The Comprehensive Large Array-data Stewardship System (CLASS) is an electronic library of NOAA environmental data. This web site provides capabilities for finding and obtaining those data.

CLASS is NOAA's premier on-line facility for the distribution of NOAA and US Department of Defense (DoD) Polar-orbiting Operational Environmental Satellite (POES) data, NOAA's Geostationary Operational Environmental Satellite (GOES) data, and derived data.

NOTICE:

  • Public Release of the Jason-2 Geophysical Data Records: The Jason-2 Geophysical Data Records (GDRs) are now publicly available from CLASS. These GDRs have been extensively validated by the Ocean Surface Topography Science Team and demonstrate excellent data quality and consistency with the Jason-1 GDRs. The data are available since Jason-2's launch on 20 June 2008. Further details about the data and its known limitations are available here.
