Aerosol optical properties are the key factors for direct radiative forcing. The aerosol optical properties and their variations were observed in four different regions of Beijing, Xianghe, Xinglong, and Dunhuang. The four different regions aerosol direct radiative forcing were calculated from the SBDART model based on the observed aerosol data. The results of quantitative relationship between the aerosol optical properties and aerosol radiative forcing efficiency were obtained with the comparative analysis of the four regions of aerosol radiative forcing. The results have important reference significance in analyzing climate models and evaluating environmental energy structure.
