Abstract:

The spatiotemporal distribution of total solar radiation at 11 meteorological stations in Xinjiang was studies based on analyzing the data of solar radiation recorded in 2017 at minute scale. The results showed that the curve of daily variation of total solar radiation was unimodal, and the daily sunshine duration was the highest (about 17 hours) in summer, then that in spring and autumn (about 14 and 15 hours respectively), and it was the lowest (about 12 hours only) in winter. Regionally and seasonally, the maximum value (589.61 W?m-2) occurred in Hotan in spring, and the minimum one (102.29 W?m-2 only) in Urumqi in winter. The spatial distribution of satellite retrieval radiation showed that the irradiation in south Xinjiang was obviously higher than that in north Xinjiang, the average irradiation in summer was the most similar to the annual average irradiance, then in winter, the difference between north Xinjiang and south Xinjiang was not significant, and the seasonal difference was the lowest in Aksu. The fitting analysis of satellite and surface radiation data revealed that the F value in south Xinjiang was as high as 6 215.53, that is, under the condition of clear sky, the retrieval of CERES/SSF satellite data in south Xinjiang was better than that in north Xinjiang and the Turpan-Hami Basin.
