NUCAPS Outgoing Longwave Radiation Products

Since May 21, 2021, the S-NPP CrIS Sensor Data Records (SDR) processing has failed.
All CrIS-SCIENCE-SDR products for S-NPP will be unavailable indefinitely.
The CrIS instrument on the NOAA-20 spacecraft continues to provide CrIS data needs as the primary satellite.


  • All the trace gases products derived from the Infrared Atmospheric Sounding Interferometer (IASI) and the NOAA Unique Combined Atmospheric Processing System (NUCAPS) are not validated yet by the science community and users should use them with precaution and at their own risks. These products will be updated soon after a through science validation.
