The calculating method of global radiation and surface temperature on the roadbed of the Qinghai-Xizang Railway is improved by analyzing the experiment data observed on roadbeds with different railway directions at Wuli. In order to apply this method to all roadbed of the Qinghai-Xizang Railway, a statistical correlaion of calculating parameters with roadbed location and elevation is set up. The long term date series of GAME-Tibet (GAME experiment of engine and water cycle in the Tibetan Plateau which was implemented under the cooperation project between two sides of China and Japan) obtained from the observation site along the Qinghai-Xizang Railway is involved to develop the method.
