Abstract

This work shows how to estimate the characteristics of atmospheric aerosols using space-based observations of polarization and radiance taken by POLDER equipped on the satellite ADEOS. The retrieval algorithms for aerosols are based on light scattering simulations of polarization field. The model aerosol has taken into account the heterogeneous grain model with Maxwell-Garnett mixing rule for typical oceanic and water-soluble aerosol models. It is found that polarization information is useful to retrieve aerosol properties. As a result, aerosol distribution over the Pacific ocean near Japan is obtained, and we found that aerosol characteristics change in temporal and regional scales.
