Paper Abstract

Sea surface reflection, such as sunglint and white cap, causes significant error in the ocean color estimation. Current algorithms include statistical correction using lower-resolution wind speed data. However, we cannot use the scheme in the coastal area due to variable winds and air-sea stability caused by the coastal geographical structure. Linear combination technique which was proposed by Frouin et al. can estimate chlorophyll-a concentration even in high sunglint and whitecap areas. That indicates sunglint error of ocean-color imagery can/should be corrected using multispectral channels not using ancillary wind fields. We tried to correct sunglint using near infrared and shortwave infrared (2.1µm) channels. The correction improved estimation of water leaving reflectance and chlorophyll-a concentration, however, we still need additional information to estimate proper aerosol and sunglint simultaneously.
