Abstract: In order to know the solar energy resources scientifically and the relationship between the ground measured meteorological data and satellite data, using remote sensing and GIS technology, the author analyzed the solar resource in Qaidam Basin which was the most abundant area in Qinghai. The study contrasted the satellite data with observations data which based on infrared and visible light, then checked the model. The results showed that the inversion of remote sensing data and the variation of measured value were consistent, the correlation coefficient surpassed 90% . To calculate the total radiation by using the geostationary meteorological satellite FY2C data, it not only solved the problem which the climate model could not do, but also improved the spatial accuracy of quantitative research on total radiation.
