Calibration and Validation of NOAA VIIRS Ocean Products for Monitoring Oceans
The on-orbit calibration and validation of satellite ocean products was established for the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA Suomi National Polar–Orbiting Preparatory Project (SNPP) satellite. This effort supported the improvement of ocean color products (water leaving radiance, chlorophyll, and bio-optical properties) that enhance the monitoring of coastal and open waters. As members of the NOAA Joint Polar Satellite System (JPSS) calibration and validation (calval) team, this project team coordinated the calibration of ocean satellite products and tracking the stability of the VIIRS sensor and satellite products. They investigated the sensor characterization and processing software used to derive ocean products and to evaluate the long-term trends of the sensor calibration for processing software. They collected measurements for several cruises; maintained a data stream on the wave-current information system (WavCIS) for NOAA, NASA, and others; and provided calibration data sets for validation of ocean color products for the NOAA VIIRS sensor. The WavCis platform was updated to sensor SN638 and matchup of VIIRS inherent optical properties with cruise flowthrough data for the Bonnie Carrier cruise (Feb 2016) and other cruises that year and in 2017. The calval team participated in the Okeanos Explorer 2018 cruise and collected in situ data for VIIRS calibration and validation followed by data analysis with NOAA team cruise members.
