We will start out by highlighting significant trends in air pollution monitoring and management Next we will describe an agile information system architecture for air quality decision support Finally, we will show the application of this architecture and technologies for two use cases: a real time smoke event analysis and a long-term model evaluation
The HTAP Data Network Pilot is a demonstration of a service-oriented, loosely coupled air quality data sharing network. It is implemented using international standards and conventions for publishing, finding and accessing distributed holdings of atmospheric model outputs and observations. The portable WCS data server software and the tools developed and used in this HTAP Pilot are contributions to GEOSS through GEO Task DA-09-02d: Atmospheric Model Evaluation Network.
First a recap of tree basic ideas for GEOSS. Any single problem requires many datasets Any dataset will serve many communities The PULL by data users and the PUSH by data providers are driving forces for the flow of data
However, there are also strong impediments to the flow of data, both technological and social. A guiding principle for interoperability is “What few things must be the same so that everything else be different?” Whats the minimum set of protocols should we agree on so that we have an “Internet” for data?
