摘要: 采用2017年辐射数据,研究了新疆11个地面观测站点的太阳总辐射时空分布特征,发现总辐射辐照度日变化呈单峰分布,日照时数夏季最高,约17 h,春秋季次之,分别为14 h、15 h,冬季最小,仅为12 h;季节平均最大值出现在和田的春季,为589.61 W·m-2,最小仅约为102.29 W·m-2,出现在乌鲁木齐的冬季。卫星反演辐射空间分布特征显示:春季南疆辐照度明显高于北疆,夏季平均辐照度分布与全年最为相似,冬季次之,秋季南北疆差异不大,季节差异在阿克苏最小。从卫星和地面辐射数据的拟合分析可见,方差分析中南疆F值均较高,最高达6 215.53,即晴空条件下,CERES/SSF(Clouds and the Earth’s Radiant Energy System/Single Satellite Footprint)卫星资料在南疆的反演效果优于北疆及吐—哈盆地。

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.
