Abstract: Based on the theory of the radiation transfer and some physical approximation techniques, a numerical climatological method for the radiation budget in the troposphere over China is proposed.Utilizing tenyears-averaged climatological data (1960-1969, 1961-1970) from 104 stations, the radiation budget and its components of the troposphere over China are calculated. In contrast with the satellite observations and other computational results, the results are satisfactory. The main factors which determine the budget were also discussed briefly.
