Advanced Technology Microwave Sounder - The Advanced Technology Microwave Sounder (ATMS) on board Suomi NPP is a 22 channel microwave sounder that provides atmospheric temperature and moisture data for operational weather and climate applications. The ATMS instrument provides continuous cross-track scanning in an 824 km sun-synchronous orbit at a spatial resolution of 15.8 km to 74.8 km. ATMS data are available from the NOAA Comprehensive Large Array-Data Stewardship System (CLASS) in the Hierarchical Data Format v.5 (HDF5) with metadata attributes included.
(01/31/2022) - Please note, CLASS offers a reprocessed version (pre 10/16/2019) of this data using the improved algorithms. See the RPATMSSDR products search page for details.
(06/01/2018) - Many products from NOAA-20 are now available through CLASS back to Beta Maturity. Please note that the start dates listed below for each datatype apply to SNPP files. The start dates for all products by maturity levels by satellite id are available on NOAA's STAR website at https://www.star.nesdis.noaa.gov/jpss/AlgorithmMaturity.php. Under each date there is a link to the full review of the product along with the latest readme on the last column. We encourage all users to assess product maturity before ordering and applying the data.
Beginning on August 11-14, 2014, CLASS started receiving the majority of JPSS data in gzip compressed format. The file names remained the same. Other than the file size being smaller, users do not need to make any changes to their software to use the data.
