The Joint Polar Satellite System (JPSS) is a U.S. National Oceanic and Atmospheric Administration (NOAA) operational satellite program in collaboration with joint international partnerships as well as the U.S. National Aeronautical Space Administration (NASA). The NPP satellite, a JPSS risk-reduction and data continuity operational mission, is scheduled for an October 2011 launch. The primary mission of the JPSS program is to provide sensor and environmental data records (SDRs and EDRs) to NOAA's operational users. NPP/JPSS will include the Cross-track Infrared Microwave Sounding Suite (CrIMSS), a synergistic sounding system consisting of the infrared Cross-track Infrared Sounder (CrIS) and the microwave Advanced Technology Microwave Sounder (ATMS). CrIMSS will provide SDRs (calibrated radiance spectra) leading to the generation of three EDRs, namely the atmospheric vertical temperature, moisture and pressure profiles (AVTP, AVMP and AVPP, respectively), with the AVTP and the AVMP being JPSS Key Performance Parameters (KPPs). To ensure these data products comply with the requirements of the sponsoring agencies, a calibration/validation (cal/val) plan was devised involving science and user community leadership and participation, and demonstrated, cost-effective approaches. With pre-launch cal/val activities currently underway, this presentation will highlight the current status and schedule for the near- and far-term validation of the NPP and JPSS CrIMSS EDRs.
