway there easily from USGS. The Echo Lake Science center. Classrooms and learning spac could be another resource

We can plan for a specific LoRa , 4 or 5 different frequences that can have uplink. Also open call for folks to bring what they like. Bring an uplink of use ours. We can provide authentication information. Cellular device would you need to check coverage on the nearby towers? –  another exciting thing is the CBRS ESNet presentation from andrew wiedlea, but i dont know if we can get a station ready. But would be cool.

Could also use HAM

David Coyle - solid state circuit breakers and other things are becoming more available at moderate power. Could be able to monitor energy of devices.

We need to figure out what we need to provide, kits would be ideal

Suppose we had a workshop but you have a lab fee, popular arduino kit, can pick ones that dont require soldering. Difficulty is you wont get an IP68 case. You could stick those things in the woods. Could also use little salad containers.

Dan - ESP32 could be a good option. Has many useful features. You can strip an ethernet cable and connect it! Also LoRa, Qwiic, BME680, Load Cell. SparkFun Boards could be cool. Whats cost per board? Would need to find funding.

Could take the ferry from Burlington to New York, there are three now according to Joseph. It takes about 45 minutes.

Field Trip - Remote .. maybe

Field Trip - Local .. looking good, centennial woods, Leahy center for lake champlain (ECHO)

Could also extend it into the evening, have a bar evening or the like.

Megan - Ask to visit Centennial Woods and possibly the Leahy Center, also ask about funding costs, we need to ascertain whether we are doing 1 kit/board per person or groups of people.

Workshop fee? Possibility. 30 dollars for the workshop / 100 for total.

Some of the arduinos come with multimeter and have a bunch of gizmos with em. Servo motors etc, which might be cool for the people.

For every 10 units comes a cellular uplink!

Thing worth throwing out there: cellular uplink could push us in a different direction. Cellular point would be useful…

Dan has an ESRI geoserver, if not esri, there are a lot of IoT things. Its REST based webserver. Also has Coords and ESRI

We should consider the accessibility of the situation as well.

By next meeting in April, we should have a kit refined. Ideally we are demoing it in the april meeting. That will be training for the workshop.

Review of winter meeting  

Allison Mills 5:09 PM

Thanks, folks! Here is the IT&I info: https://esipfed.org/ITI

Registration for the Highlights Webinar: https://www.esipfed.org/get-involved/community-calendar

Sched - all session notes, recordings, and resources live here: https://2023januaryesipmeeting.sched.com/

Not a lot of EnviroSensing at winter meeting…. Opportunities for future meetings

Sessions on New satellites (ops for link to ground data)

In Situ data through cloud providers

Session on fires – sensor applications (possibly with new wildfire cluster)

There might be potential session collaborations with other Clusters for the July Meeting (James just named Cloud Computing and Air Quality and also the new Wildfires)

Fusion of in-situ and remotely sensed data is no-brainer especially if it can help in real time calibration.  Can improve way satellite data is processed - radiation needs to move through the atmosphere twice to reach satellite.   Small number of ground sensors can be spread out.

Allow more depth in field studies.  Shift from pulling to pushing - more cost effective sensors.

Data publication: making it accessible to others – big part of IoT

Price is coming down on sensors, can move toward distributed networks. Dan opines on the cost of sensors and economies of scale. Daniel shifting to more costly sensors - see more next month

Switch to where we’re going:

Discussion:

Around the Room:

Joseph - USGS focus on R&D upcoming. Observing Systems Division involved. Training Certificate being discussed for link to Academia (practical, records processing, fouling and calibration drift adjustments).  Everything from entry level to partial diff equations.  

Q: any travel grants for summer meeting?  ESIP will cover travel for 1 or two speakers… but not USGS.

GS wont sponsor travel, but funding for trips sometimes happen.

Dan - had to spend lot of $$$ in 2 weeks, developed sensor w james and martha, slightly more expensive– $166. ESP32 low power capability, LoRa, BME680 (temp, pressure, rel. Humidity, volatile organic carbon), 9DoF (Wind velocity), Loadcell, Weighing lysimeter

Cellular note carrier (lifetime supply of data Qwick Cellular Notecarrier 500MB), goal is 10 or more sensors which can communicate

All US weather stations combined are ~ 1GB (including history)

USDA funded development of sensor via SparkFun, fed agencies cant buy chinese parts (rip)

ESIP Summer meeting ideas: potential workshop outside, putting together session / tutorial. Possibly a multi-day event. Couple hours plus a lunch w/ workshop afterwards. Outdoor + drones group would be great. Flying around collecting data

Bryan, SparkFun engineering manager. Custom designed unit but started with building blocks–full custom board solution for Dan. Background in implementing wifi connection + bluetooth in small devices like printers. SparkFun is open source and open hardware with a focused on learning/teaching.

All local manufacturing and sourcing within SparkFun

John - Wrestling LoRa, has LoRa gateway set up on eastern shore, want to see what kind of antennas he would need to communicate ~10-14km. Wants to do experimenting. Has GPS unit on a boat to determine where signal will be. Directional antennas also an option. Open to suggestions, thinking about ChirpStack, where he is, LoRaWAN may not be as critical.

James - mentioned LoRa mesh protocols as possible solution

John - big issue, lagoons are not good locations for solar panels, must be inconspicuous, plus storms and wave action. Primary battery may be key since solar not good in lagoon.

James - also considering bluetooth, considering study based on different frequencies.

Dan- recommend starting simpler, back to base LoRa instead of LoRa WAN. probably double the distance you can reach because you dont need acknowledgement needed from LoRa WAN, also easier to program.

Martha - DIRT project, digital integrated research technology. Demonstrated need for an ability to get sensor data from inaccessible field sites to the user. As well as unobtrusive sensors!

Another project - TOMST soil moisture and temperature sensors at a mine waste area. Looking to see if metals in soil are correlated with plant spacing patterns.

Joe - used tile markers, has lots of ideas re salt marshes.

Jake- working on proposals! Remote sensing, ISAT spaceborne altimetry

General: ESIP at AGU this year, Ignite and Data Help Desk

Chris Gazoorian presentation

  • Upper Neversink Innovation Test Bed, NY upstate
  • All New York City water supply
  • Legacy monitoring: traditional stream monitoring + a few met stations + one ET station + deposition collection site
  • large suite of envirosensing devices and applications to figure out which works best
  • Basically anything you could ever want re: enviro data. Monitored as it supplies water.
  • Fish population research dovetails with hydrology, especially as local environment is spring fed
  • Paired water and air measurements at-a-station, 51 sites with HOBO TidBit sensors where radon and depth to bedrock is also collected.
  • Helps to identify how much the water responds to the local air temperatures.
  • Upper pigeon brook subbasin, many ground water springs destroy the cohesion of the granular sediment and cause debris flows.
  • Aquifer research in the neversink is a large component of the groundwater storage in the basin, trying to figure out the total volume/
  • Trail cameras check for stream ephemerality.
  • Water-air temperature sensitivity changes down the catchment
  • ML model for depth to bedrock, then can observe where there are large disparities in temperature equilibration timescales
  • Monitoring for radon to determine groundwater residence times.
  • O18 isotopes were also collected, show a highly seasonal dependence. The autumn isotopic signature is distinct from the spring signature
  • HVSR tremino sensors, require shear velocities for analysis of depth to bedrock
  • Thermal imagery can help attribute water sources by looking for colder groundwater seeping into active channels
  • Site recon with FO-DTS to map subsurface seepages. Can also use handheld thermal cameras.
  • Cables can be 1km long for FO-DTS, looking for preferential groundwater recharge zones, which can also be directly monitored.
  • Gauges run off of AC power, though some of the more remote sensors are run by solar, use high gain antennas as there is no cell service
  • UAS orthoimagery and thermal imagery
  • Fixed mount thermal went through some iterations, settled on FLIR A700, can stream the data with different protocols, allowing for customization.
  • Also have real time RGB imagery
  • Appears to be differntial groundwater dynamics between the alluvial floodplain and the hillslope seeps.
  • Rivers, if unconnected to groundwater, are quite more variable in temperature
  • Ideally scale this to the national level for groundwater inventory

Notes:

  • Remote sensing of water with microwaves, it is primarily sensitive to the water signal. Ultimate strategy must use all types of remote sensing, including in-situ sensor networks. Want to sense water at a variety of scales.
  • At low frequency, you can get dielectric profiles from subsurface!!!
  • Led to design of NASA AirMOSS radar, P band frequency was chosen to ensure soil water content below veg and surface
  • Collected data from all across the US, including 9 different Biomes
  • Can get down to -75 cm into the subsurface…
  • Inversion algorithm finds best set of scattering model parameters…
  • With 1000 flight hours, errors are reasonable with max error at 0.45 m
  • What happens with permafrost and P-band radar?
  • No direct active layer property measurements
  • P-band radar can resolve the depth to active layer remotely!!!!
    • Can generate time series with this methodology
  • Many variables that go into active layer occurrence over time, need more data to confirm.
  • UAS may be able to gap fill more expensive airborne acquisitions.
  • Software defined radar uses a low cost hardware platform that can be remotely configured for operating frequency, bandwidth, imaging mode, and power
  • Good estimation of water-table depths down to 12 FEET!
  • Can identify the snow surface and ground surface!
  • Trees make things harder
  • Custom hardware and software for WSN and UAV operations
  • Everything is autonomous re: the drone.
  • Good SNR below trees, can convert to soil moisture
  • UAS-based systems will be able to gap-fill larger more $$ datasets
  • Volume scattering at higher frequencies, even at P-band, we are sensitive to presence of roots. Larger rocks in the subsurface
  • NEON flies sites every 3 years lidar, curious about bathymetry applications?
  • Hoping to start a project with this drone based system, need lower frequencies. How to separate reflections from the top and bottom.
  • Scotty: cm scale environment at plot or landscape for surface characteristics as well as moisture constant. Can you get improve accuracy with the system for cm-scale characterization?
    • A: a qualified yes: cm-scale or sub-cm surface roughness, probably a yes. They have the EM wave roughness scale as a variable. We assume somewhere between .5 cm to cm roughness. Cm-scale resolution is probably not possible with current limit of bandwidth. However, the next best thing is using an analytical profile model. This makes it more possible

Time Stamps (ET):

17:11 Novick lab scales from leaf to whole plant.

17:12 leaf-level measurements done by leaf water potential and leaf level gas exchange

17:13 can get live read out from data in chamber, and fully controlled.

17:15 60 hz collection from Ameriflux tower in Morgan Monroe State Forest

15:18 sapflux sensors use thermopile embedded deep in the tree to measure values.

15:18 thermal dissipation is the temperature differential, lowest water flow is at highest temperature differential.

15:21 Reduce outside temperature by insulating from the outside world, bubble wrap, tape, etc. HVAC system reflective bubble wrap

15:21 hydrologic stress mechanism in water transport in plants

   Soil moisture and VPD (vapor water deficit)

15:22 Different species of plants regulate their stomata in different ways, more conservative in water use strategies, or more conservative in water use strategies.

15:23 use pressure bomb to see pressure on watr column, can determine stomatal activity.

15:24 pressure on water column can cause embolism in plants, “catastrophic hydraulic failure” during drought.

15:25 Convert sapflux data (transpiration) is converted to stomatal conductance

15:26 different common indiana trees have different conductance to VPD ratios,

15:27 tulip poplar has quite different conductance during wet vs dry conditions, sugar maple as well. White Oak, however, has a more risky behavior, has high rates of canopy conductance in the face of dry conditions.

15:28 Applied this methodology to wet and dry places, missouri, NC, and indiana. Not all species represented but similar species. In wet sites, still seeing large reductions in stomatal conductance that is driven from VPD.

15:30 In drier sites, soil moisture reductions become more important relative to vapor pressure deficits. Moving into different climate scenarios, regardless of soil heterogeneity, VPD is expected to increase everywhere with increasing temperatures, driving changes across species.

15:33 Species-specific response to change, generally done on the ground which can be subjective…current work is on how to identify specific species canopies in the phenocam to have more objective outlook on shifts in season based on climate change.

15:37 Drought forecasting using phenology and leaf on time could be useful.

15:39 Build everything in lab, question from John Porter: Can you comment on how long the sap sensors are able to run between servicing/replacement?  Also, how many replicate trees do you typically require to characterize a species sap flow? If no critters or storms, can go for around a month! Never use less than four for replicate trees.

15:43 Line power or solar? Usually line power, but they can be installed with solar power as well. Marine battery connected solar panels.

15:44 Dan Fuka question: 18 trees monitored, can model one tree accurately, but 18 trees is an amazing dataset which you could go to the NSF with for anything mentioning “scale”

15:45 Have you considered doing IR? Interested in IR. this book is great: https://www.abebooks.com/servlet/SearchResults?isbn=0387902287&cm_sp=mbc-_-ISBN-_-all

15:47 dan set corn on fire with heaters

15:48 UVM and NY doing sap sensors in sleeper watershed. ESIP summer 2023 is in burlington

15:50 Have you looked at leaf anatomy? Oak leaves might be more drought resistant from a thickened cuticle…Have not looked at leaf anatomy. But have a growth chamber..colleague of Sander’s is looking at white oak and sugar maple. Stay tuned to lab. Specific leaf area would be useful as well. Stomatal density could be playing a role. Pathways of water vapor

15:53 They used CS16’s to measure, what sort of calibration stuff do you have to do with those? Question from James Gallagher.

  • https://www.campbellsci.com/cs616-reflectometer

15:55 Soil water potential might be better than soil moisture for plant water availability.

15:57 Check data weekly to make sure sensors are off. Limitation is built sensors.

15:58 Ken Connor at Campbell Scientific is a good contact [[1]]

15:59 Bullet style camera, code developed out of canadian lab.

Time Stamps (ET):

17:13 - Green Stream Technologies www.greenstream.com  is an enviro tech company based in Wake Forest NC as well as ops in VA and hampton roads area.

17:14 - overarching goal is to make envirosensing easy and affordable for customers. This is needed due to imminent climate change threats. Also modernization of legacy equipment, doing more with less data-wise

17:15 - this can be costly, legacy systems themselves and maintenance is expensive. W.r.t GS, end -to end solution provider for customers. Design, develop and deploy those solutions

17:16 - 4 columns to solution, sensor network, wireless comms, cloud services, real-time data.  LoRa WAN,  satellites in the form of GOES. cloud based program.

17:17 - more customers are adopting cloud providers, (Azure, AWS, Google), attempt to make data real-time or close as possible, multiple ways for customers to consume, dashboards are built and provided to customers. Dashboards are adaptable on a per-client basis.

17:18 - API’s are provided for customers for get and post reqs. Additionally, sensors can talk directly to customers platforms as well.

17:19 - In house toolset: Electronics (R & D), systems eng. Computer science (programming at the embedded level up to the cloud level), mech eng. (install), business law and contracting, service operations (maintenance of products afterwards).

17:21 - started off with a low cost low footprint sensor with mainly off the shelf parts and packaging. Easy to install and low maintenance req.

17:22 - govt customers as well as private citizens are buyers.

17:22 - solar powered, internal batteries, no external infrastructure for deployment, work on LTE and LoRa WAN

17:23 - reports every six minutes (adjustable). Streaming real time into system and pulled in by customers. Provide real time dashboards with associated APIs

17:24 - all the sensors deployed in NC fed into FIMAN https://fiman.nc.gov system (flood inundation mapping and alert network) and VIMS StormSense and onto NWS.

17:25 - city state and county level, entities will purchase and then GS connects and deploys.

17:25 - overcoming the 3 V’s, vegetation, varmints, and vandals. Have deployed filtering algos to minimize noise associated with 3 V’s. Bugs and spiders like the sensors (the cones).

17:27 - sometimes people rob the sensor :(

17:27 - GS also does larger deployments, sensors with larger footprints. Deployed on piers in the OBX which required specific solutions and installed by GS.

17:29 - CAD done in house, fusion 360. Everything is modeled for visualization as well as working out the kinks beforehand. The model is then sent out for fabrication. Built and assembled in house then installed.

17:30 - GS can also deploy 3rd party devices

17:32 - case study upgrading 3G devices for VA Beach to LTE.

17:33 - large - scale deployment of radar, 71 radar sensors put in for the state of NC. LTE and GOES satellite comms. All campbell scientific, customer had concept for enclosure but that was it. GS did the mount solutions. Fabricated bespoke boxes to make them 100p watertight. In house test jigs were built. Given access to network management system for NC, called contrail, configured that for the state. Helped with encoding and decoding from GOES.

17:37 - coordinated lane closure and traffic control for deployments. Currently, GS is working with USGS for a pilot project in Frankford Creek,  request from USGS, boxes need to talk to AWS and support multiple wireless communications. Designed proprietary electronics to support LoRaWAN, LTE, bluetooth for multiple forms of communication. This is important for the sensor to be able to leverage different comm channels for different things: events vs. updates etc. Wifi also allows wireless configuration via set up mode. Acts as a web server for updates, then can re boot and change comm configuration. Communicating with AWS IoT core, mqtt and https. Jobs capability with AWS which can help for updates. Boxes report every 6 min with LTE followup with LoRaWAN. All brand new hardware.

17:41 - building battery packs with solar charging, can run off 6 V solar panels and recharge itself.

17:43 - in house building of electronics helps to save costs and improve performance.

17:44 - Also building a suite of interface cards and libraries around those, concept is to make this modular for end user.

17:45 - Network Management: event publishing, device config, job processing, file download, application management.

17:46 - Make dev kits moving to industrial, multiple comms, modular interface cards, firmware libraries, common dev tools.

17:48 - Needs: mobile apps, circuit board layout, firmware coding, building libraries, building network management, also, decision needs to be made to be OS or proprietary. Some risk comes with either option.

Scotty - big fan of publishing mature code base and fork it off for proprietary purposes etc. Contact matt bartos for intern help https://www.caee.utexas.edu/people/faculty/faculty-directory/bartos

scotty: question for at-scale deployment. Pushing updates is different than set and forget. Interesting category of hardware emerging. Question about pushing OTA updates one by one or across the board.

Answer: stairstepping, in house testing first, but will push based on customer reqs as opposed to all at once or by fleet.

17:57 - Joseph, enjoys the CAD model creation, which is helpful for the end user (like the USGS).

Answer: CAD models gives flexibility to look at a myriad of solutions rather than a simple diagram. Models have been VERY worth it in long run. Models of circuit boards are also created.

18:00 - Micropython question from James Gallagher, how useful was it vs C++.

Answer Using pycom, performance has been very good, little devices can be multi-threaded !!! and secure SSL communication. Maker community is also very good and useful. Overall pleasantly surprised with it. It can do async ops as well.

18:02 - GOES-R communication and iridium. What's the operation difference between those two?

Answer: analysis done in proposal, are sites where u neet sat comms. GOES is one-way trip. It’s robust and it works, footprint is large relatively, message size is robust, but only once an hour default transmission, free for govt entity which is a big one. Window is small (170 char window). Iridium is ~50 character window. Iridium is cheap up front but has higher comms cost. Antenna size is tough with GOES, IoT via satellite is lower cost for data and hardware with smaller antenna.

18:06 - Joseph, some frustration with iridium at usgs. Iridium pricing :C.

18:07 - Matt Gyves, will deploy combo LTE/LoRa/Wifi Green Stream gauges on USGS pilot at frankford creek in Philadelphia.

Time Stamps (ET):

17:05 - Intros

17:06 - OPeNDAP, James G. and Martha A. Dirt Project: sensor web deployed in alpine envs, uses LoRA tech to take measurements from a group of distributed sensors and sends it to a central node, which uses iridium tech to send the info back to server. Master node is proofed, as well as leaf nodes, of which there will be multiple talking back to master node. Leaf node was installed a year ago in a research plot to test. Data has been plotted and sent back to the node (1h interval). Batteries are good / healthy with good voltage. Projected 10 years of battery life: microprocessor based, uses microamps (20) while sleeping. Wakes up once an hour and does ~3s of work. Probably do NOT need to boost. Tested in Goat Flat (impractical to have solar panels or external/separate power sources). Also installed soil moisture probes but difficult in the rockies.

17:15 - Scotty S. new project: 5 year NSF harnessing data revolution for fire science. Deploying experimental sensors in UAVs, fly over pre and post fire plots as well as during. Experiment with high resolution sub-centimeter detection of fuel sources. Whole process of computer vision + sensor fusion is exciting and cutting edge! LoRA Wan gateways in tahoe region for community science. Answering questions that state wants answered around lake tahoe, as well as let community members deploy sensors after following a short tutorial. Hoping to cross-pollinate with ESIP!

17:17 John P. - robotic controller for stepper motor (https://photos.app.goo.gl/6wkYNU7ZHsTUQUsz8)  that can be used in middle of bay. Essentially goes inside a stainless steel tube. Security sensor reed switches can go inside the box and you can turn things on and off without opening the tube. Sensor is designed to counteract tidal action to get consistent data. For work in shallow lagoons, solar panels are not good. They don’t float, they attract thieves and others. Really looking to get into LoRA out there…asks scotty if they need to set up their own LoRA nodes. How do you deal with LoRAWAN gateway pricing on state grants?

17:21 Allison M: run farm, having trouble making thermometers work cold settings vis a vis bluetooth. Any help is desired! Otherwise helps with social media and communications.

17:22 Mark L. Jefferson Project: operates a sensor project on lake george, 5 vertical profiling platforms. YSI ones were great so they built their own. Also deployed on other lakes around. Deployed for harmful algal bloom research. Kevin Rose is director, sensors are focused on spatial resolution, 26 locations on Lake George alone. New to group, hoping to learn. Also looking to improve QA/QC as it is currently time intensive.

17:26: Bhuwan T. USDA funding assessing role of wind breaks, getting data from remote sensing as well as machine learning. Wants to learn if can deploy sensors to look at wind damage with UAV, also teaching a course on urban planning, wants to bring in sensors into that class.

17:29 Dan F: horse-tail mounted sensors!!!! Different ways to engage ag industry and funders. Playing with sensors that are designed to be cheap ~ 25$. USDA is tied to ESRI! ASR6502, can cut power to a trickle, and burst when data is back. Fits in a nice chinese lightbulb. USDA is federal, but its all china based…and so thats a no go. Now Dan has found a laser cutter! Which makes a nice little housing unit. Teamed up to design replacement for microprocessor and other replacements. Has to get data into ESRI software. Campbell Scientific doesnt wanna talk to ESRI and vice versa. Big roadblock. Most of what Dan will be doing next year will be walking that line.

17:39 Joseph B. agrees with china prohibition makes hard to acquire parts. Joseph is trying to establish a liaison between the USGS and ESIP—academics, industry, etc. also tasked with transitioning sensor networks for next gen. How do we have networks without borders etc? Key focus this year, trying to get DCP, also LoRA WAN surveying for LoRA WAN working in dense urban environments. Also connected with California Water Science Center

17:47 Dominant use of GOES @ USGS, existing data collection workflow.

Scotty S. Q: LoRA gateway protocol for not standard sensors that get jammed into transmission which unload it in goes gateway and from that get disseminated into things network automatically? - Joseph says yes! Can we keep the existing pipeline via retrofitting ? 30-45k to start a gauge, 15k to maintain gauge down the line…if a node can stand up that can provide another gauge, would be helpful.

GOES window. Window of time to send sensor data back and forth. This would be a total alternative to using Iridium. Given a modem, you have a certain bandwidth you can press into the timewindow you’re given. If you’re only transmitting data from one sensor, you’re wasting bandwidth. It’s a very robust global delivery system due to the infrastructure…it is cheaper too!

NRCS uses snotel, media burst still. The footprint of the antenna is huge! 6m wavelength antenna. GOES uses decent amt. of power. Campbell Scientific modem is not cheap though.

17:12 - Beginning of John Fulton’s talk: Post-wildfire Streamgaging

17:14 NonContact vs Conventional Stream gaging - these are used in high altitude streams

17:15 basic streamgage measures…stage!, which has been referenced to a datum. Discharge has a relationship with stage.

17:16 -  ADCP: produces a distribution of velocity and depth which gives Q. this correlates to stage. Rating curve is generated from this.

17:17 - NonContact Monitoring in Burn Scars - ensemble vs ground based methods, when paired, can minimize false alarms.

17:20 30ft/s stream velocities can damage sensors, even no contact ones!

17:21 Dataloggers with solar panels, rain gauge buckets, soil moisture probes. This is a functional unit

17:22, stage radars and velocity radars help to monitor the stream continuously

17:23 - 1 min frequencies between data points. Have radar, rain gage. Also transmit data quality in the form of signal to noise ratio.

17:25 - Lag times are crucial, especially based on velocity which is what is fed to alert networks. Earlier response in velocity than stage!

17:27 need techniques to quantify area during floods, since the hydraulic geometry is so changed.

17:29 uses Q = phi * u_max * A

Mean vel of channel: max vel of channel

Idea is to take surface velocity value and give mean channel velocity

U_max doesnt need historical data

17:33 Terrestrial lidar can be used to assess area of channel before and after

17:37 Phi is the mean channel area divided by max velocity !

17:45 - stage area ratings are imperative!

17:49 - Daniel Fuka gives update on Summer Meeting session proposal!!!

17:50 - demonstrate all components of data workflow at ESIP summer meeting.

17:04 Intro Welcome from Scotty

17:07 Intros from all

17:10 Thinking about cluster theme: wildfire aligned themes for the next year or so…opportunity for questions. Floor is opened.

17:11 ESIP is pushing in-person meeting for summer and virtual for winter 2023: opportunity for hands-on workshop at summer meeting?

17:12 Virtual meetings lower accessibility barrier for meetings…

17:13 Sensor workshop will be hard to do, but there are many resources available… could be from getting sensors to work to data gathering / labelling / cleaning. etc making it FAIR. - D. Fuka.

17:14 J-link debugging for microcontroller units - small demo possibly from James Gallagher

17:15 just for potential comradery: there are other clusters talking about trying to do more of a workshop/hands on session for ESIP Summer as well (Semantic Harmonization) -- so, there may be more general enthusiasm and co-support for hands on! - Bar

17:16 USDA partnerships in innovation would be good contact, possible sponsor. On its way

17:17 Two people stepping up for summer meeting! Daniel F. and James G.

17:19 Making it an outdoor session would be ideal…introduction to local host in Philadelphia could be good. - Daniel Fuka. +1 from Martha. Will need to figure out how this meshes with the meeting plan..

17:23 Necessary to plan for these insofar as when folks come unprepared its derails the workshop.

17:25 injecting problems to be debugged that we know how to debug. Details do need to be worked out a long time in advance..

17:27 just for potential comradery: there are other clusters talking about trying to do more of a workshop/hands on session for ESIP Summer as well (Semantic Harmonization) -- so, there may be more general enthusiasm and co-support for hands on! - Bar

17:30 Consider a debug-specific session too? Could help account for overflow

17:30 Switching topics now: Wildfire

17:31 Ag and Climate cluster unanimously voted to go on a hiatus…

17:32 Disaster Lifecycle has gamed out next three meetings worth of content re: wildfire. Seems like energy is headed that direction.

17:33 Envirosensing is technical cluster and in a good position to contribute, but glad to continue in an advisory role. ESIP can make impacts by connecting stakeholders.

17:34 When opportunity for cross over, let Envirosensing cluster know.

17:35 Guy is moving on in his role as NEON participant, thanks all and says someone new will rotate into the role.

17:37 USGS and NOAA facing same problems as NEON re data networks for sensor deployment. Cyber security will play a large role as sensor networks become more integral

17:39 Joseph introduces slides for poster about envirosensing cluster

Can help to connect people in agencies, academia, private sector

17:42 Proposal prep: small (<10k) and medium (>10k - 60k) concerning next gen water systems, sensor networks.

17:47 Whats obvious to Envirosensing cluster isnt to everyone. Scotty, Martha, Jake will work on poster with joseph, others feel free to help

17:47 Next few calls will be speakers, supporting hands on workshop meetings may be offline or could be fit in.

17:05 - Introductions

17:12 Recap of Meeting: discussing high-level wildfire concepts from envirosensing context. Stakeholders at meeting were important and helpful: e.g. Chief Winnacker from ESIP meeting. Interdisciplinary conversation on how to apply science-driven tech to tactical response for wildfire. Also for mitigation before and after fire events. Long term observation is bread and butter of cluster, but how can we increase the velocity of the data? How can be better operationalize data for a wider audience? We want to see more thematically driven collaboration across the clusters with longer timeframes (1-2 years) on topics like wildfire. ESIP doesn’t have to deliver products, but needs to foment conversation and connections between experts.

17:18: From USGS perspective, fast or real-time data is crucial. Even binary data can be helpful at high velocity. - Joseph

17:18 Sensor use in context: where do you put sensors in context of a wild-fire? Can we position things in place ahead of time? Chief Dave Winnacker helped to ground the discussion in what responders really need. - Martha

17:20 Air quality aspect of sensing wildfires should be considered. Additionally, how possible is it to alert those on the ground? Especially when wildfires are fast and unpredictable. Would deployable sensors be effective here? - Steve Young

17:22 Air quality and distributed sensors: chief winnacker stated that he would like to have that sort of data summarized quickly and efficiently. For air quality, you’re wading into proprietary data which can be difficult to handle. Can we combine air quality sensors with the ability to turn on sprinklers in a back-yard (from winnacker).

17:27 OpenAQ with distributed sensors. Open EPA solicitation here: https://www.epa.gov/arp/enhanced-air-quality-monitoring-funding-under-arp

17:28 Situational awareness, deployable sensors could be put into action by firecrews? - Joseph

17:30 Scotty shows slide showing possible pathways for data collection to analysis and delivery.

17:32 The Chief mentioned a sort of fire sensor "fence" proof of concept that used a perimeter of sensors/IOT model to detect a wildfire within a very finite area. - Steve Young

17:33 Josh Lieberman Open Geospatial Data Consortium. Working on a data product that is designed for stakeholders on the ground to summarize many data.

17:36 Vis a vis infrastructure, maintenance is often the bottleneck, as it will incur costs ad infinitum - Brian Wee

17:39 The government funding to improve broadband access in underserved areas might create opportunities to improve connectivity for sensors - Steve Young

17:40 Emerging technology is included in infrastructure bill to a certain degree: esp. Regarding AI/ML

17:41 Scotty shares slide: regarding R&D for wildfire, its largely piecemeal as is.

How best to merge UAS data with in situ data? Machine Learning ready training data sets will be needed and in-demand as data products.

17:47 Monthly calls will be speakers, but we will stay close beside wildfire focus of ESIP

17:48 Re: Artificial Intelligence and data-ready AI data is hyper important.

17:49 Can we use in-situ sensu deployments to perform image tagging on image datasets

17:50 We have all the sensors, ESIP, strong foundation, create a NEW federal repository through a federal unit. One agency doesn’t have a federal data repository which is USDA: project is called XX. covers all states with reps in every county. They are currently trying to build up data repository. Could we use this to build a ground-up network?

17:52 https://www.nifc.gov/fire-information from Steve Young

17:54 NIFC (National Interagency Fire Center) is one place to look, but interestingly not a NASA partner

17:55 Two people who come to mind for cloud-based architecture/infinitely scalable data repos. Colin Bode and Matt Bartos

17:58 NASA workshop upcoming. Info gathering stage https://nari.arc.nasa.gov/sites/default/files/attachments/Feb2022_SMDWorkshop_ParticipantAgenda_v2.pdf

6:03 USDA also has to host almost every kind of data which would give some

Notes

Call for a speaker at the joint Ag Climate & Envirosensing, reach out if so!

James Gallagher: building units and deploying/testing is difficult, want to go from star network topology to Mesh topology.  Asks if anyone has experience with simulating sensor networks.

  • Power budget is limited, sensors can only function a few seconds per hour. Mesh networking edge nodes are senders and receivers, transmits are expensive. Simulating power consumption is ideal.
  • Mini-net but for the edge, ability to simulate power budgets instead of just network topologies.
  • https://www.dryad.net/. Presentation in mesh over LoRa at the Tactical Fire Remote Sensing Advisory Committee (TFRSAC: pronounced “tiffer-sac”) meeting co-organized by the USDA Forest Service / NASA on 2021-12-01 and 2021-12-02.
  • Another link https://publish.illinois.edu/ymb/ that might be helpful
  • Good computer science + engineering project to determine optimal power consumption for sensor networks (?). Could start with discrete sensor simulations, reaching out to DRYAD might be helpful. It may be proprietary but should be reached out to.
  • Electrical engineering simulation + sensor network simulation. NSF may be interested in funding via CSSI, framework with element pilot then submit the grant :). The proposal to develop such a software would be worth conversation with a program manager
  • David LeBauer sent link: https://beta.nsf.gov/funding/opportunities/communications-circuits-and-sensing-systems-ccss-0 for possible resource concerning Electrical Engineering research.

LoRa implementation, has anyone employed Dragino sensors?

  • Programming was ‘funky’ re: multiple ethernet connections and poor documentation. Linux box with YUN + arduino. Therefore cannot run much code. Some units arent rugged enough to be outdoors
  • Daniel Fuka: much of Dragino is simple via an OpenWRT interface. However, they do not allow multichannel LoRa unless you purchase a much more expensive unit. Not great about sharing source code. Sensors are efficient. They can be hardwired for more efficiency but a good place to start.
  • Wondering about Dragino uses for meteorological applications. The unit with the combined MCU + LoRa. Cannot code to be only single channel.
  • LoRa experimentation is usually one-off (individual sensors, gateways) How to deploy gateways at scale? Containerized + automated codestack. 10-20 that can all be updated in a uniform way. Any thought of software management automation with at-scale gateway deployments of LoRa?
  • Daniel Fuka mentions he has backed out of LoRa at scale because you need reliable two way communication, range is degraded.
  • Can you manage networked gateways easily?
  • Cheap Dragino router has auto-update since its OpenWRT. Can establish connection and confirm updates remotely. On a 1x1 with autoupdates happening every few weeks. However, they do die sometimes!
  • Final call for LoRa discussion: moving on to networking and network management from routing perspective

Question: are people running networks using one network point or multiple? If multiple, how do you allow sensors to utilize multiple network connections.

  • John Porter: one wireless backhaul network with ethernet. Sometimes have radio serial links but are right on the net. Don’t have to deal with those issues of different routing.
  • Would multiple paths out still be useful? Wanted? Or not needed at all?
  • John Porter, if main node is down, network is down and is sometimes inaccessible. Have considered setting a cellular modem but routing questions make this difficult. Would consider doing something that is switched, RaspPi might check if primary network is up and then switching to a secondary if it isnt. Interested in LoRa but havent set up yet.
  • Local Area networks which are tied back into a wider research network. Consider a classic network topology (WAN) that has multiple ways to get back to the network, cellular, p2p network, fiber, etc. routing on that uses classic IPV4 wide area routing protocols. Value in enterprise type routing with these networks. Multiple paths out will be feasible soon

There is a role for network engineering and organized sensor networks. How can we bring network engineering to scientific sensing networks? How to do this is a good question!

  • Cross-training w/ graduate students could be useful, even just a little networking.
  • Networking has to be a little simpler, though. Wired/Wireless with cell back up works but reverse engineering ad-hoc systems is still difficult. Simpler might be better.
  • To what extent are folks thinking about two-way needs? Sensor retasking or algo changes.
  • Starlink is cool but is large and requires a lot of energy. Might be too large for the usecase
  • new versions of sensors will come out soon that are more efficient? Could be a space to watch. Some people are thinking of provisioning 5G directly from satellites to handsets (not possible now but maybe 5-10 years down the line)

Field has moved from specific science question sensor networks to more general. How can you change the velocity of data and make a network more responsive? Differential timescales of need depending on question.

  • Want to be able to deploy systems capable of multiple tasks. Pushing automation might be more valuable

Daniel Fuka suggests FI dog collar (touches on multiple networks. Prefers bluetooth, then wifi, then cellular). GPS dog collar. Nice general target for networking.

  • Cow collars for tracking/fencing collars in ag. V cool.

Any applications for drones? LoRa instruments cheap drones. Throw a package onto and network back through LoRa. get 9 km.

  • Intel RealSense LiDAR unit. Have to fly at night. Connects to a raspberry pi which spits back data through wifi or possible LoRa with less data. Radar is wallobot (?) with api package and 15 different frequencies.

Envirosensing Monthly Meeting

[Link to Recording]

Attendees: Joseph Bell, John Porter, Scotty Strachan, Ethan McMahon, Allison Mills, Kristina Fauss, Martha Apple, David Coyle, Guy Lit, Megan Carter, Daniel Fuka

Announcements:

Cluster is exploring collaboration with the Agriculture and Climate cluster relating to wildfire.

Notes:

  • Possible collaborations with Agriculture and Climate Cluster relating to wildfire.
* Ag Climate and Envirosensing cluster share a transition zone: in situ monitoring and observation collection for analysis.

* New technology emerging in wildfire monitoring. Where are the knowledge gaps for both researchers and response teams, and how can new sensor technology address them?

* Emerging sensor technology with a wildfire focus: Wildfire detection using cameras placed on a tower with landscape view, smoke detection triggers camera to zoom in and run other algorithms detecting fire/ignition.

* UC San Diego is generating real time fire spread model maps based on local meteorology and ignition points.
  • Discussion on spatial locations and the sensors available to assess what we have and where it may work:
* Feasibility to air drop (consumable) sensors into wildfire zones.

* "Sit and wait" - type sensors that chirp periodically and ping on detection of an event.

* Citizen science in the deployment of small sensor networks (dormant, pre-fire).

* LORA logistics and feasibility: canopy penetration, functional in ravines or complex terrain?

* 3D printed weather stations are being produced, build on this idea.

* Immediate Post fire data collection is also important - soil hydrophobicity is important to know immediately after the fire due to direct impact on flood risk and ecosystem recovery; typically measured manually but may be an opportunity for drone deployed sensors.

** Building on above: With drones, instead of using imagery, equip the drone with multispectral radar - before and after precipitation event to capture state change at the surface - however the inexpensive L515 Intel Lidar ($300) sensor is being discontinued
  • What sensing would support teams fighting fire?
* Tracking people - including location, but also time since deployed or most recent rest.

* Smart home sprinklers - which would allow the firefighting team (or automatic heat detection) to turn on sprinklers in the community. However this is dependent on electricity & internet (vulnerable during wildfire), a problem of network resilience ~ LoRa, Starnet

* Telemetry challenges: LoRaWAN is a multifrequency gateway, requires 2 way communication, acknowledgement, and often authentication - less capable for the above uses? 

* USGS Geohazards program is looking into this, absent from charter is a connection with local infrastructure and municipalities.

Envirosensing Monthly Meeting

Guest Speaker Amber S. Jones: Techniques for increased automation of aquatic sensor post processing in python.

[Link to Recording]

Attendees: Joseph Bell, John Porter, Scotty Strachan, Kristina Fauss, David Coyle, Guy Lit, Megan Carter, Daniel Fuka, Amber Jones, Jeffery Horsburgh, Bill Teng, Felimon Gayanilo, Matt Bartos, James Gallagher, Adam Kennedy, Renee Brown, Brian Wee

Announcements:

  • ESIP Sponsored Bystander Training: September 27, 2021
  • Envirosensing and Ag & Climate Cluster may be partnering on sessions in the summer/winter meetings; Envirosensing members are invited to join Ag & Climate Cluster Monthly meetings.

Timestamped Notes: 

12:30 Guest presentation begins:

14:00 Challenges of post processing: Sensor Quality Control 

14:25 Challenges of sensor quality control: large volume of data, tool accessibility, tedious, large discrepancy of corrections made by technicians - need for reproducibility and standards.

15:30 PY Hydro QC: Python package for quality control available on github, open source.

16:15 Package workflow:

* Rules Based preprocessing - anomalies are identified using basic rules, such as values recorded out of the possible range of a sensor.

* Calibration preprocessing - drift of aquatic sensors disturbs calibration, but this can be fixed in this stage.

* Regression models - ARIMA and LSTM models explored; model estimates and residuals help identify anomalies.

* Anomaly detection and post processing - thresholds determine whether a point is classified as an anomaly; a widening function may be used to classify anomalous events from points; an aggregating function may incorporate detections from multiple models.

** 21:10 Detection Results: In comparison of algorithm detections to labels applied by technicians the ARIMA model performed best; oversensitivity is preferred over undersensitivity - too many detections can be narrowed down by a technician.

* Correction - ARIMA models are used to generate a forward cast from pre-event data and a backcast from post-event data, which are blended to create the model correction; the algorithm is able to forecast diurnal cycles.

25:17 Conclusions and Recommendations: 

* Rules based detection is an important component and could be made more complex.

* Drift correction and calibration can be the most time consuming step in manual QC and therefore automation should be increased, which should also increase consistency.

* The model presented was effective and its sensitivity was dependent on threshold settings.

* The correction algorithm was able to approximate diurnal patterns and each event does require review.

* The package can be used in script or notebooks but does require some python experience.

* Package design is modular and is therefore able to accommodate future additions to the QC process.

* Technician review is required for points noted by the model, but far fewer than purely manual QC; technician review is required for corrections, but the model is able to provide corrections a human could not.

27:45 Presentation concludes; Q&A:

Updates on work: Package is now published on the python package index, so it may be installed into a user’s python environment, examples are also available online.

A couple of the models tested were multivariate, but generally did not outperform univariate alternatives.

Calibration events - model assumes technician will supply a date of calibration for drift correction.

Addressing codependence? This could be implemented as rules defining specific “impossible” conditions among multiple variables (at the “Rules” Step).

47:20 New Discussion Topic: Ag & Climate Cluster will be discussing the best ways to observe pre, during, and post wildfire processes; such as merging remotely sensed and in-situ data.

* Ag & Climate Cluster will be hosting wildfire management and mitigation stakeholders over the next three months - what do they need and where can technology fill the gaps?

Envirosensing Monthly Meeting

[Link to recording]

Attendees: Matt Bartos, Scotty Strachan, Ethan McMahon, Kristina Fauss, Renee Brown, David Coyle, James Gallagher, Guy Lit, Megan Carter, Daniel Fuka, John Porter

Announcements:

Summer meeting session: 3 people confirmed… a few more in the works

Notes:

  • Vendor Discussion
How to bring in vendors to the Cluster?

* Megan: connected with someone from FieldKit —> will send that info to Cluster leadership team

* Some concerns about bringing in vendors, don’t want it to be a sales pitch

* James: what about Sparkfun or adafruit?

* Scotty: likes James’ idea of bringing in open hardware vendors since we’re already working in this space.

* Megan: With respect to FieldKit, I’d be curious to ask them to talk about their vision for the wiki of open-source sensor information they are planning to build. And what they plan to include and who do you want to contribute/most collaborate with?

* John: ask vendors to tell a story.. e.g., what is the story behind a successful sensor? What are the trends you’re seeing?

* Megan: harness the ESIP theme of this year- innovation.. Tell us a story about that.
  • Virtual office hours
* Scotty: what if (in lieu of virtual microtutorial project, for now because people are still overloaded with commitments due to covid, etc.) Cluster offered “virtual office hours” that could be broadcast to email list and beyond?

* Ethan: +1 re office hours. It's similar to data stewards. Our cluster would serve as a resource and learn and document what we hear.

* Megan: Agreed on office hours also - will take some effort to recruit people to come ask questions, though, so good to develop a communication plan re: the opportunity. Hardest part is getting people to show up. Recommend keeping it during the regular meeting time to simplify workload

* Renée: like the idea of doing this 1-2x year during telecon.

* Ethan: I agree. We don't know if there are others in the ESIP realm who are interested; if they are interested then why haven't they attended these meetings

* Megan: reach out to your networks

* Ethan: how about we do this within our own Cluster? This could be a place where cluster members could ask each other questions about their problem.

* Megan: That’s a really good point - these calls should benefit you all - not just be a service to others.

* Matt: Setting up a new lab, has to go through digikey (can’t purchase through adafruit or sparkfun)... has questions about what to buy. Second example, for office hours- opened a discord server with the intent of having students talk to each other- but they ended up having questions for him… a perpetual office hours. For office hours, definitely need one or more persons to lead it to help with organizational structure

* Scotty: we also have a Slack channel… we aren’t using it.

* Megan: can use Data Help Desk model… use a form to ask people to submit questions

* Megan: can there be a connection between Virtual Office Hours and microtutorials?

* Scotty: yes
    • Summer meeting session:
* 3 people confirmed… a few more in the works

* How much time should we set aside for discussion?

* Daniel has a topic he could talk on if there is a slot available re: PCBs

** He also suggested Nate, founder of SparkFun 

** James: @Dan Who do you use for PCBs and population?

** Dan: Makerfabs is our last batch, but using their open design. https://www.makerfabs.com/
  • ESIP Lab:
* https://www.esipfed.org/lab/funding-opportunities/2021-spring-esip-lab-request-for-proposals

* Daniel is putting something in
  • Daniel Fuka to Everyone (3:59 PM)
    • Here is a fun LoRa based soil moisture sensor we are testing and I am adapting to add GPS

Envirosensing Monthly Meeting

[Link to recording]

Attendees: Matt Bartos, Joseph Bell, Scotty Strachan, Ethan McMahon, Kristina Fauss, Renee Brown, Adam Kennedy, Martha Apple, David Coyle, James Gallagher, Guy Lit, Megan Carter, Daniel Fuka

Announcements:

Summer meeting Flash Talks proposal accepted - very short, what are your recent successes? Can be “half-baked” - there will be an email going out soon for presenters, topics can be broadly related from physical sensors to data quality control (but EnviroSensing generally not focused on satellites sensors)

Please submit presenters for the ESIP Summer Meeting EnviroSensing Cluster session!

Two complementary speakers who have not been to ESIP before (Megan)


Notes:

  • General Discussion
* Shifts in funding are coming from the federal level with the new administration, expect new govt budget on climate change, covid, and the economy and air water budget changes - opportunities to fund sensors to be placed outside of typical natural pristine areas, like metropolitan areas.

* Public summaries of budget changes published, Ethann McMahon will send for distribution to cluster/ESIP listserve or slack: Biden’s budget request (https://www.whitehouse.gov/wp-content/uploads/2021/04/FY2022-Discretionary-Request.pdf) (58 page version). 3 page summary (https://www.whitehouse.gov/wp-content/uploads/2021/04/FY2022-Discretionary-Request-Press-Release.pdf)
  • Telemetry Discussion
* Mixed wireless and wired networking (for research) needs help to scale up

* New opportunities opening in the fields of telemetry and end-to-end data flow for our community to engage on these topics and contribute expertise; there is funding available for broadband connectivity for education, hard to reach communities, and science - these opportunities tend to be missing people with expertise like that of Envirosensing members

* Adam shared updates about Andrews wireless: Wired Internet has been down since last year’s wildfire, was previously T1 line, but has upgraded to Ubiquiti AirFiber line with 4’ dishes (wireless communication), but now fighting to defend unlicensed bands, it’s exciting that 6ghz is being added to unlicensed channels. How do we remain on a clean frequency on the unlicensed band? How do we generate revenue to support the service (which is expensive to maintain)? Is using low-power Ubiquiti radios (2.4 Ghz + 900 Mhz) for internal network connections that are only turned on when needed to save power, especially in the winter, feasible? Options for up sites with to 75 people during the summer, all of our telemetry passes through the system?

* David: Ondas.com https://www.ondas.com/ 

* Joe: GOES channels are going private (GOES is a satellite-based telemetry)

* Renee: There is an extensive wifi network at Sevilleta through Ubiquiti, there is also good line of sight which allows good wireless links and good bandwidth at the field station. The water quality monitor sites are in remote places with no cell service - impractical to set up a wifi network there. In Antarctica, Iridium is the only thing that works. Using Ubiquiti mostly now, standard wifi, radios, recently converted 2g to 5g - Are you using standard wifi vs proprietary for ubiquiti? Anyone have experience with this?

* Adam: Just bought some AC’s Airview M2 nanostation , we don't have any concern with anything Ubiquiti might change to - all is compatible within Ubiquiti, biggest benefit is to go down to 5200 frequency as it is cleaner => recommendation get a couple and see how they work

* Renee/Adam: Wired connection is vulnerable to physical damage (fire, cut). Wifi is a good backup but we need better than 1g for today’s data expectations

* Scotty: Starlink has advantages, particularly if Starlink starts including mobile applications

* David Coyle: Starlink (unlike Iridium) does not have many fail safes/redundancy

* Scotty: Starlink goes down sometimes, but when it’s up it works really well, could work well as a secondary/tertiary internet connection depending on the application

* Dan: Lora is 250 bytes per second

Announcements:

There will be a data help desk - watch ESIP channels, all help is welcome.”Curious about the Data Help Desk at EGU21? Check out http://bit.ly/DataHelpEGU21.”

Summer session proposals by April 16 “ESIP Summer Meeting details: https://2021esipsummermeeting.sched.com/info (registration open now and sessions accepted now through 4/16)”

No envirosensing AGU session this year - wait till next year/AGU is back in person, but feel free to reach out if you have questions or would like support in your own AGU activities


Notes:

  • AGU Discussion
* AGU accessibility does not compare online vs in person

* Unclear if AGU will be fully virtual or not

* MacGyver session at AGU might be a good place for Envirosensing member topics, Envirosensing cluster will not be organizing a session
  • Video Microtutorials
* How to continue knowledge transfer/teaching/discovery, building on momentum from the world moving virtual 

* Are there existing tools/templates/guidance to produce?

* Work towards developing a task matrix

* Important to include in microtutorials: Order of operations, plan or strategy relating to the instruments, transferring tacit knowledge, knowledge of hazards

* Address the problem: saturation of poorly organized material, not easy to get what you need (accurate, detailed quality) on a quick pass

* How to classify, order, tag, summarize, so that people can decide if the tutorial suits their needs quickly

* What’s been done in the space? Resources on instructions/workflow to produce microtutorials, let’s find these and pool into a cluster resource

* Renee - Virtual Field Project: OBFS organization for biological field stations, has NSF grant for virtual field trips for their field stations and sites to expose students to different ecosystems

* Consider ways to include accountability for intellectual property, aspects of authorship

{in the chat: So are we talking about a curated list? Or our own videos? -> both are being considered}

* How to motivate researchers/technical experts -> CV items, elements of peer review? Items deserving of recognition, producing digital products within the scientific community

** Megan - “Credit for non traditional contributions and roles”

* Youtube videos have commercials - downside for instructional/informational video

** Megan - Alternative platforms, means to getting a doi: https://casrai.org; CRediT - Contributor Roles Taxonomy but not a place to view a resource

* Concept of “Folksonomy” - allow people to tag their own items

* Megan - “Also consider talking to the Data Management Training Clearinghouse - maybe inviting Karl Benedict or Nancy Hoebelheinrich in. Both would probably have a lot of thoughts here.” 

* John Porter - SCIVEE.tv used to be a YouTube-like site aimed specifically at scientific presentations, worked well but vanished one day when the funding ran out
  • ESIP Summer Meeting, Envirosensing Session
* Open envirosensing session - what are you doing/excited about? Need speakers

* “Half baked” / Ignite concept - 15 min talks, flash - 3-5 min talks

* There will be 90 min total for the session

* Cross cluster - Pull in speaker from your "nearest neighbor" ESIP cluster; possible Ag-Climate

Microtutorials and Oceans Best Practices

[Link to recording]

Attendees: Scotty Strachan, Kristina Fauss, Jay Pearlman, Matt Bartos, James Gallagher, Guy Lit, David Coyle, Renee Brown, Megan Carter, Christine Renee Gregg, Joseph Bell, Bar, Ethan McMahon


Announcements:

Joseph Bell is a new co-chair for the Envirosensing cluster.

Call for sessions for the summer meeting coming out soon.

Summer meeting will be virtual, likely July 19-23.


Notes:

  • Video Microtutorials
* Determine best practices on production from youtube.

* Cluster discussion, who wants to step up to take on some of the pieces to developing microtutorials?

Community driven topic - what do you want to do next?

Test cases, best practices, to implementation.

* MicrogranPs from ESIP could support this.
  • Oceans best practices - Jay Pearlman
* Presently working on a microtutorial for unbaited fish monitor - does it work, why does it work, what should you never do? - important to include "worst practices"

* Oceans Best Practices system: Way to foster quality control, consolidate best practice materials, open access

* Before recording, a promising method would have to be reviewed, accepted and deployed by multiple organizations within the community; ensures quality and consistency

Q across operations

Interoperabiltiy of data

* Data traceability and transparency

* Ocean Best Practices viewed as a repository from the beginning - under IODE, “Data Exchange” => ~1,200 best practices across oceans community, very broad from sensing to aquaculture

* The term "Best practices" can add a barrier to submitting -> “manuals” and “standard operating procedures” are more common terms

* Adding academic credibility -> peer review process and publication

* Ocean teacher global academy - training the trainer, working with established organizations, we don’t create the videos, we host them and make people aware of them

* No exclusivity, anything in the repository is open access

* Discovery of specific microtutorials may be easier on a specific site than youtube

* Expand into visual immersion techniques, CAD type designs -> giving tutorials in CAD/3d design

* Long term goal for a library of virtual training

* Concept for disk distribution in regions with low internet access
  • Questions?
* Renee - How is Oceans funded? 

** Jay - European commission grant Atlantis, NSF funding started the foundation, UNESCO present funder of operations and staff, tech development is done under grants; a lot of volunteer support

* Renee - Most of us do not work in marine environments, how do terrestrial systems work fit in?

** Jay - Newly acquired grant for Arctic expansion - sea ice, land, and atmosphere; could advocate a “land” best practice system as a cluster
  • Winter meeting recap
* Range of subjects to address through microtutorials

* Wide range of experience, capability, and focus represented in Envirosensing cluster

* Envirosensing has collective knowledge among members on how to make these microtutorials

* Need good metadata associated with videos to improve discoverability

Recording and Transcript of Session

ESIP Envirosensing Notes - 03/05/2019


Attendees - Scotty Strachan, John Porter, Matt Bartos, Connor Scully-Allison, Mike Daniels


Notes:*

Matt’s Presentation: Vehicles as ubiquitous precipitation sensors
The was a paper
What is the value of this?
Precipitation data is becoming sparse
Most sensors can only measure a point
The solution
One option is vehicles
They have sensors which can transfer data back
Windshield wipers as precipitation sensors
Study area was Ann Arbor
Map of single are trip shows a use case narrative and how it works
Use a video to determine the ground truth
Wiper Intensity does not significantly correlate to rainfall intensity
However wiper performs significantly better at determining the binary rainfall state
Produce a data product of combined radar and wiper data
Prediction performance was better than radar alone
Q&A:
Mike & Connor ask questions
Mike: How will you get data from Ford?
Connor: What was the computational intensity of this data synthesis? And, do you anticipate that this computation will scale well?
Matt: Its very computationally intense and may not scale well with more vehicles. It is easily parallelizable however due to the large time scales of the radar data
Scotty talks about the potential future viability of accessing and aggregating data from connected and smart vehicles.
Presentation session in ESIP Summer Session (Scotty and Connor will work on)
Deadline: April 26th

Recap of summer meeting
SensorDat update
Presentation: Cody Youngbull
SensorSpace: A Cutting-Edge Facility for Environmental Sensor Design, Prototyping, Production, and Deployment
Oldest continuously operating biological field station in the US
Montana underserved area; field station marine laboratories grants
Sensorspace
Four major areas: manufacturing, electronics, optics, microfluidics
Universities often do not have adequate electronics/optics shops. Sensorspace fills this gap.
Full-service; not just manufacturing.
Cater almost exclusively to ecologists. Build prototypes.
Lower costs for nonprofits/academia
Help write grants
Electronics: Make custom low-power boards.
Optics: Sondes, Dissolved oxygen, dissolved CO2 sensors.
Instrument considerations: e.g. vandalism-proof; shotgun-proof enclosures.
World's only continuous-flow digital PCR machine.
Digital-droplet quantification: instead of a analog detector, use multiple binary detectors.
Digital-droplet quantification enabled by microfluidics: can create tiny droplets, then count presence/absence of analytes in each drop.
Making environmental sensor networks summer course.
Setting up a LoraWAN sensor network

Scotty: Ongoing trend, sensor development and sensor explosion. What are you teaching students about best practices for documenting site conditions and managing data?

Jane: Do you open-source your sensor designs? Cody: Yes

John: What is the "ideal student" for your summer course? Are you looking for advanced graduate students? Faculty? Cody: Yes, we need faculty. Contact me.

Mike: Which IoT platform are you using? Are you deploying to things like standards, controlled vocabularies and ontologies for metadata, variable naming, etc.? Cody: MySQL, node red, grafana.

Mark: When will the DO and CO2 sensors you're developing be available for purchase? How can we find out about it? Cody: In beta stage currently. Under $1000 for both logger and sensor. Beta list is open. How to do this? Set up an external company (LLC) with a research contract. Transfer 100% of profit to university.

Envirosensing Summer 2018 Meeting Planning

ideas on what they would like to see us do
Additional standards
two IOT protocols
LWMQM and Coapp
Coapp very compressed data transmission protocol
Standards for manual user corrections of data
corrections and or annotations
without necessarily changing the data itself
markup language for manual user corrections of data
ways to annotate at the data point level
richer way of annotating individual data points
could be done with SQL or in NOSQL database
how does this relate to theme?
Automated quality control
broader category of data quality
CSSI elements to frameworks
standardized containers for QA and metadata capture
e.g., for iButton network
pass on to level 1 automated QA tests
simple, not as complex as GCE toolbox
help prepare more reliable datasets
Scotty working on proposal
would sensorML be helpful for ingestion
Mike also working on JsonLD extensions for real-time data sources
outline region - get summary of operational sensors, sampling rates etc.
How does jsonLD compare with sensorML?
schema.org used by google for finding related items
want to extend to data searches
json LD stands for Linked Data
schema.org relatively small set of ways to link data
would need extensions for handling datasets
in EarthCube focuses on data centers
working in new proposals on going to parameter level
Janet - sensorML is more content-rich
very broad!
want to extend work to come up with profiles manufactures can populate
archiving real time data
how often to update in portals etc. - best practices
connecting real time streams to archives
data descriptors for quality assurance and control
could we have a session on that topic?
what standard does (or doesn't) do for sensors
what are best practices, recommendations for new users
who would like to volunteer to talk about standards - metadata interoperability
would be good to hear about Coapp and ISPO
constraint application protocol - COAP
IPSO protocol for describing connected things including actuators
may not be mature, but has large user base...
very limited vocabulary for sensors
metadata capture, quality control, reporting quality control process
existing standards or new needed?
Smart Cities community is not yet at this point in terms of data interoperability
interested in monetizing
we have something to offer them
SWEET ontology - link to sensors not clear
Socioeconomic Value theme?
often collect data for specific purposes
but additional value may come from use by others
or could lead them wrong if metadata not complete enough to explain what has been done
getting better handle on collection of metadata
cautionary tales - what happens if we DON'T have the right tools for metadata
SNOTEL temperature data is a major cautionary tale in this way - Scotty
documentation is all manual
Smart Cities is huge socieconomic impact
tie to events
floods in Boulder  - models underestimated water content of clouds
Feedback on robust data corrections might be an interesting project (ties in above)
don't have good ways to track transformations could have one session more on annotation standards and another more on QA/QC
could be two complementary sessions
workflows then annotations and standards
if you are correcting data by adding offset, that is QAQC thing....
some drone folks think existing metadata standards are too onerous - perhaps
better to have big "bag of words"
more flexible standards
how signal processing techniques can uncover structure from unstructured data
e.g., Latent semantic indexing with frequency composition
similar idea, but for metadata
document, key values
could do a good presentation on that - but wear "mad scientist" hat....
hard to fit things in in field
there is ESIP funding for speakers in breakout sessions - not sure how to get that!
would be good to get Kirk to one of these sessions
have until the end of the month to do this
being part of ESIP governance helps
cluster can propose serial sections
QA workflows
metadata standards (and unstandards)
Scotty will put together and send to email list
would not mind 10-15 min per talk sequences with extended discussion
short presentations are good to start with - ideally WITHOUT conclusions
focused talks on specific standards
Can put directly into web site - long time to edit

Presentation

Virginia Coast Reserve LTER
Data collected by individual researchers; metadata ingested; automated sensors
Weather station: combination temperature, humidity, wind, rain.
Several tide stations using radar. Shared in real-time with NOAA.
Ground water monitoring station
900 MHz IP, 2.4 GHz WiFi
Major stations: Broadwater tower, Machipongo station
Archiving and publishing data:
Level 0: raw data
Level 1: processed data
Level 2: value added data
Data collection: PC with LoggerNet to Unix Computer running SAS/R
Something missing from automater QAQC: user corrections/flagging (e.g. tipping bucket clogged).
Right now, hand-coded php with forms for user input.
User input entered into a database that can be queried.
Code to implement user corrections automatically generated (e.g. using R code)

Questions

Felimon: any documentation on how you do QC?
John: Documentation is the actual code template used to do the post-processing.
Felimon: Look into QARTOD for how specific variables should be QAQC'd: https://ioos.noaa.gov/project/qartod/
Don: Campbell, John L., Rustad, Lindsey E., Porter, John H., Taylor, Jeffrey R., Dereszynski, Ethan W., Shanley, James B., Gries, Corinna, Henshaw, Donald L., Martin, Mary E., Sheldon, Wade M., Boose, Emery R (2013) Quantity is Nothing without Quality: Automated QA/QC for Streaming Environmental Sensor Data (Pub. No: 4825, Journal Article)
Mike: Does user QAQC require people to be constantly checking the data?
John: User input usually a result of checking on the equipment.
Mike: Do you use controlled vocabularies, etc.?
John: Generally not. Many stations go back to the 1980's. Some stations have these vocabularies, and measurements from other stations are tied to these.
Corinna: @Felimon: Are you working with NCEI?
Felimon: Yes, we do upload to NCEI.

Introduction

Recap of winter meeting

About 20 participants, from organizations including CUAHSI, EPA, etc.
Talked about sensor data workflow.
Gave survey on sensor data workflow.
Is this survey a useful product?

Comments on survey

Renee: In favor of distributing to a broader audience (LTERs, LBFS).
Renee: Few people using trusted repositories.
Mike: CHORDS trying to make use of trusted repositories more accessible.
Renee: Everybody is using different solutions. What's use in developing own solutions, as opposed to standards?
Corinna: DataONE is not a trusted repository; it is an aggregator.
Corinna: Coming up with a data model that works for everybody is too ambitious. Sometimes prevents people from properly using them.
John: Why so many solutions?: scale and resources, similarity of objectives, things change very fast.
John: As for vocabulary, scaling can be an issue. Process can become very difficult if number of terms is too large.
Don: Are we seeing any commonality of approaches?
Don: Were we supposed to be identifying bottlenecks in the survey?
Scotty: Some bottlenecks include: QC flagging process. Import configuration process. Overall development of modified data model.
John: Possibly only use a subset of the survey as a planning tool.
Scotty: Could be useful for a team of, say, civil engineers who are trying to write a proposal and figure out what tools they need. Most will not be thinking of trusted repositories, e.g.
Mike: In NSF community, more emphasis on taking more data and more measurements, as opposed to what is done with those measurements (are they well-documented, etc.).
Corinna: Don't give as many choices on survey, may be to constraining. PI's won't be planning at this level of detail, e.g.
Aaron: The more generic a tool is, the harder it is to learn.
Conclusions: trim down diagram to get rid of specifics. Focus on general technologies used.
ODM seems to be taking ODM in a lot of new directions---goal of end-to-end sensor data management?
Corinna: could be too broad. Hard to get data in, hard to get data out.
John: Standardized response blocks. Smaller number than in current survey.
Headers instead of diagrams.

Discussion of plans for the winter meeting

Scheduled a working session for the cluster with John Porter
Use this session to sit down, talk about workflows for end-to-end sensor data management
Everyone will hopefully have a cross-section of where high-performance/gaps in performance
Don: See what software people are using in the field, what loggers are used, how data is sent back to base station?
Scotty: Have a system diagram available for everyone to show their workflows and see where they can use particular tools.
Paul: Is the working session going to be interactive?
Scotty: Depends on how many people show up. If there are 20 people, e.g., have a brief synopsis, have an exercise in which people explore different architectures and see how their workflow fits in.
Else if there are very few people, go around and describe for each user.
Don: Have you described that in the abstract?
Scotty: we kept it general.
Don: We should say "attendees should come prepared for participation"
Scotty: Concurrent with OGC, metadata carpentry, earth data science analytics, valuables consortium session (and one more)

We we should do this next year:

Alternating monthly phone calls:
(i) cluster work, potential publications
(ii) Guest speakers present 20-30 minutes on an aspect of their research
Mature workflows
Completely different workspaces. Preferably earth sciences, but different.
Renee: Would like to see NEON again.
Scotty: Celeste had sensor network destroyed by wildfires (had insurance); would be interesting to see how they rebuild it.
Renee: What topics would you all be interested in?
Don: Touch base with the group and see if they have any updates.

Other things:

Jane: How does the winter session fit into the FAIR data concept.
Scotty: Look at how well workflow fits into the FAIR concept. Large strategic impact is FAIR concept; tactical focus is how to do you manage increasing volumes of data with decreasing person-hours.
Jane: OGC will be at this winter meeting.
Scotty: Many groups are using a modified ODM CUAHSI data model. Similar to what Jane is using.
Jane: Can likely find speakers in RDA groups.
Don: Sustainable data management group has an ESIP wiki with notes on FAIR data.

Skip January telecon; reconvene in February.

Preliminary remarks
senior project on CHORDS at University Nevada Reno
Continuation of discussion on cluster goals: summary
Time to start summarizing key software tools, seeing how they can fit together and where the gaps are
If someone has to spin up a new sensor network from scratch, how could they use a set of tools to streamline the process
How to have information be interoperable?
Submitted a working session to the ESIP Winter Meeting
To plan for taking first step forward over the next couple years
Co-organizers are Scotty and John Porter
Renee stepping up to be a new co-chair for the Envirosensing Group
What would you suggest to a brand-new network manager on what they should do, what tools should they use?
Literature review for each of the main boxes
Corinna: most interesting part to talk about are the arrows.
Define what the arrows represent
How many arrows could sensorML satisfy?
More MLs than sensorML:
WaterML, EML
Data Turbine as a vehicle?
Where would it fit in, does it fit in?
Hasn't been used, because Campbell provides all the services in the management interface.
Has anyone done a study on how long it takes to set up and configure a sensor data management system?
There are some aspects of QC that can slow down transfer of streaming sensor data to the database
OGC SOS and OpenSensorHub handles many of the things on the diagram
Ethan McMahon: Is there a general diagram?
http://im.lternet.edu/resources/im_practices/sensor_data
http://im.lternet.edu/node/963

Take homes:

- Scotty: the Cluster needs to define a topic objective with specific goals for the next 1-2 years. We have been spending most of our effort looking at software tools and workflows for sensor network scientists and managers. We could detail some of this, enhancing the resources already available in the Best Practices. Our goal should be to reduce IM time spent on managing data, to increase scalability and focus more on quality. Streamlining the setup/config/monitoring processes is key, while including community standards and external connectivity.

- Updating a workflow model graphic would give helpful guidance, modify Scotty's?

- Matt: a literature review of each sector of the workflow (tools, practices) would be very helpful, and we could add those to new Guide documents.

- Corinna: the challenge is in defining what the flows between software elements consist of (formats/contents/sizes/standards). The group could spend worthwhile time on that.

- Matt: SensorML as a primary communications medium between softwares - how much does it already cover, and could it use improvement?

- We could take a "use case approach", where as an exercise we have IM's fill in the blanks on a model graphic with their solutions, highlight the bottlenecks, and make suggestions or wish lists. - Felimon: we should have a presentation by 52north, they may have solved many of these problems or have good component solutions?

- Other resources to explore as we set up this topic: OpenSensorHub, SensorML, EML, WaterML, OGC-SOS (standards)

Intro - Scotty
software framework for data management
working on proposal
but could have community projects
diagram shared by Scotty
where does FRAMEWORK fit in - dashed line
into structured database a la CUASHI
GCE toolbox example of stand alone software
description of diagram
interfaces to sensor systems
database structure built along community standards
metadata and data proceed in parallel
harkens to FAIR principles for data management
discussion
definitely worthy of groups consideration
interested in relation with OGC and sensorWeb
Corinna input?
I was hoping Jeff would jump in, he's done most of this from the CUASHI perspective
EDI can't do all of what is in diagram
more interested in matchmaking
want as modular as possible so we can insert expertise into particular areas
Jeff Horsburgh
knowing what we've worked on
many pieces worked on as open source
utility is variable
community to work on them would make it better
discussion
still a gap , hard to spin up CUASHI software
database structure & standards - should follow what has already been done
worthy goal to pursue?
is this thinking too big for the cluster attention?
Two questions
some providers take the lions share of IOT platform - Azure, Google, IOT etc. role in providing interface for embedded devices
what external connections would you like to integrate with
open question
could use a wider array of definitions for inputs
brining in metadata from a community should only require setting up once
include built-in test cases - automated continuous development process

might be best to make end-to-end system work with most popular systems real-time applications

probably not - in external connections is near real time
lessen work for IMs etc.
or focus on practices
GCE toolbox actually covers a LOT of this ground
but built on top of Matlab
specialized metadata
can use some "lessons learned" from it
as Corinna said, would like to see modular with well-documented interfaces, perhaps as web services
could go "box by box" for discussions of what is needed and what is already working
develop some use cases
develop cluster goals
need to focus on interface/APIs between boxes
that allows others to build code on either end independently
Like modular approach - talking about process boxes
AND uses diverse software as processing
Loggernet to GCE Toolbox to CSV to DB
could fill out - broaden input
identify and move forward on generic pieces
XDOMES at Winter Meeting - will this topic be discussed there
want outreach to make a larger group available
would have no problem proposing session at winter meeting
we know how to do this as individuals - but tools for new person don't exist yet
would be good to leave some blank boxes in framework and let others fill it out
modularity sounds good - importance of pieces varies between groups
would like a plug-and-play framework
overlaying pieces on framework would identify holes and what plays well together
Would like both higher and lower level documents
need to communicate with managers and programmers
Next call
run through ideas on how data flows from place to place
identify places where other boxes are needed

Introduction

CHORDS: Cloud-hosted real-time data services for the geosciences

Real-time data is of critical and growing importance in the geosciences
Necessary for hazards like floods, earthquakes, etc.; but also field experiments
Enhances rates of data transfer from the field will improve data quality and research outcomes
Organizations like NCAR have great real-time visualization tools, but the data are not easily accessible
Small research teams are taking valuable measurements that could also be of broad benefit
However, these data often aren't accessible to the broader community
Case studies:
Studying evaporation in the great lakes
Using infrasound to detect severe weather
Volcano monitoring in Tanzania
Crowdsourced real-time data helping to measure and predict earthquakes
Web of sensor data can be challenging to manage
Varying spatial scales, flags, metadata
Most scientists don't want to spend time reading standards
Enter CHORDS
Chords emphasizes simple ingest and access to real-time data
Meant for scientists who want to spend time doing science rather than managing data.
Can be set up using Amazon Web Services by a lay-user.
Data is pushed using simple HTTP GET requests.
Live demo of portal
Implementation details
SensorML used to register each site.
Data fetch via geojson, csv, etc.
Data stored in influxdb, MYSQL used for metadata

Matt Bartos - Wireless sensor networks for smart water infrastructure

Overview of research efforts underway at the University of Michigan Real-Time Water Systems Lab.
Description of wireless sensor node hardware and data backend.
Two ongoing applications:
Using wireless sensor networks for real-time flash flood monitoring in the Dallas--Fort Worth Metroplex.
Using wireless sensors to optimize stormwater quality via automated control infrastructure in Ann Arbor, MI.


Janet Fredericks - Update on XDOMES

Current efforts
Overhaul so users can create re-usable models of sensors with rulesets.
Release of sensorML editor ongoing.
Goals for cluster
Create vocabularies that manufacturers can reference (e.g. sensor types, observable properties).
Sensor vocabularies should be domain-driven rather than manufacturer driven.
Remove ambiguities in vocabularies (e.g. beam strength vs. sensor strength).
Identify some example cross-domain sensors.
Immediate goals
By March meeting: Have sensor types and observable properties.
Make spreadsheet (SensorType and ObservableProperties) a google doc that is linked to from envirosensing page to invite more community participation.

Plans for next telecon

Doodle poll to set time for upcoming meetings (effective April).

Notes:

Discussion of what is needed from community to enable semantic and syntactic interoperability

Sensor manufacturer responsible for making OEM model description
creates a unique identifier for each sensor
SensorML file is created and belongs to sensor owner
Data managers describe processing that's done
Documents reference terms that have meaning --> reference ontologies
Hoping to get community to help with development of ontologies, esp in communities Janet isn't a part of (i.e. not in oceanography comm'ty) -- then Janet can work with sensor manufacturers to reference those terms
Recorded presentation includes example ontology form; Wiki reference links should include date accessed
MMI ontology registry has a big vocabulary database
Can create new vocabularies and map to other known ontologies
Watch the video of the telecon for more information about how this works

Scheduling an informal lunch/coffee meeting at AGU in San Francisco (all)

Scotty added Janet's presentation schedule to his schedule for the meeting -- contact either of them if you want to meet up with them
Janet will send out this message to everyone

Next meeting (2/6/17)

Vasu and Janet talk about engaging sensor manufacturers

Notes:

Change in leadership

Scotty Strachan to begin co-leading EnviroSensing group with Janet Fredericks
good time to change leadership, Don is retiring soon, time to think about new directions (XDOMES? other projects?)
Matt Bartos (U Michigan) will take over as student fellow (Alison is done at the end of the year)

Discussion of new directions

Don - short recap of history of EnviroSensing cluster and original mission
this is review from previous telecons--see past notes
Janet - update on past year of work on XDOMES
ES group mission and goals is well-aligned with her work, but she needs people to participate rather than just be an audience for the work they're doing
e.g. looking for vocabularies... need this before can go to sensor manufacturers
having difficulty getting people involved -- need folks to participate!
no ES explicit presence (i.e. no specific sessions) at winter meeting, but intend to have a session at summer meeting
Don suggested more explicitly crafting this as a clear opportunity/desire to get people involved
good to tie to specific time frame, task, or event
Send out info prior to telecon, have people look at it and prep something specific, then discuss on telecon
maybe try to target specific people - perhaps folks can help ID who these people would be
follow-up meeting next month to try to get volunteers to describe sensors (spreadsheet?)
plan to have an informal ESIP/EnviroSensing get-together at AGU?
would be great to have a few volunteers, work up to people doing talks at ESIP Summer Meeting?
spend some time together talking about what this is, catching up on the cluster, etc.
Scotty - some thoughts on future directions
excited to step in and help out with the group, since it's been very helpful to expand his data management world
completed PhD over the summer, things are currently a little hectic--transitions, etc.
focus on field designs, esp. on mountain environments
could do multiple projects at once--would be good to stay focused and help the XDOMES project

Notes:

Janet Fredericks on Q2O web service
Using SWE to bind metadata to observational data - enabling dynamic data quality assessment
Background: NOAA-sponsored project to address data quality in sensor web enablement frameworks

Janet walked participants through the Q2O (QARTOD-to-OGC) web service implementation to demonstrate how web services are used to describe processing, select and describe data and offer it to a user as a service.

OpenSensorHub

open sensor access so that people can discover sensor data, etc.
geolocatable/geospatially aware, fully described data, sensors, and processing
free open source software on github

SmartCity Air Challenge

Ethan: EPA is putting out a challenge called the SmartCityAir challenge: ask communities to tell them how they would deploy a large team of air sensors
provide seed money, etc.
groups have to describe how they would monitor and manage the data, deal with sensors throughout their lifecycle, do this sustainably…
gov’t learning what practices work best
will be announced formally next week; Ethan will send a less formal paragraph out to this group
interested in ideas for how to get word out about this, how to encourage people to use best data management practices that exist
focus is really on the data management side

With XDOMES and OpenSensorHub → trying to get all of that kind of knowledge (how it was used, description of data, etc.) so that you could have people throwing sensors out and have access to that data

Summer meeting:

Janet will be sending out an email about preparing for the workshop at the summer meeting → people can let Janet know that they’re coming
At Thursday session hopefully Janet, Mike, and Vasu will all be presenting
Maybe talk about whether we want to reach out to a broader audience? Janet would like to know how many people plan to attend the workshop
Poster? Don says we did one last year and could just substitute some of the stuff on there with summary points of what we’ve done this year on our calls -- Don will produce the poster if Janet sends summary slides from some of the talks to him

NO call in July -- we’ll just see each other at ESIP! Next call will be in August.

Notes:

Mark Bushnell – Quality Assurance and Quality Control of Real-Time Ocean Data (QARTOD):

QARTOD manuals: focus on real time, usually coastal (http://www.ioos.noaa.gov/qartod)
Includes quality control tests and quality assurance of sensors (in an appendix)
Discussion of operational vs. scientific quality control and different needs/contexts for each
Board meets quarterly to review progress and identify next variables (if you have ideas for variables, let Mark know!)
Each manual takes 6-8 months and each one is a living document that is updated
26 core variables
next up: phytoplankton species!
Discussed an example test from the waves manual
Five “states” for data qc flags (pass, not evaluated, suspect or of high interest, fail, missing data)

Discussion & Questions for Mark:

How to handle flags that represent a mix of semantic notions? Hard for data consumers to understand (what’s the actual problem?)
What about showing (or not showing) data that doesn’t meet a certain standard?
If you’re looking for extreme events, for example, you might want to see all the data…
Helpful to have the option to see all the data (if you’re an operator, say, you might look at failed tests for an instrument)
Best to let the data user select what level of quality they’re interested in
For EnviroSensing, is there a place to save/share code for QC tests?
Not at the moment
Would be good to start tracking/storing code for tests that people do somewhere and have a DOI that describes the processing
python codes for the implementation of the QARTOD recommendations is at https://github.com/ioos/qartod (also look here --> https://github.com/asascience-open/QARTOD)
Core link in email from Janet (body copied below) -- many other pages and additional information can be found from that link
Background: The U.S. Integrated Ocean Observing System® (IOOS) Quality Assurance/Quality Control of Real-Time Oceanographic Data (QARTOD) project has published nine data quality-control manuals since 2012. The manuals are based on U.S. IOOS-selected parameters (or core variables) that are of high importance to ocean observations. The purpose of the manuals is to establish real-time data quality control (QC) procedures for data collection for core variables, such as water levels, currents, waves, and dissolved nutrients. The QC procedures provide guidance to eleven U.S. IOOS Regional Associations and other ocean observing entities, helping data providers and operators to ensure the most accurate real-time data possible. It began as a grass-roots organization over a decade ago - the background can be found on the IOOS QARTOD Project website: http://www.ioos.noaa.gov/qartod/welcome.html

There's similar work at http://www.iode.org/index.php?option=com_oe&task=viewDocumentRecord&docID=10762
Tad Slawecki (tslawecki@limno.com) heads the informal QARTOD Implementation Working Group and posts minutes at https://docs.google.com/document/d/128xPGjTMBP9FC-SEg9vGe8bD145LGdapH21WV5smzn4/edit

Minutes:

Best practices work:

Post a citation suggestion on the introduction page of best practices? Maybe also a snapshot PDF that folks could download with a citation?
People DO go to this page, says Scotty
Mountain Research Institute (MRI) is doing some work trying to write best practices, would be good to try to get them to use ours rather than create something entirely new…

Future of EnviroSensing cluster:

Just need to have one vision at a time--for now we can stay focused on the XDOMES work
Scotty wants to continue to stay involved, promote cluster and its work a bit more to folks after finishing up his PhD (soon!); would be interested in taking lead in cluster after that, too

Future meetings:

Mark will present material on real-time quality control that was planned for this month on the next call instead, due to low attendance on this call
Would be great to reiterate that we didn’t start as ONLY LTER--the best practices doc had input from other folks too--and that that isn’t where we have to stay, either--we can continue to incorporate other things/groups
Janet will talk about summer meeting workshop plans on June call: registering vocabulary
will be a good workshop for beginners/people who need to be introduced to the concept
Summer meeting (July): have a 1.5-hour session for EnviroSensing--should email asking for folks to present

Minutes:

1. Future meeting ideas (Don)

Revisit best practices--have folks present the chapters they did and rekindle interest; Scotty said he’d be willing to do this for his chapter
Email Alison at alison.adams@uvm.edu if you have ideas for future telecons!

2. Summer meeting -- session/workshop ideas? (proposals due at beginning of April)

XDOMES workshop: connected to EnviroSensing cluster?
sensor provenance EnviroSensing breakout session?
Janet to lead more hands-on workshop on Semantic Web, etc.?
Let Alison, Don, or Janet know if you have additional ideas

3. Update on work plan draft (Don & Janet)

Conversation with Erin last week
If you might like to be the next leader, let Don know--thinking of having an “on deck” leader position
Interest in AGU Geospace blog? Lots on data use, etc. This could be a place to put out info about our cluster

4. Rotating chair position for Products & Services (Alison)

Right now, Products & Services does three things: (1) FUNding Friday, (2) the P&S Testbed, and (3) tech evaluation process with NASA AIST to evaluate AIST-funded projects. Also working on an evaluation process for the projects funded through the testbed, and would hopefully provide this to the Earth science community at large eventually.
P&S wants to have a rotating co-chair position; would last for three months and would be a rep from a different committee. The first co-chair (starting in April) wouldn’t be involved in proposal evaluation/selection, but would be involved in ideas for student/PI matchmaking and mentoring for FUNding Friday and the evaluation and testbed activities. It would be a great opportunity to learn more about P&S and have them more about us. It wouldn’t prevent you from submitting a proposal to the testbed.
If you’re interested, email Soren at sorenscott@gmail.com; you can sign up for the rotating co-chair position here

5. XDOMES team on Semantic Web (Krzysztof Janowicz)

Full recording with slides available in recorded meeting
Semantic technologies can improve semantic interoperability
More intelligent metadata, more efficient discovery, use, reproducibility of data; reduce misinterpretation and meet data requirements of journals, etc.
Large community in science, gov’t, industry; many open source and commercial tolls and infrastructures; there are existing ontologies and huge amounts of interlinked data
Move the logic OUT of software and INTO the data
Semantic technologies support horizontal as well as vertical workflows
Semantic interoperability can only be measured after the fact bc meaning is an emergent property of interaction; come up with technologies that prevent data that shouldn’t be combined from being combined
Discussion:
How much of this is already in use or is this just setting up the platform at this point?
With XDOMES we are at an early stage, but in terms of the infrastructure, a lot of it is already productively used

On the agenda:
Janet on XDOMES
What should EnviroSensing cluster do?

XDOMES (Cross-Domain Observational Metadata Environmental Sensing Network) NSF project funded as part of EarthCube

  • cross-domain observational metadata
  • focusing on: sensor metadata creation, data quality assessment, sensor interoperability, automated metadata generation, content management
  • 4 types of work (funded for two years)
    • software development to create Sensor ML Generators and registries for semantic techs and Sensor ML documents
    • Trying to engage people like this community, sensor manufacturers to create a network of people interested in promoting adoption of sensor ML techs
    • Useability assessment
    • Integration of semantic interoperability
  • this project is about capturing metadata at the time of CREATION of the data
  • GOAL: put out metadata automatically in interoperable ways (community-adopted, standards-based framework)
  • use of registered terms to enable interoperability
  • can also help manage operations by providing standardized information about how sensors were configured, etc.
  • want to develop community within ESIP who will follow and promote this approach
    • vet, look at usability assessment, what do you want us to do and is it useful to you?

Discussion

  • Vasu says this is related to things EPA has been working on--excited to continue the conversation
  • Jane asked about communication with sensor-creators so this can be implemented in new sensors; Janet said that isn’t part of the project at this point
  • Potential application for folks with Alliance for Coastal Technologies--they work on sensor validation and I think it’s a slightly different take, but this is definitely something they could benefit from (like if we start describing our sensors in a way that the information can be harvested)
  • If people are interested you can see what Janet is putting in the file and think about whether this would be helpful or useful or whether she’s missing something; would you be willing to test this in your own environment?
  • Delivering data is kind of beyond the scope of the XDOMES project at this point
  • Vision: info is out on the web, and you have an app to go and harvest the information that you need
  • Do we want to work this pilot project into public presence in this cluster?

Future WebEx ideas

  • Could do a WebEx on how water ML, sensor ML, etc. fit together
  • Janet is approaching Krzysztof Janowicz to discuss sensors and semantics with us on the March call

06/22/2015

Today we had Dave Johnson from LiCOR Environmental speak with us about eddy covariance. We had a large group of attendees.

Dave shared with us links to the LiCOR software [3] and a book [4]

  • The problem they are solving is that the data coming in with eddy covariance is high resolution and large, more than 300 million records per year.
  • They were able to put much of the processing and QC logic into the SMART system, which is on the instruments in the field.
  • An eddy covariance system can "see" about 100 x its height above the canopy.
  • We were interested in the possibilities for real-time data qc, and also how the information can be transferred between the instruments in the field (i.e. cell modem, line, etc.)

02/24/2015

Today we had William Jeffries from Heat Seek NYC talk to us about his platform for civilian monitoring of home temperatures in apartments using low-cost sensors and wireless mesh networks taking hourly readings.

Attending the call were Fox and Don from Andrews, Josh at UM, Jason in Fairbanks, Becky from Onset, Ryan from UT and Scotty from UNV as well as some listen-in callers.

  • Heat seek NYC has nodes containing up to 1000 low-power, low-cost thermometers which are mapped to custom printed circuit boards. The software stack is Ruby on Rails with a Post-Gres backend.
  • HSNYC focuses on sensor network's ability to affect and effect policy, and so far has seen that the government views sensor networks as a cool solution to a lot of difficult regulatory challenges. They provide reliable information that officials and citizens can use with printable, court-friendly PDF's.
  • Funding is by kickstarter and was started by the NYC Big Apps campaign, a giant Civic Hacking Competition.
  • They have been incorporated as a non profit in NY since 2014
  • First sensors were Twine Sensors off the shelf temperature sensors; not so good

stale data

  • Now they make their own temperature sensors, using a push system instead of a pull system. (if there's a problem with the system just don't get pull out of it.)
  • We asked about LCD and the reason for not implementing is that many tenants aren't actually as interested in the data as the response from the policy makers
  • Some people will abuse the system so they use tamper evident tape and photos of installation to protect ; landlords have financial incentives and there can be intentional lack of repairs
  • Local cache-ing of the sensor occurs; sensors cache at the hub, relay server that sends back
  • There are several levels of caching, and also well as flash memory on the XP radios
  • A key question was is there a long-term storage that is a local cache? We don't have a solution either
  • We had interest in a company called H20degree
  • For QC they do indoor and outdoor temperature comparison, comparing the sensors to one another and to store bought sensors before and after installation...
  • Frequency for radios/caching is hourly waking up point data
  • We are all interested in a low-or-no power source/ transmitter, maybe based on raspberri pi
  • need a high peak power envelope-- transmission needs to deal with being fairly far apart... implementation needs to come online and transmit an awesome signal for a short time and go back to sleep.

Note on Webex recording: I am going to check into the recording- my system claims to have been recording but it is nowhere to be found (Fox)

01/27/2015

Rick Susfalk from the Desert Research Institute presented about Acuity Data Portal. Notes from meeting taken by Fox Peterson, please edit as you see fit.

We had in attendance 8 persons.

Acuity Portal System

  • Started in 2006
  • originally VDV data solution
  • improvements to web-interface; sits on top of VDV as Acuity server
  • Acuity is a continuous monitoring of key client-driven data
  • it includes sensors and data logging deployment and maintenance, telemetry, data storage and analysis, automated airing, web portal for data access
  • individualized web presence tailored to client needs
  • not a single tool, but instead integrates commercial, open source, and proprietary hardware and tools
  • customizable project specific descriptions
  • common tools used to provide rapid, cost-effective deployment of individualized portals
  • physical infrastructure is shared amongst smaller clients for cost-saving or it can be segregated for larger clients.
  • access is controlled down to the variable level-- "we can define who gets to see what"-- for example, public can not see some features
  • one view could be "pre-defined graphs" without logging in, but if you want to download the data you must log in at your permissions level

SECURITY


ANALYSIS

  • customized thresholding and data-freshness
  • trending alerts, for example, know if battery will go bad
  • stochastic and numerical modeling
  • scoring incoming data for QA/QC processing

QA/QC tools

  • web-based GUI
  • users and managers can create, edit, and modify alerts online
  • groups can be created so that you can schedule management and alerts
  • also offers localized redundant alerting
  • two-way communication with the campbell data loggers (cr1000)
  • more about getting the data to the data managers for more in-depth QA/QC than about providing that part of the tooling

Data graphing features

  • Pre-determined graphs for basic users
  • Data selector for more advanced users
  • "we don't know what the users want to see so we give them the tools to do it" (good idea!)
  • anything you can change in Excel you can change in their graphs on the website -

Links

Metadata

  • relates your parameters to the network and what other sensors are doing
  • current system is getting more flexible
  • metadata is still largely user responsibility

Flight plan - safety tool

  • field personnel are data
  • users put in the travel time for safety
  • buddy system, alerted right before you return, then calls boss etc. Many levels hierarchy

Demos

  • Portals that are monitoring things
  • ability for data refreshment
  • colors for indication, ex., data would not be gray if there was lots of new data
  • users can change the settings on the data logger
  • scrolling, scaling, plotting, etc. via interaction with the user
  • can save your own graphs

graphs and alerts

  • many parameters
  • you can save!
  • email, sms, phone
  • default settings for users
  • lots of personnel management tools in this in general
  • cross-station "truly alarm or not" if station1 has a value but station2 has a different one, don't alarm sorts of rules
  • lists/user groups appear to be very important with this tool
  • sensor and triggers: customize one or more parameters that you are bringing into your database

real-time updates on loggers

  • ex. 10 minute data, user comes in and makes a change, the information is saved to the database and then is presented to all other users
  • the person will request a change and say what that change is
  • when there are different levels of connectivity ie. analog phone modems, before the data has the chance to work its way back into the system there is a lot of validation being done

example

measurements/metadata

  • extends beyond the vdv, more than 1 .dat file
  • integrate multiple .dat into many tables
  • managed by the data managers at DRI
  • workflow :

logger net --> vdv --> acuity, ok, let's give access to the DM for all these variables, click on it ok now the manager can see it --> generate an excel file with tables for all this metadata --> enter the data into the excel files--> send back to acuity --> injests, runs queries, back to db-- > metadata in bulk, quickly

  • we asked if the system ends before the qa/qc process begins, answer: qa/qc is done at the DRI, near real time QA though

future capability

  • direct the managers to the future data problems
  • manual decision making

Scotty asked about the duration (long and short term) of projects and how affects funding. most is funded by long-term projects; this is why they do the stats and numerical methods in the future

Amber asked about pricing; pricing is by hour to get up, then a price for maintaining the system for the duration of the project 5-10 .dat files, only 8 hours of person time at DRI to make a portal

10/28/2014

Wade Sheldon presented the GCE Data Toolbox – a short summary follows:

  • Community-oriented environmental software package
  • Lightweight, portable, file-based data management system implemented in MATLAB
  • generalized technical analysis framework, useful for automatic processing, and it's a good compromise using either programmed-in or file-based operations
  • Generalized tabular data model
  • Metadata, data, robust API, GUI library, support files, MATLAB databases
  • Benefits and costs: platform independent, sharing both code and data seamlessly across the systems, version independent as far as MATLAB goes, and is now "free and open source" software. There is a growing community of users in LTER.

Toolbox data model

  • Data model is meant to be a self-describing environmental data set-- the metadata is associated with the data, create date and edit date and such are maintained, and its lineage.
  • Quality control criteria- can apply custom function or one already in the toolbox
  • Data arrays, corresponding arrays of qualifier flags -- similar to a relational database table but with more associated metadata

Toolbox function library

  • The software library is referred to as a "toolbox"
  • a growing level of analytical functions, transformations, aggregation tools
  • GUI functions to simplify the usage
  • indexing and search support tools, and data harvest management tools
  • Command line API but there is also a large and growing set of graphical form interfaces and you can start the toolbox without even using the command line

Data management framework

  • Data management cycle - designed to help an LTER site do all of its data management tasks
  • Data and metadata can be imported into the framework and a very mature set of predefined import filters exist: csv, space- and tab-delimited and generic parsers. Also, specialized parsers are available for Sea-Bird CTD, sondes, Campbell, Hobo, Schlumberger, OSIL, etc.
  • Live connections i.e. Data Turbine, ClimDB, SQL DB's, access to the MATLAB data toolbox
  • Can import data from NWIS, NOAA, NCDC, etc.
  • Can set evaluation rules, conditions, evaluations, etc.
  • Automated QC on import but can do interactive analysis and revision
  • All steps are automatically documented, so you can generate an anomalies report by variable and date range which lets you communicate more to the users of the data

  • Fox Peterson (Andrews LTER) reported on QA/QC methods they are applying to historic climate records (~13 million data points for each of 6 sites).

The challenge was that most automated approaches still produced too many flagged data that needed to be manually checked. Multiple statistical methods were tested based on long-term historical data. The method they selected was to use a moving window of data from the same hour over 30 days and test for 4 standard deviations in that window; E.g., use all data for 1 pm for days 30 - 60 of the year, compute four standard deviations, and set the range for the midpoint day (45) at the 1pm hour to that range.
