THE SPECTRAL MEASUREMENT OF THE SOLAR GLOBAL RADIATION ON TIBETAN PLATEAU DURING APRIL-OCTOBER

The distribution characteristics of the spectral radiation energy in the solar global radiation are discussed,and the effects by solar elevation and weather conditions on the relative flux of the solar spectral radiation are analyzed. Compared with those in the eastern plain of China,the relative flux of PAR on Tibetan Plateau is a little lower,but the absolute flux of PAR is far higher.
