The Joint Polar Satellite System (JPSS) is the Nation's new generation polar-orbiting operational environmental satellite system. JPSS-1, or NOAA-20 as it will be known once operational, will host an array of instruments including the Visible Infrared Imaging Radiometer Suite (VIIRS), the Cross-track Infrared Sounder (CrIS), the Advanced Technology Microwave Sounder (ATMS), and the Ozone Mapping and Profiler Suite (OMPS). These instruments are similar to the instruments currently operating on the Suomi National Polar-orbiting Partnership (SNPP) satellite, a predecessor designed to bridge for the JPSS constellation. The JPSS-1 satellite will produce baseline and new products as a direct result of the instrument upgrades (e.g. CrIS & OMPS) and science improvements. JPSS-STAR (JSTAR) teams led efforts to develop and deliver the updated the sensor data records (SDRs) and environment data records (EDRs) algorithms for JPSS-1 to meet the program requirements. Algorithms to process JPSS-1 instrument data into sensor and environmental data products have been developed based on the experiences gained through the S-NPP algorithms, with consideration of mitigating JPSS-1 instrument waivers based on pre-launch instrument testing data. Optimizations are also being performed on JPSS-1 upgrades, which account for science improvements to produce additional or improved data products. The updated algorithms including look up tables/coefficient files have been developed and tested by science teams using the JPSS-1 instrument testing data and S-NPP proxy data. This paper presents an overview of the major JPSS-1 science algorithm updates, such as ATMS full radiance calibration, CrIS full resolution, VIIRS GEO code change, and OMPS SDR updates. The latest status of NOAA enterprise algorithms developments will be briefed. Major progresses on reprocessing the Suomi-NPP mission life-cycle data records will also be highlighted.
