A Look on the S-NPP CrIS Life Cycle Data Reprocessing

Since the launch of the Suomi National Polar-orbiting Partnership (S-NPP) satellite in 2011, a lot of efforts have been put onto the Cross-Track Infrared Sounder (CrIS) to make sure that users receive CrIS science data record (SDR) with the highest quality. Needless to say, during the past five years, lots of corrections and updates in both software and science have been carefully developed and implemented. Particularly for CrIS, an important change, transition from truncated resolution to full resolution, has been made since December, 2014. Such accumulated effort is extremely valuable to the satellite date users. Year 2016 is not only the fifth year, the last year of the instrument design life of the S-NPP project, but also the year before the launch of its successor, Joint Polar Satellite System-1. Hence it is the vital and right moment for us to collect and integrate all the knowledge that accumulated over the past 5 years to reprocess the S-NPP instruments life cycle data. Doing so will not only provide unified SDR of each S-NPP instrument to its state-of-the-art calibration knowledge, but will also establish a mean state of data that can be highly efficient and valuable to the Numerical Weather Prediction (NWP) community for weather and climate applications. This research focuses on exhibiting current progress on the status of the S-NPP CrIS life cycle data reprocessing. Life cycle time series and comparisons with old processing records and model simulation results of important parameters, such as brightness temperatures, gain, noise sensitivity and etc will be included here.
