　　报告人简介：石崇，2015年中科院大气物理研究所博士毕业。研究方向为大气海洋系统辐射模式的开发及遥感应用。2015年9月至今在日本宇宙航空研究开发机构（JAXA）地球观测研究中心（EORC）工作，主要负责GOSAT及GOSAT2海域气溶胶遥感算法的开发及应用研究。

　　报告内容：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.
