%X We analyzed the characteristics of planetary albedo of visible channels and infrared channel brightness temperature data from FY serials meteorological satellites at the source of the three rivers. This study considered the effects of clouds, aerosols, vapor, and altitude on radiation transfer processes and established a horizontal direct radiation, scattering radiation and total radiation calculation model. Based on the Debieu model, we considered the effects of elevation, aerosol, water vapor and other factors on the clear day surface solar total radiation at the source of the three rivers, and compared these with actual measured values from ground radiation stations. We found that the change in actual measured values and simulative remote sensing values was consistent; the correlation coefficient was higher than 0.90. Daily mean variance was 10%. Differences between the actual measured value and simulative remote sensing value were within 5% and the absolute difference was within 2 MJ/m2 on an overcast day. The total solar radiation of hours showed a parabolic curve on time scales. The total solar radiation of hours reached the maximum in 13h and the minimum in 19h. Daily solar radiation variation showed that the daily maximum solar radiation value was 42.50MJ/m2, and the daily minimum was 1.38MJ/m2. The total solar radiation of hours is zero in 20h. Solar radiation was in the range of (500~800)MJ/m2 and the largest solar radiation value was for June. The spatial distribution of the surface solar total radiation ecreased from east to west. Distribution of maximum solar total radiation is in the Kekexili area, and the minimum solar total radiation is in southeast part of our study area. Because of the richest areas of solar energy, easier transport, a complete photovoltaic industry chain, utilization of solar energy market and national policy, there remains great potential for the development and utilization or solar energy in the three rivers source area. Studies such as ours can drive the expanded use of clean energy.
