Data Description

    JPSS VIIRS Imagery Band EDR (VIIRSI_EDR)
    This data family contains the raw, sensor and environmental data records from the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (S-NPP) satellite. VIIRS is a scanning radiometer that collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth's albedo. VIIRS extends and improves upon a series of measurements initiated by the NOAA Advanced Very High Resolution Radiometer (AVHRR) and the NASA Moderate Resolution Imaging Spectroradiometer (MODIS).

Notes

(Posted 11/13/2025) - On November 11th 2025 at 11:29 UTC, the S-NPP VIIRS instrument experienced an anomaly with the rotating telescope assembly. Engineers were able to restore the instrument to an operational state by November 12th 2025 16:29:18 UTC. All data from this time frame is unrecoverable.

(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.
