As part of the Joint Polar Satellite System JPSS Ocean CalVal Team, Naval Research Lab - Stennis Space Center NRL-SSC has been working lo facilitate calibration and validation of the Visible Infrared Imaging Radiometer Suite VIIRS ocean color products By relaxing the constraints of the NASA Ocean Biology Processing Group OBPG methodology for vicarious calibration of ocean color satellites and utilizing the Aerosol Robotic Network Ocean Color AERONET-OC system to provide in situ data, we investigated differences between remotely sensed water leaving radiance and the expected m situ response in coastal areas and compare the results to traditional Marine Optical Buoy MOBY calibrationvalidation activities. An evaluation of the Suomi National Polar-Orbiting Partnership SNPP-VIIRS ocean color products was performed in coastal waters using the time series data obtained from the Northern Gulf of Mexico AERONET-OC site, WaveCIS. The coastal site provides different water types with varying complexity of CDOM, sedimentary, and chlorophyll components Time series data .sets were used to develop a vicarious gain adjustment VGA at this site, which provides a regional top of the atmospheric TOA spectral offset to compare the standard MOBY spectral calibration gain in open ocean waters.
