The Climate Data Portal links geographically distributed climate data servers in Seattle, WA, Silver Spring Md, and Honolulu, HI into a network to provide a portal to distributed data in a common data format to researchers and modeling centers. Applications for the Climate Data Portal include interactive, 4-D data selection utilities, desktop Java graphics, and data delivery from various NOAA ENSO observing systems and NOAA NODC historical data archives to modeling centers and to the scientist's desktop in a common, consistent data stream. Data from distributed data servers can be plotted together on the users desktop with a Java desktop application (ftp://www.epic.noaa.gov/java/CDPclient/install.html) or through web pages (http://www.epic.noaa.gov/cdp/).
