NOAA ATOVS Sounding Products

NOAA ATOVS Sounding Products are open Level 2 atmospheric sounding products distributed through NOAA CLASS for the TOVS and ATOVS product family.^[1][2] The archive covers temperature and humidity profiles and related atmospheric products from polar-orbiting satellites.^[1] ATOVS is a heritage multi-instrument sounding package; current operational workflows have shifted toward newer sounders and retrieval systems, so buyer evaluation should treat it as archive and continuity data rather than a current-generation feed.^[1][2] Access is open public archive access through NOAA CLASS, with free public distribution for the listed product family.^[1] The product family is relevant for global atmospheric sounding, historical retrieval work, and workflows that need temperature and humidity profile records from NOAA's polar-orbiting sounder archive.^[1][2] It is not an imagery product; its use cases center on profile retrieval and polar-orbiting sounder archive access.^[1]
