The Cross-track Infrared and Microwave Sounder Suite (CrIMSS) will be flying on the National Polar Orbiting Environmental Satellite System (NPOESS) and NASA's NPOESS Preparatory Project (NPP) satellites. Atmospheric vertical temperature and moisture profiles are the two key Environmental Data Records (EDRs) to be measured by the CrIMSS. The retrieval algorithm that was developed to produce these two EDRs has been delivered to Northrop Grumman Space Technology (NGST) and gone through NGST's rigorous pre-launch algorithm performance verification process. In this paper, we will present the methodology and test data used in our verification process. The current estimate of the CrIMSS EDR algorithm’s performance will also be presented.
