Paper Abstract

As an integral part of the VIIRS sensor calibration and validation efforts, our group has been continuously monitoring the validity of the Visible Infrared Imager Radiometer Suite (VIIRS)’s Ocean Color (OC) and atmospheric data stream through time series in-situ data acquired at the observatory sites which are part of the AERONET – OC network. This paper addresses the preliminary evaluations of the VIIRS sensor’s performance for retrieving OC data of typical coastal water environments, by carrying out time-series, as well as qualitative and quantitative match-up comparisons analysis between in-situ and satellite retrieved OC data. Initial time-series match-up comparisons carried out for almost a year period (January to December, 2012) show that VIIRS data exhibits strong temporal and statistical agreements with AERONET-OC data demonstrating a potential for enhanced coastal water monitoring from space. VIIRS data processing schemes which apply different vicarious calibration gains are compared and analyzed based on AERONET-OC data as well as OC retrievals of the Moderate Resolution Imaging Spectro-radiometer (MODIS) sensor aboard the Aqua satellite. The underlying cause of the discrepancies observed in VIIRS retrieved normalized water-leaving radiances is also investigated.
