摘要：Atmospheric aerosols play an important role not only in the climate research but also in the remote sensing of the Earth surface. This work focuses on the retrieval procedure for such aerosol properties as optical thickness, Angstrom exponent and single scattering albedo with the Second Global Imager (SGLI) on Japanese Global Change Observation Mission - Climate satellite (GCOM-C). The SGLI is designed to observe atmosphere, land, and ocean in total by using 18 channels from near ultra violet to thermal infrared spectra. One of the interesting features of SGLI is to measure the polarization of reflectance from Earth with long track tilting angles covering +/- 45 degrees. Our algorithm is based on the efficient usage of this polarization information as well as radiance measurements. Namely aerosol optical thickness (AOT) and its wavelength tendency are derived by combination use of polarization and radiance with two-channel algorithm. In addition it is known that the carbonaceous aerosol is an unknown item for climate modelling. Here the retrieval algorithm for carbonaceous particles is especially focused by using the near UV measurements. Our algorithms are validated with the data given by POLDER and GLI sensors equipped on the satellite ADEOS-II
