Aerosols and clouds influence Earth’s radiative energy budget, but their regional impacts remain insufficiently understood. This study investigates the spatial distribution patterns long-term trends of fluxes over China from March 2000 to February 2023 using CERES-SYN data. Notable decreasing in net at top atmosphere (−0.38 W m−2 year−1) surface (−0.35 during period have been observed. Cloud properties aerosol MERRA-2 are used assess aerosols on flux variations. Results show that primary drivers variations across China, while cloud changes exert notable regionally dependent influences. In southern reductions black carbon organic substantially variations, along with contributions mid-high, mid-low, low clouds. northern decreases dust primarily drive trends. Over Tibetan Plateau, mid-high predominantly affect changes. Xinjiang Inner Mongolia, fluctuations high, mid-low clouds, sulfate aerosols, jointly contribute although overall relatively small.
