The optical thickness and Angstrom coefficient of the aerosols over the ocean near Japan were retrieved from the polarization measurements by POLDER on board ADEOS Satellite. The optical thickness over the open sea area in the Pacific Ocean was small (<0.2) whereas that over the Japan Sea and near the Japan islands was large on April 26, 1997. The Angstrom coefficient also showed large difference between over the open sea area and near the land. These results suggest that degree of polarization measurements are useful for retrieving optical characteristics over the ocean.
