Latest Improvements of ATMS TDR/SDR Sciences and Algorithms for Reprocessing

Since the SNPP launch, ATMS is well calibrated and the sensor data records (SDR) and environmental data records (EDR) are generated through the JPSS ground Interface Data Processing System (IDPS) and operationally disseminated to NWP centers and other stakeholders. However, JPSS IDPS has undergone through many versions for maintenance (Mx) build code since its initial release. In each version, there are some important changes in instrument calibration, retrieval physics and quality flags and as a result, the quality of satellite products is improved. For example, in Mx8.11, the ATMS SDR products will be upgraded from calibration in temperature space to radiance calibration. This work introduces major science improvements on operational ATMS TDR/SDR reprocessing algorithms. Validation results are also presented in this work.
