Polarimetric properties of atmospheric aerosols

This work presents an aerosol model interpreting photopolarimetric measurements of skylight over the ocean. Polarization degree and optical thickness of the atmospheric constituents have been simultaneously measured by a photopolarimeter, whose spectral bands are set up to correspond to the ADEOS/POLDER. Our algorithms are based on light scattering simulations of the polarization field. It is shown that such a Maxwell-Garnett mixing rule as small water-soluble inclusions is an oceanic matrix is available to interpret the polarization measurements over the Seto Inland sea and its volume fraction of inclusions to matrix varies with time polarimetric properties of atmospheric aerosols, and that magnitude of polarization degree is reduced due to multiple scattered light, especially in the visible wavelengths.
