  • The current Pilot AQ Network consists of about about half a dozen data hubs offer part of their data holdings through OGC-standard WCS web services. Interoperability is among these servers is assured by a jointly developed, open-source server software that is installed at each data hub. The offered data are published and can be found through the prototype Community catalog and then accessed by OGC-compliant client software, regardless where the data are located. Together, the distributed servers, the data catalog and the clients are the three components of the service-oriented, loosely coupled AQ Network. The AQ data network Pilot resulted from the close collaboration of a few groups and it is still small, fragile and limited in many ways. The server implementation required to make numerous arbitrary decisions. The technical realization of an extended, inclusive and robust network will be the focus of the broader community represented at the workshop. The server-level topics include Selection and use of standards, conventions and community arrangements. Server issues for gridded data for satellite, emissions and model data Server issues for station-point monitoring data Server maintenance and software support Server performance issue and prectices Network level topics include

  • 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

  • At the end of August 2011, the GEO Air Quality Community of Practice is organizing a small topical workshop on the Networking of Air Quality Observations and Models. Data system practitioners from Europe and North America will address interoperability challenges, share best practices and seek ways to expand the network. The central theme of the workshop will be on the implementation of interoperable data server nodes, so the majority of the three-day agenda will be devoted to the technical aspects of server design and the realization of the interoperable AQ Data Network. The majority of the 30 or so workshop participants are data system developers and managers. They represent about 20 organizations including data hubs that provide access to data as well as science teams and decision support systems that are users of observations, emissions and model data. The workshop venue is located in Stomorska, adjacent to Split, Croaotia.

    13. 13. • 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.
    14. 14. • The creation of an information system for Earth Sciences has been a grand challenge for decades• It has been pursued by innumerable workshops, vision statements, pilot projects etc…• There were many tries Progress has been slow …• “The road toward integrated Earth Science info systems is littered with wrecks of well-intended attempts..”•
    15. 15. • We know that info systems like libraries and the internet provide useful services• The info technologies and the engineering design of these systems is understood.• However, the science, the explanations of how these info systems work 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? – Are there suitable ‘laws of nature’, equivalent to conservation of mass and energy?
    16. 16. What will be discussed?The state of ADN including key impediments; co-development of serversoftware and tools; sharing best practices Workshop Focus: Technical Realization of AQ Network.
