The NPOESS Preparatory Project (NPP) is on track to launch October 2011. The sounding Environment Data Records (EDRs) generated from NPP include the Atmospheric Vertical Temperature Profile (AVTP), Atmospheric Vertical Moisture Profile (AVMP), and the Atmospheric Vertical Pressure Profile (AVPP). The AVTP and the AVMP are both Key Performance Parameters (KPPs) and being used for initialization of high-resolution NWP models, atmospheric stability, etc.. This paper summarizes the sounding EDRs pre-launch performance characterization and provides an update of the NPP CrIMSS Cal Val activities. A first look of the CrIMSS products based on real NPP observation will also be presented.
