NSF Unidata's THREDDS Data Server

We make a variety of data available from our remote access server thredds.ucar.edu. Note that the NSF Unidata Program Center is not an operational data center—we operate servers as demonstrations of the technology we develop, and we hope to help community members gain the expertise to operate similar servers at their own institutions (note that we also provide equipment grants through the Community Equipment Awards program to help community members implement these technologies.) Still, we strive to keep our demonstration servers running smoothly, and we have an excellent “uptime” record.

This page provides information on the data available from our THREDDS Data Server.
