Radiative transfer processes are one of the important physical processes in the atmospheric-oceanic systems. Accurate calculations of radiative transfer in the atmospheric-oceanic systems are essential for studies on the energy balance of the Earth-atmosphere system, climate change research, and remote sensing detection of oceanic resources. In this study, a new oceanic radiative transfer model was first developed, and an atmospheric-oceanic coupled radiative transfer model was established, overcoming the challenge of accurately simulating key parameters in the coupled system. Based on this, a high-precision synchronous remote sensing algorithm for atmospheric aerosols and ocean color was constructed, addressing the issue of large retrieval errors for aerosol and ocean color information in complex backgrounds. Furthermore, a remote sensing algorithm for cloud microphysical parameters based on infrared channels was developed, breaking through the difficulty of retrieving cloud parameters in the oceanic glint area. Finally, combining aerosol and cloud parameter information, an algorithm for estimating solar shortwave radiation was developed, achieving high-precision remote sensing detection of solar shortwave radiation and component information under all-weather conditions, serving climate change and solar energy resource assessment research.
