Visible Infrared Imaging Radiometer Suite (VIIRS) Data Records from Suomi NPP - The Visible Infrared Imaging Radiometer Suite (VIIRS) is a scanning radiometer that collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. The VIIRS instrument includes 22 spectral bands: 16 moderate-resolution, narrow-spectral-band at 750 meter resolution, five imaging-resolution, narrow-spectral-band at 375 meter resolution and one Day-Night Band imaging broadband at 750 meter resolution. VIIRS data are distributed through the NOAA Comprehensive Large Array-Data Stewardship System (CLASS) in the Hierarchical Data Format v.5 (HDF5) with metadata attributes included.
(Posted 09/13/2023) - Please note, CLASS offers a reprocessed version (pre 05/01/2020) of this data using the improved algorithms. See the RPVIIRSSDR products search page for details.
(Posted 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.
