Net surface shortwave radiation (NSSR) with high temporal and spatial resolutions is of great significance to studies of the Earth surface radiation budget,climate change,and some other relevant fields. However,most of the present investigations on the estimation of NSSR focus on the polar-orbit satellite observations which have only one or two images available for a given study area. This study primarily develops a method for obtaining NSSR by directly using the geostationary satellite data,and we provide multi-temporal NSSR estimates in regional scale using the Chinese operational geostationary meteorological satellite FengYun-2E (FY-2E) data. Results indicate a very significant correlation between our estimated NSSR and the tower-based NSSR measurements with the coefficient of determination (R~2) of 0.99 and a root mean square error (RMSE) of 27.51 W/m~2. The R~2 value is 0.99 and RMSE is 15.36 W/m~2,excluding winter. This indicates that NSSR can be estimated by using the proposed method which benefits climate change and some other fields at the regional scale with high temporal resolution.
