Abstract

The atmospheric correction for the ocean color remote sensing is an important and essential process, more than 90% of signals received by sensors are caused by scattering of atmosphere. The assumption of negligible water-leaving radiance at near-infrared (NIR) bands in the embedded standard atmospheric correction method is not valid for Case II waters, and its main errors are occurred by the estimation errors of the aerosol property and quantity which are highly variable in both space and time. In this study, our main purpose is to develop the advanced atmospheric correction method by using FTIR spectrometer. The aerosol information derived from FTIR spectrometer on the same day in Case II waters and then modify the standard atmospheric correction algorithm to retrieve the water-leaving reflectance. Results of comparisons with standard atmospheric Correction, the modified atmospheric correction is available to estimate the aerosol properties and effective to atmospheric correction in Case II waters.
