  1. AMS / IIPS, Jan 10-15, 1999, Dallas, TX NOAAServer: Unified accessto distributed NOAA data Ernest Daddio, NOAA/ESDIM Steve Hankin, NOAA/PMEL Donald Denbo, NOAA/PMEL/JISAO Nancy Soreide, NOAA/PMEL Saul Rosenberg, NOAA/ESDIM Joe Sirott, NOAA/PMEL/JISAO Steve Roberts, UCAR/JOSS W.

  2. NOAAServer • Objective: Provide centralized, unified access to distributed NOAA data • Participants: All of the NOAA Line Offices • National Environmental Satellite Data and Information Service • National Marine Fisheries Service • National Ocean Service • National Weather Service • Oceanic and Atmospheric Research

  3. NOAAServer • Initiated in NOAA’s Environmental Services Data and Information Management (ESDIM) office in 1995 • Integrates 14 distributed data servers • Over 15,000 metadata descriptions • Available from the NOAA Home Page • http://www.noaa.gov • http://www.esdim.noaa.gov/NOAAServer

  4. Operational NOAAServer • Locating data: • Enter search criteria • The NOAAServer returns a list of data collections meeting the search criteria • View a description of the data collection • If data is on-line, interact to subset data, obtain plot or listing of data • If sub-setted data is sufficiently small, data can be downloaded to the users disk

  5. Operational NOAAServer* • Representative data: • satellite images • time series of oceanographic and meteorological station measurements • two-dimensional oceanic parameters • text documents • vertical profiles of measurements through the atmosphere and the ocean *http://www.esdim.noaa.gov/NOAAServer

  8. Operational NOAAServer • Integrates NOAA Data and Information Services on the Web • Centralized search for NOAA wide data holdings: • Search, view, download/order distributed NOAA data • http and conventional, legacy CGI scripts • but different datasets have different navigation and interface characteristics

  9. Where are we headed? • Recent developments include methods for providing a centralized and unified data access • Next Generation NOAAServer • Data is easily located and accessed • User sees a consistent search and navigation interface • So data is viewed consistently across servers • Better service to a wider audience

  10. Next Generation NOAAServerPrototype demonstration • connects 6 geographically distributed data servers in Silver Spring, Boulder, Seattle • CORBA for network connections • unified interactive Java graphics* • data from distributed servers are co-plotted together on the same axis on the users desktop * http://www.epic.noaa.gov/NOAAServer/sgt

  11. Next Generation NOAAServer Gridded COADS Climatology dataset (red) plotted with buoy time series from TAO (green)

  12. Next Generation NOAAServer COADS data (Seattle) and buoy time series from NODC (Silver Spring) & PMEL/TAO (Seattle)

  13. Next Generation NOAAServer Atmospheric profile data (UCAR,Boulder) plotted with ocean profiles (PMEL,Seattle)

  14. Next Generation NOAAServer Architecture • Client (user’s web browser) • Javascript and Java Applets • Mirror Site Web Server • Application logic • Graphics • Local Data Server • Present data as Objects to network • Existing Legacy System • SQL capable databases • netCDF, custom applications
