摘要
An established climatic calculation scheme for estimating the components of surface radiation budget is conducted at 223 stations throughout the country. The spatial patterns of net radiation (NR) and its components suggest that the high-value belt is steadily situated over the Yarlung Zangbo Basin in the south- ern Qinghai-Xizang Plateau and over the eastern Inner Mongolian Plateau, with the low-value belt over Sichuan-Guizhou mountainous terrain. The pattern changes a little with the transition of seasons. Tem- porally, the NR's annual changes, especially its maximizing month, are closely related to the coming of rainy season. The relative computation error is 2.7% for global radiation (GR). 4.0% for surface albedo (SA), 9.4% for effective radiation (ER), and 8.9% for NR.
