Day 1: State of AQ InteroperabilityDay 2: Technical Discussion Day 3: Consensus? What Next? Points of Contact: Rudolf Husar (rhusar@wustl.edu), Martin Schultz (m.schultz@fz-juelich.de) Šolta, Croatia, August 24-26, 2011

2. Workshop Goals (Bravo Martin!) • Get to know each other • Identify core AQ applications and sharable data sets • Exchange state-of-the-art, interoperability practices • Address technical and programmatic issues • Have fun

3. Preliminary Agenda • Wednesday, 25 Aug: State of AQ Interoperability • Participant presentations • Integrating Initiatives, Agencies, ‘End Users’, their needs, roles • GEO AQ CoP role, relationships, contributions • Thursday, 26 Aug: Technical Realization of Interoperability • Syntactic issues (Improved standards? WCS, WMS, CSW…; netcdf, other formats) • Semantic issues (Metadata for finding and understanding data? CF? ) • Programmatic issues (Which data can be shared by whom? Data versions, etc.?) • Friday, 27 Aug: Outcomes. Consensus? Next? • What few things must be the SAME, so that everything else can be DIFFERENT? • How can we collaborate? Interact with other Initiatives, Agencies, Users? • Do we have common long-term goals? Next steps?

4. Air Quality Data Network • Uses OGC standards (.. netCDF), CF Conventions, ISO metadata • Share software code, best practices • Seven servers, three clients (HTAP, MACC, ACP, EE, EMEP, VIEWS, PHAROS, CIERA,RSIG,..) • AQ Community Catalog for finding • Test app. for EPA Except. Events AQ Data Network is still fragile, incomplete and inadequate for real apps, but demonstrates fine grained data networking with GEOSS infrastructure and process AQ Data Find & Access AQ Data Network: Servers

12. The GEO AQ CoP is a self-organized voluntary group that fosters the use of Earth observations to air quality management and science by leveraging synergies of sharing and collaboration. • Community activities include collaborative website; workshops; gathering user requirements; sharing tools and best practices as well as aiding other communities: data portals, science teams and decision support activities. • A persistent output facilitated by the AQ CoP is a network of air quality/atmospheric composition data servers that use OGC-standard protocols and the GEOSS interoperability process. • Searching, browsing and accessing data from monitoring networks, satellite sensors, emissions, as well as from AQ models is through a Community Catalog.

13. We know that information systems like libraries and the internet provide useful services • The technologies and the engineering of these systems is understood but the science is not in hand… • What causes information to be generated, transmitted and ‘consumed’? • What are the driving forces to the flow of information? Provider push, consumer pull? Impediments.. …Can you push a rope? • What are there suitable ‘laws of nature’, equivalent to conservation of mass and energy? • Earth Science info systems are still in the pre-scientific era • Hence, first need to observe these info systems ..

14. The of GEOSS (and most other EO integrating initiatives) is create more societal benefit from Earth Observations and Models Effective creation of societal benefit hinges on seamless data flow and re-use, so a universal value is the ability the share and re-use data. Hence AQ CoP chose to focus on facilitating Air Quality Data Network.

15. We also understand that the creation of an Earth Science information system has been a grand challenge for decades…. • …and that the “The road toward integrated Earth Science info systems is littered with wrecks of well-intended attempts..” • So, challenge is how to make more progress this time..
