The National Geophysical Data Center (NGDC)
The National Geophysical Data Center (NGDC) is the national repository for geophysical data, one of three National Oceanic and Atmospheric (NOAA) National Data Centers, and part of the US Department of Commerce (USDOC) and the National Environmental Satellite, Data, and Information Service (NESDIS). NGDC manages environmental data in the disciplines of marine geology and geophysics, paleoclimatology, solar-terrestrial physics, solid earth geophysics, and glaciology (snow and ice). In each of these fields NGDC also operates a World Data Center (WDC-A) discipline center serving to oversee the acquisition and exchange of global data. NGDC's data holdings currently contain more than 300 digital and analog databases. Data and inventories in many disciplines are fully searchable and selected listings, data, and images can be downloaded directly or via an FTP or Gopher archive. (A link is also provided to NOAA's NOAAServer, which offers cross-disciplinary searches of data available from NOAA Data Centers and Centers of Data, including NGDC.) Specific NGDC data categories include Solar-Terrestrial Physics (STP), Solar and Upper Atmosphere, Ionosphere, Geomag (ground-based measurements of the geomagnetosphere), GOES SEM (energetic particle, x-ray, and magnetic field measurements at geosynchronous altitude), GOES SXI (Solar X-Ray Imager), NOAA/POES (energetic particle measurements at polar-orbit altitude), and DMSP (cloud imagery, city lights, fires, energetic particles).
