NEW RETRIEVAL METHOD FOR AEROSOL OPTICAL PARAMETERS USING DIRECTIONAL REFLECTANCE AND POLARIZATION DATA BY POLDER ON BOARD ADEOS

We proposed a new retrieval method for aerosol's real part of refractive index, optical thickness, and Angstrom exponent using POLDER's directional reflectance and polarization data. We showed that aerosol's real part of refractive index can be retrieved systematically using multi-directional PR(polarization and reflectance) diagrams in a single infrared band by our algorithm for the first time. We examined the retrieved results, by comparing with the simultaneously measured sky observation data at the study site and we obtained a reasonable agreement between them.
