  1. GEO Air Quality Community Catalog ABSTRACT The Air Quality Data Network (ADN) facilitates finding, accessing and merging air quality-related observations, emissions and models. The approach of ADN is to connect and enable existing globally distributed AQ Data Portals by a standards-based data-sharing infrastructure, using GEOSS data sharing principles. ADN is guided by the GEO AQ Community of Practice, a self-organized voluntary group that fosters the application of Earth observations to air quality management and science. Two key facilities of the Network are the AQ Community Catalog (AQ ComCat, http://webapps.datafed.net/CORE.uFIND) and a set of Application Programs. In the Network, data resources are 'published' by completing a registration form based on ISO 19115 standard as extended to include AQ domain-specific metadata. AQ ComCat makes the metadata accessible as a service to Catalogs or Brokers components such as GICat. Users can access all the data though a data browser interface and faceted search facility. The service-oriented application development framework (DataFed client) makes it easy to create and configure such ‘cloud’-based applications. Both the AQ Community Catalog, and a set of Network-based tools will be demonstrated, including applications for: Model Evaluation; Emission-Observation Comparisons; Spatial-Temporal Pollutant Characterization and Real-Time monitoring Consoles.
