## 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

## 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.noaa.gov/)_
- _[http://www.esdim.noaa.gov/NOAAServer](http://www.esdim.noaa.gov/NOAAServer)_

## 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

## 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

## 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

## 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

## Next Generation NOAAServerPrototype 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
