Husar rhusar@me.wustl.edu The data life cycle consists of the acquisition and the usage parts Usage ActivitiesData Acquisition Data Acquisition and Usage Activities The collected and cleaned data are stored in the repository Data Repository The acquisition part processes the sensory data by firmly linked procedures The usage cycle transforms data into knowledge for decision making The usage activities are more iterative, dynamic procedures Decisions The Federation focuses on data usage activities and presumes repositories

Husar rhusar@me.wustl.edu The challenge is to design a general supportive infrastructure Simply connecting the relevant provides for each info product is repetitive, rigid and messy Wrappers Where? What? When? Federate Data Structuring Structuring the heterogeneous data into where-when-what ‘cubes’ simplifies the mess Slice & Dice Explore Data Viewers The ‘cubed’ data can be accessed and explored by slicing-dicing tools Programs Integrate Understand More elaborate data integration and fusion can be done by web service chaining Integrated Data Infrastructure for Air Quality - IDAQ ESIP AQ Cluster 050510 Draft rhusar@me.wustl.edu Providers supply the ‘raw material’ (data and models) for ‘refined’ info products Emission Surface Satellite Model Single Datasets Providers The info system infrastructure needs to facilitate the creation of info products AQ Compliance Nowcast/Forecast Status & Trends Find Data Gaps ID New Problems ……… Info Products Reports Networking Reuse This infrastructure support for IDAQ can be provided by the ESIP Federation
