Retrieval Algorithm for NPOESS-CRIMSS and Future Operational Sounders

The Cross-Track Infrared and Microwave Sounder Suite (CrIMSS) consists of a microwave radiometer and an infrared interferometer and is scheduled to fly on the NPP and NPOESS satellites. The sensors are designed for the accurate measurement of atmospheric pressure, temperature and moisture profiles. The core algorithm upon which the CrIMSS retrievals are based was initially developed and tested with data from the DMSP Block 5D3 sensor suite. In addition to NPOESS, the algorithm is equally applicable to other sensor suites such as EOS and GOES. This paper presents an overview of the CrIMSS sensors and the retrieval algorithm. Validation of the algorithm with current satellite sounder data will also be presented.
