　　報(bào)告內(nèi)容：The IPCC has identified aerosols as among the most uncertainty factors to radiative forcing. Since the ocean covers more than 70% of the Earth’s surface, it is dispensable to estimate the aerosol loading over the ocean. Even though the contributions from the aerosol account for a large proportion of satellite signals in the atmosphere-ocean system, there is still about 50% discrepancy of the mean aerosol optical thickness from several prominent aerosol products provided by the satellite instruments. In this talk, I shall present our recent work related to the developments of a new remote sensing algorithm for the simultaneous retrieval of aerosol optical properties and water leaving radiance over the open and costal ocean using multispectral information, as well as an oceanic radiative transfer model and an acceleration scheme from the Neutral Network method. Finally, a promising scheme considering the spatial smoothness constraints for the aerosol retrieval, i.e., multi-pixel scheme, which has and will be used in current and next Japan carbon satellite instruments GOSAT_CAI / GOSAT2_CAI2, will be also introduced.
