POLDERデータを用いたエアロゾル特性の導出

2.OCTSデータとの複合利用

抄録

This paper proposes a procedure how to determine aerosol characteristics by referring to both of radiance and polarization. Our algorithms come from an idea that aerosol characteristics can be estimated in terms of scattering behavior in the polarization field.
At first it is shown that a heterogeneous grain model according to Maxwell-Garnett mixing rule as small water-soluble (WS) inclusions in an oceanic (OC) matrix is available to interpret ADEOS/OCTS and POLDER data observed over the Arabian Sea. Then atmospheric correction, which is based on radiative transfer process in an atmosphere-ocean model involving the retrieved heterogeneous aerosol model, is applied to ocean color data given by ADEOS/OCTS. Finally our atmospheric correction provides an expected chlorophyll map near the sea surface.
It is of interest to mention that retrieval algorithms for atmospheric aerosols are improved by combination use of radiance and polarization.
