As part of the the Joint Polar Satellite System (JPSS) satellite-1 (JPSS-1, referred hereafter as NOAA-20) post-launch operations, the JPSS program at the Center for Satellite Applications and Research (JSTAR) has laid out the plans for calibration and validation (Cal/Val) of JPSS-1 sensor and environmental data records (SDRs, EDRs). The SDRs, imagery EDRs, and some of the other EDR products prioritized as Key Performance Parameters are in operations and are going through Beta, Provisional, and Validated maturity reviews. The JSTAR teams have also initiated the operational implementation and execution of cal/val plans and schedules for a vast number of EDR products for atmosphere, land, ocean, and cryosphere applications. Quality monitoring tools such as the Integrated Calibration and Validation System and the EDR Long Term Monitoring have been augmented for JPSS-1 to provide improved science trending and analysis for anomaly resolution. With the availability of six years of high quality data from products from the Suomi National Polar-orbiting Partnership (S- NPP) satellite (launched in October 2011), and the continuity of products from the JPSS-1 satellite, the JSTAR science teams are now preparing towards the generation of consistent long-term science data products using enterprise algorithms and reprocessing efforts. This paper presents an insight into these processes with examples of science data products operationally available from the S- NPP satellite and the first light products from JPSS-1 suite of instruments.
