Based on the climatological calculating methods proposed in this paper, the net radiation, as well as the components of radiation balance, is computed for 223 stations throughout China and their distribution patterns are analyzed graphically. It is found that high-value centers of net radiation appear steadily in both the south of the Qinghai-Tibetan Plateau and the east of Inner-Mongolia while low-value centers in the Sichuan Guizhou Plateau. Annual variation patterns of net radiation in different places, especially the month when the peak value occurs, are closely associated with the coming time of the rainy season. The components of net radiation obtained from calculation have relative errors, on the average, of 2.7% for the global radiation, 4.0% for the surface albedo, 9.4% for the effective radiation, and 8.9% for the net radiation, respectively.
