< Back to AQ CoP.png | Workshops | Air Quality Data Network

Monday 16:00-18:00: Data Catalog Side Meeting (everyone welcome)

Location: LeoMar, Boldrini/Bigagli

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

Location: LeoMar, Husar/Vidic

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

Location: LeoMar, Schultz/Bernonville

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

Location: LeoMar, Decker/Hoijarvi

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

Tue 16.00-18.00: Scope and Type of Data to be Served

Location: LeoMar, Vik/Fialkowski


  • 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.

SoltaIntro 1.jpeg | SoltaIntro 2.jpeg

      • 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

Location: LeoMar, Domenico/Gaussev

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

Location: LeoMar, Bigagli/Eckhardt

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 18.00-19.00: General Discussion, with wine and cheese

Group dinner

Thu 8.00-10.00: Networking impediments and opportunities

Location: LeoMar, Kjeld/Ludewig

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: ADN user relations/help, whom, what?

Location: LeoMar, Galmarini/Dye
  • 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?

Location: LeoMar, 'Schultz/Husar

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.

Thu 18.00-19.00: General Discussion, with wine and cheese

Friday: Boat trip
