Abstract: Based on the observation data from the China Pamir Plateau Land-Atmosphere Interaction Observation Station from July2016 to July 2021,this study selected indicators such as total radiation,scattering radiation,and direct radiation to investigate the variations and influencing factors of solar total radiation and scattering radiation balance in the region. The results show that the annual exposure of solar total radiation,scattering radiation,and horizontal direct radiation in the China Pamir Plateau is 6474.41,2219.95,and 3497.35 MJ/m2,respectively. Among them,the highest irradiance for total radiation,scattering radiation,and horizontal direct radiation in a year is 1171.18,676.23,and 1003.52 W/m2,respectively,occurring on July 23,2017,May 31,2017,and April 3,2017. The peak values of the average irradiance for total radiation,scattering radiation,and horizontal direct radiation are 690.85,218.66,and 417.02 W/m2,respectively,appearing around 12:00. The mean surface albedo of the China Pamir Plateau is between 0.24and 0.49,with an annual average of 0.30. Precipitation and dust weather have an impact on the surface radiation balance. Among them,precipitation reduces the daily peak average irradiance of total radiation by about 18% compared to sunny days,increases the daily peak average irradiance of scattering radiation by about 1.8 times. When sand or dust weather occurs,the daily peak irradiance of total radiation does not change much compared to sunny days,but the daily peak average irradiance of scattering radiation increases by about1.8 times. In addition,when sandstorms occur around Kashi City,the scattering radiation irradiance and daily exposure radiation in the China Pamir Plateau significantly increase.
