New satellite imagers with better characteristics in spatial-temporal resolution and spectral coverage have been launched in recent several years. With such improved technologies, new satellite inversion algorithms have been developed and applied to the retrieval of aerosols, ocean color, clouds, and surface solar radiation, based on a series of sophisticated schemes, such as the use of coupled atmosphere-ocean radiative transfer model in the atmospheric correction for ocean color, the combination of radiative transfer model and machine learning techniques in the aerosols, clouds, and solar radiation estimation. In this talk, we like to introduce some new results by using the data from GOSAT-2/CAI-2, FY-3D/MERSI, GCOM-C/SGLI, Himawari-8/AHI, Sentinel-5/TROPOMI.
