The Comprehensive Large Array-data Stewardship System (CLASS) is a data repository for environmental data collected by NOAA. Products include data from polar orbiting satellites, meteorological satellites, sea surface temperature (SST) data, sea surface height data, and more. CLASS is a key component of NOAA’s integrated global observation and data management system. CLASS distributs data from the following satellite and observing systems: (1) NOAA Polar-orbiting Operational Environmental Satellite (POES); (2) NOAA’s Geostationary Operational Environmental Satellite (GOES); (3) NASA’s Earth Observing System (EOS); (4) U.S. Department of Defense Meteorological Satellite Program (DMSP). CLASS is evolving to support additional satellite data streams, environmental sensors, and data from buoys, plus geophysical and solar environmental data. CLASS is in its third year of a major 10-year growth program, adding new data sets and functionality to support a broader user base.
