Infrared Sounder on Suomi NPP Starts its Mission. Therefore the Data is flowing in from the Cross-track Infrared Sounder (CrIS) instrument aboard NASA’s newest Earth-observing satellite, the Suomi National Polar-orbiting Partnership (NPP).

Suomi was originally intended as a pathfinder for the NPOESS program. Therefore was to have replaced NOAA’s Polar Operational Environmental Satellites and the U.S. Air Force’s Defense Meteorological Satellite Program. Also the Suomi was launched in 2011 after the cancellation of NPOESS. And to serve as a stop-gap between the POES satellites and the Joint Polar Satellite System. It will replace them. Its instruments provide climate measurements that continue prior observations by NASA’s Earth Observing System.
