散射粒子的检索算法示出的基础上，在海洋上空的天空光和多个散射模拟的偏振场的polarimeric测量。大气成分的偏振分量已被一台光谱波段设置为对应于ADEOS/POLDER的偏振仪（命名为PSR 1000）测量。POLDER是卫星上第一个用于观测偏振的传感器，结果表明非均匀颗粒比均匀颗粒更能解释大气气溶胶的偏振特性，海洋基质中小水溶性包裹体的Maxwell-Garnett混合规则可用于解释濑户内海大气气溶胶的偏振测量。我们还发现，在我们的观测过程中，气溶胶的折射率值，即，其化学成分随时间和地点而变化，而不是颗粒大小。
Retrieval algorithms for scattering particles are shown based on photopolarimeric measurements of sky light over the ocean and multiple scattering simulations of the polarization field. Polarized components of the atmospheric constituents have been measured by a photopolarimeter (named PSR1000) with spectral bands set up to correspond to the ADEOS/POLDER. The POLDER is the first sensor on board the satellite to be designed to observe polarization.It is shown that heterogeneous grains are better than homogeneous models to explain polarimetric properties of atmospheric aerosols, and a Maxwell-Garnett mixing rule for small water-soluble (WS) inclusions in an oceanic (OC) matrix is available to interpret the polarization measurements of atmospheric aerosols over the Seto Inland Sea. We also found during our observations that the value of refractive index of the aerosol, i.e., its chemical composition, varies with time and place rather than particle size.
