< Back to | Workshops | Air Quality Data Network
Monday 16:00-18:00: Data Catalog Side Meeting (everyone welcome)
GI-cat - ESSI Federated Catalog (aka EuroGEOSS Discovery Broker, part of GEOSS Common Infrastructure)
AQComCat - Air Quality Community Catalog
GI-cat-AQComCat link - Federating AQComCat into GI-cat; Accessing GI-cat from AQComCat
Monday 18:00-19:00 Social
Tue 08.00-10.00: Self-Introduction, 5 mins/participant
Welcome
Logistics
Agenda and Procedures
- Daily 8:00-12:30; 16:00-19:00; Coffee break and 18:-19:00 (1.5 h) informal interaction
- Total of ten two-hour sessions.
- First half focused on data server, catalog software
- Second half on more general AQ data networking
- Two rapporteurs for each session
Self-Introduction - by each participant
- Slides 1-2: Name, institution, relevant research (on interoperability, networking), participation in major projects/programs
- Slide(s) 3-(4): What would you like to take away from the workshop; what would you like to offer to the workshop (or AQ CoP)
Tue 10.30-12.30: Introduction of Hubs, 5 min each
Intro of AQ Data Hubs - by their representatives
- AQ Community Servers: Common DataFed, FJ Juelich, NGC/CIERA, EBAS
- Other Servers: DLR/ACP, AIRNow, EEA NRT, AQMEII (AeroCom, RSIG, GIOVANNI)
Air Quality Community of Practice (AQ CoP) - R Husar
Air Quality Community Data Server - M. Schultz
Tue 16.00-18.00: IT Breakout: AQ Community server software
Use of netCDF and other data formats
Gridded data service through WCS
Station-point data service (SQL)
Data server performance issues/solutions; Server co-development tools
Relationship to other WCS servers; Real Data-to-WCS/WFS/WMS-Mapping
Notes
Tue 16.00-18.00: Scope and Type of Data to be Served
- Ensemble System (JRC) Presentation from Stefano Galmarini on AQMEII and ENSEMBLE (Data Hub/Facilitator)
- Witten in Perl and IDL
- Comparisons and evaluation of models
- Coordinated model harmonization across 27 models
- Also a reposition for the dissemination of model and AQ measurements
- Produced 4-page tech spec docs that were sent to groups for supplying data; this was key step in making the process smother.
- Main features
- Transfer of very large model output across internet
- Storage of 1,2,3D model data
- Quick access of large dataset
- Distribution of KML and WMS (in progress)
- Use an ASCII format file to describe the model files
- Have a program call ENFORM (Fortran) that transforms model data into the compressed dataset (1.2GB → 200MB)
- Can produce GE projected files (nice)
- 11 papers came out in a special journal edition
- Data Versioning. Aasmund brought up the issue of versioning. He suggested that timestamp of submission of data is a useful versioning approach.
- Need additional flags on observation level
- Latest time stamp requires to data ...
- Version dates could confuse broad range of users
- Martin - Applications would use the version date, not user
- Who are the next users in this chain?
- GEO AQ CoP. R. Husar begun discussion on what the AQ Community of Practice is/does? CoP Intro PPT
- Pic of data pool - started discussion with the idea that CoP should only create distributed data pool and build the data network.
- Discussion w/in group thought this was too narrow and had issues with how the CoP differed from the facilitators.
- Reworded CoP purpose to CoP should "Connect and Enable" AQ data networks, hubs and facilitators so that they can connect and enable the data needed for their systems.
Data Providers: Existing data Data Hubs - how do they work?
Data Classes
- by data source-driver (mandated, research)
- by content/platform (emission, ambient, remsens, model)
- by space-time (global, regional)
Data Level
- Primary (original), Secondary, Mediated
- Raw , processed , how?
Tue 18.00-19.00: General Discussion, with wine and cheese
Wed 8.00-10.00: Breakout reports, general server items
What few things must be the same, so that everything else can be different?
WCS_Server_Software#WCS_Server_for_Station-Point_Data_Type
Report from the IT breakout session: Community server software
Report from non IT breakout session: ADN scope, providers, users
Report from the pre-workshop Data Catalog side meeting
Crossover topics between IT and non-IT issues
Wed 10.30-12.30: Data network catalog and clients
Functionality of an Air Quality Data Network Catalog Who , what, where, when
Catalog content and structure (granularity) of ADNC?
Minimal metadata for discovery, data provenance, quality, access constrains?
Single AQ Catalog? Distributed? Service-oriented?, Access rights
- Ben: Similarity with hydrology
- Stefano: GI-cat - help on CSW implementation
- Paul: Catalog has to be linked to the data offering services
Catalog Clients
Wed 16.00-18.00: Relationship, cooperation, governance
3 call-in presentations, (10 mins each max!)
- 16:00 US EPA - Terry Keating (HTAP, CyAir..) ...perspective on AQ data networking;
- 16:10 Nat.Park Serv. - Bret Schichtel (VIEWS) on data collection & usage in VIEWS DSS -
- 16:20 GEO - UIC. Adam Carpenter on GEO Earth Observation Priorities
16:30-17:00 Discussion
17:00 - 18:00 User perspective, value chain.
Relationships, cross-thematic links (EGIDA, ESIP), How can we collaborate? Network governance
Wed 18.00-19.00: General Discussion, with wine and cheese
Thu 8.00-10.00: Networking impediments and opportunities
JJ Bogardi, Global Water System Project (GWSP) at EGIDA, Bonn:
Nature of Networking Projects: Complex funding; mixture of paid and voluntary; multiple obligations; international; differing project maturity; governance, cultures
Which glue keeps it together? Trust and personal affinity. Common objectives and scientific values. Mutual respect. Mutual benefit (win-win). Complementarity. Donor dictate
Lethal“ ingredients. Turf mentality. Budget discrepancies. Too much competition. Lack of data and information exchange. Donor jealousy
- Clear statements about obstacles: no clear structure; no dedicated funding and no clear idea(s) yet how to do it.
- Opportunities, fixes: ID manageable work packages; Find, organize, distribute reusable components, resources; Create win-win situation
Thu 10.30-12.30: AQ Community Metadata Discussion
- Target User communities
- Use cases for different applications... from scientists to managers, media people and the general public)?
- How can users find out about (each) system? Big future issues: data quality, traceability, metadata..
Thu 16.00-18.00: Workshop outputs, outcomes, plans?
What are the anticipated outputs? Agreement on community WCS server for grid and point data; server governance, distributed catalog; workshop summary
What are the anticipated outcomes? More servers and data added to the shared data pool and more willing users of shared data.
