2 Air quality community spans efforts Monitor the atmosphere (surface, satellite and aerial systems), Model future atmospheric behavior and air quality conditions, Measure and estimate emissions of pollution and pollution forming gases and particles, Combine those information with socio-economic data for decision making analyses.

5 Interoperability Challenges Standalone-project-oriented approaches Multiple interoperability standard implementations Required tailored implementation of standards The user cannot find the data; If he can find it, cannot access it; If he can access it, ; he doesn't know how good they are; if he finds them good, he can not merge them with other data The Users View of IT, NAS 1989

7 Making Project Contributions Reusable Data Do something with the data (add value) Generate Product Deliver Product to Customer Provide Website Access (manual) Provide web service access Provide access to processing/analysis/value- adding services 7

8 Project A Project A combines mul5ple data sources to generate near- real 5me informa5on for the public Project A provides web service interfaces to some of its data and informa5on

9 Project B Project B analyzes surface and satellite data in support of regulatory analysis and provides web services to their analysis output and analysis tools

22 Summary and Issues The air quality interoperability efforts have found some success in using existing web standards to achieve a base level of interoperability Many challenges remain spanning technical issues in making standards work for air quality uses to organization issues in achieving agreement among air quality-specific conventions to standards As the community gains experience in how to implement and tailor the standards they will develop best practices The interoperability efforts described in this abstract have focused on OGC standards. However, there is a desire to evaluate the applicability of other web standards for air quality systems, in particular OPeNDAP.
