Joint Polar Satellite System (JPSS) Calibration and Validation

Abstract

The successful launch of the Joint Polar Satellite System (JPSS) satellite -1 (JPSS-1, now named as NOAA-20) is providing an array of atmospheric, land, and ocean data products from four major instruments: 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 (S-NPP) satellite. The JPSS program at the center for Satellite Applications and Research (JSTAR) led the efforts for development of algorithms to generate Sensor Data Records (SDRs) and Environmental Data Records (EDRs), as well as the Calibration and Validation (Cal/Val) of the SDRs and EDRs. By now the Cal/Val of NOAA-20 products have been performed as planned, all the NOAA-20 Key Performance Parameters (KPPs) have reached Validated Maturity and in operation. This paper will present an overview of JPSS Cal Val efforts. We will provide an update of the Cal/Val maturity status for the NOAA-20 data products. In addition, the operational implementation status of JPSS enterprise science algorithms for product generation and science product reprocessing efforts for the S-NPP mission will be discussed.
