Abstract

This paper describes how to retrieve the optical properties of atmospheric aerosols over the ocean from ADEOS/POLDER measurements. POLDER provides the polarization and directional information of reflected light by the Earth's atmosphere and/or surface. The extracting algorithm for aerosols is based on the look-up table method. Our look-up table is compiled by multiple scattering simulations in an atmosphere-sea surface system. As result, global monthly mean aerosol properties, e.g. optical thickness of aerosols and Angstrom exponent, are obtained. It is found that the specific features of maritime aerosols are shown from our result. In addition, it seems that continental aerosols are blown over the ocean in April in the west Pacific Ocean and in the west coast of middle Africa. Our procedure is validated using the ship-based measurements.
