Abstract
The atmospheric correction for the ocean color remote sensing is the most important technique to retrieve the waterleaving radiance, which is less than about 10% of the satellite radiance. In Case II waters, the standard atmospheric correction method embedded in SeaDAS frequently yields negative waterleaving radiance, and its major uncertainties are occurred by the estimation error of atmospheric aerosols that is highly variable in both space and time. In this paper, a modified atmospheric correction method was proposed to correct the atmospheric aerosol effect in Case II waters. The aerosol information derived from multi-angles data in Case II waters and then modify the standard atmospheric correction algorithm to retrieve the waterleaving radiance. From the comparison of the standard atmospheric correction algorithm and the modified atmospheric correction algorithm, the results showed that the modified atmospheric correction method could be effective in Case II waters.
