- 5. Summary • AQ DataNetwork (ADN) demonstrates the application of GEO principles and GEOSS infrastructure • ADN is still too fragile and incomplete for ‘real’ applications • The road toward integrated data systems will be long, bumpy and littered with wrecks of well-intended attempts • The main impediments appear to be human factors; the solutions will have to deal with turf, trust, jealousy…

- 10. GEO AQ CoPis a self- organized group working together to foster application of Earth observations to Air Quality, connecting GEO to the broader user communities and leveraging synergies of collaboration. Rather than competing, it connects and supports the activities of other data integration and dissemination initiatives. Community activities include teleconferences; collaborative website; virtual workshops; gathering user requirements; recording best practices; participation in GEOSS Architecture Implementation Pilots and supporting several GEO Tasks. The main tangible output facilitated by the AQ CoP is the emerging network of interoperable air quality/atmospheric composition data servers (currently 7) that use international OGC WCS/WMS standard data access protocols. The main role of the CoP is to connect and enable this network, as a System of Systems for Air Quality guided by: What few things must be the same so that everything else can be different? The content of the network's data and metadata is accessible through a distributed catalog of shared data resources. The core network content includes datasets from surface-based monitoring networks (7), satellite sensors (5), as well as global/regional models (3), including the MACC global aerosol model.
Editor's Notes
- #3 The vision is to have these data available through an interoperability framework that allows them to be used via various subsets and combinations to support specific research and decision applications There are numerous Earth Observations that are available and in principle useful for air quality applications such as informing the public and enforcing AQ standards. However, connecting a user to the right observations or models is accompanied by an array of hurdles. The GEOSS Common Infrastructure allows the reuse of observations and models for multiple purposes Even in the narrow application of Wildfire smoke, observations and models can be reused.
- #6 There are numerous Earth Observations that are available and in principle useful for air quality applications such as informing the public and enforcing AQ standards. However, there are a multitude of interoperability hurdles hurdles facing this community (can be extended to broader Earth science community) that users face – finding, accessing, quality and data fusion issues. It is redundant for each project to figure out the same things. Coordinating acr Therefore the AQ community has come together to work toward a single interoperability framework that allows them to be used via various subsets and combinations to support specific research and decision applications
- #7 At the end of August 2011, the GEO Air Quality Community of Practice organized a small topical workshop on the Networking of Air Quality Observations and Models where data system practitioners from Europe and North America will discuss interoperability challenges, and share best practices. The central theme of the workshop will be on the implementation of the network, that is turning the current fragile and virtual network into a real network that benefits many organizations. Accordingly, the bulk of the time during the three-day workshop was devoted to the technical issues on the realization of AQ Network. The 30 or so workshop participants represent major data hubs, science teams, AQ decision support systems and other integrating initiatives with common interest in the realization of AQ data networking. The workshop venue is Stomorska, adjacent to Split, Croaotia. The workshop was able to attract the participation of the managers and programmers of the major air quality data hubs in Europe and US, as well as experts on interoperability and networking. Thus the group was quite competent the handle the AQ data networking topic. The meeting allowed the participants to learn about each other's data systems and general perspectives. This was a necessary step toward a shared understanding and for building trust for future inter-dependent data networking. During the open discussion-oriented sessions, the participants were willing and able to articulate the key impediments to networked AQ data systems at their respective organizations. With this, remedies can be pursued. At the end of the meeting the managers and programmers of the major data hubs made a remarkable set of commitments toward making the AQ Data Network happen
