The Joint Polar Satellite System (JPSS) launched the Suomi National Polar-orbiting Partnership (S-NPP) satellite in the year 2011 with 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). The JPSS program at the center for Satellite Applications and Research (JSTAR) led the development of science algorithms to generate Sensor Data Records (SDRs) and Environmental Data Records (EDRs), and performed calibration and validation of these science data products. All of these S-NPP data products have passed through Beta, Provisional, and Validated maturity stages over the time and have now reached the Long Term Monitoring (LTM) phase. These products are operationally available to all of the user agencies worldwide through NOAA Comprehensive Large Array-data Stewardship System (CLASS).
Based on the directions from the NOAA JPSS Office (NJO), the JSTAR science teams have started implementing enterprise algorithms for many of the S-NPP priority 3 and 4 products for both S-NPP and JPSS-1. Examples of enterprise algorithms currently producing S-NPP EDR products are: the VIIRS Enterprise Cloud Mask (ECM), Active Fires (AF), Aerosol Optical Thickness and Detection products (AOT, ADP), the ozone EDR product suite (V8TOz and V8Pro), the NOAA Unique Combined Atmospheric Processing System (NUCAPS) products using hyper-spectral CrIS and ATMS, and the Microwave Integrated Retrieval System (MIRS) products from ATMS. All of these algorithms met the product accuracy and precision requirements for S-NPP and showed improved performance metrics through validation with ground measurements and other correlative data products. These enterprise algorithms are currently in S-NPP Data Exploitation (NDE) operations for S-NPP, and many other enterprise algorithms will be transitioned to NDE operations by the end of 2017.
The JSTAR science teams have realized that consistent long-term product quality metrics can only be achieved through reprocessing with algorithms that has reached validated maturity. Since the EDR products get impacted both by upstream SDR product changes (due to uncovered deficiencies and improved sensor characterizations in SDR algorithms) as well as EDR algorithm changes (through Beta, Provisional, and Validated maturity stages) the science teams realized the need to reprocess both SDR and EDR products in order to maintain high quality and consistency for satellite research and applications. With regards to SDR products, the JSTAR science teams have reprocessed mission-long SDR products from ATMS, CrIS and OMPS. The large data storage requirements precluded reprocessing mission-long VIIRS SDR products, so the science teams have reprocessed just four weeks VIIRS SDR products as test data to evaluate EDR improvements using reprocessed SDR products.
This paper presents the current status of the S-NPP EDR reprocessing plans using enterprise EDR algorithms. Status of EDR enterprise algorithms, plans and schedules of operationalization through NDE are discussed. The availability of matured EDR algorithms for EDR product reprocessing, product dependencies for setting up complete reprocessing chains, and the resources needed by individual EDR teams are presented. Some of the other S-NPP reprocessed EDR products available from other sources are also outlined for user utilization.
