内容 研究概要:The satellite image data, measured by ADEOS/POLDER, ADEOS/OCTS and NOAA/AVHRR, were used to retrieve aerosol optical parameters. We examined two methods for retrieving local aerosol optical parameters using the ADEOS/POLDER data by comparing with the validation data. The first method is based on a R-P (Reflectance-Polarization) algorithm using both multi-directional reflectance and multi-directional polarization information in 865nm band. The second method is based on a R-R (Reflectance-Reflectance) algorithm using only multidirectional reflectance information in two infrared bands (670nm and 865nm). We found that the former gives better agreement with the measured sky validation data than the latter. Furthermore, the retrieval results by the R-R algorithm using the mono-directional reflectance data of ADEOS/OCTS and NOAA/AVHRR were compared with those of ADEOS/POLDER, based on the R-P algorithm. Although we had a relatively good agreement in the aerosol optical thickness among these algorithms, we found that the retrieval results of Angstrom exponent are not reliable in the cases of the R-R algorithm using the reflectance data alone.
