1. HTAP Data Network GEO Task DA-09-02d: Atm. Model Evaluation Network Project Officer: Terry Keating, EPA ESIP Meeting, Air Quality Workgroup January 5, 2011, Washington DC, US FZ Jülich – Model Server DataFed – AQ Data Server & Client NEISGEI Emission Server NILU – EBAS Data Server Other Nodes: AQS, RSIG, VIEWS Giovanni HTAP - Analysis

2. HTAP Data Network GEO Task DA-09-02d: Atm. Model Evaluation Network Demonstration of a service-oriented, loosely coupled air quality data sharing network. Implemented using standards and conventions for publishing, finding and accessing distributed holdings of atmospheric model outputs and observations. The main output is a portable open-source WCS data server software and tools. The HTAP Pilot is a contributions to GEOSS through GEO Task DA-09-02d: Atmospheric Model Evaluation Network.

3. Interoperability Stack What few things must be the same so that everything else can be different?

6. Additional Services for: Catalog, Data Browsing, Processing

7. Server Software: Community Developed, Open Source on SourceForge

8. Project Status on the Collaboration Continuum: Between Cooperation and Collaboration

17. GEO AQ CoP Poster What is the GEO AQ CoP? – Self- organized group working together to foster application of Eos to AQ – Rather than competing, it connects and supports the activities of other data integration communities and initiatives CoP Activities for GEOSS – AIP 3, AQ Community Catalog – WCS Server Software, Co- developed, Shared CoP Activities for Users – Catalog and help access to AQ- relevant data and tools – Foster collaborative projects and global-regional integration
