Project “Phases” Technology Development –DataFed development –Architecture development –Use of web technologies to build online tools for air quality data analysis and decision making Technology Application –DataFed Workshops –Technology Infusion –Community building within broader context of interoperability and GEOSS

4. Federation of Earth Science Information Partners (ESIP) REASoN program included requirement for at least 0.25 FTE participate in activities like ESIP and the NASA Earth Science Data Systems Work Group (ESDSWG) An air quality focus group met during the 2005 ESIP Winter Meeting to discuss how ESIP might play a role in advancing the use of earth science data in air quality management. Interest is high within ESIP and air quality is recommended as a new ESIP Air Quality “Cluster” datatools,methods,services brings together groups and helps build links among them in order to achieve an effective use of data in decision-making that could not be achieved by any organization acting on its own. datatools,methods,services a) b) c)...... aids in reuse of data, processing tools and other services so that projects, programs and agencies avoid the end-to-end burden of developing those capabilities or having to create the connections themselves. users

11. DataSpaces DataSpaces further extend the structured metadata by enabling the stakeholder communinty to: –Contribute additional, flexible metadata –Discuss dataset –Collect distributed, dataset-related resources –Connect the structured metadata to community content DataSpaces are workspaces designed to capture the critical community knowledge about the dataset.

14. How you can contribute and benefit Community Building Share your interests and project contributions (like this meeting) Use ESIP for advancing your project objectives (e.g., ‘built-in’ testers, workshops, users…) Make community relevant to your objectives, bring others (data providers, analysts, modelers, decision makers, etc.) into the community Help define the GEOSS Community of Practice Enhance the Information Infrastructure Become a ‘node’ on the air quality interoperability network Learn best practices in implementing standards for sharing your project data and tools Participate in (and influence) the GEOSS Architecture Implementation Pilot Use the AQ Community Information Architecture (register your services in GEOSS, find information resources useful for your project) Participate in the development of air quality information networks Collaborate on AQ Science and Research Projects Define projects that cut across multiple organizations focused on advancing our understanding of particular aspects of AQ science
