摘要：

利用世界气候研究计划/全球能量与水循环试验(National Aeronautics and Space Administration/World Climate Research Program，NASA/WCRP)发布的长期地表辐射收支(Global Energy and Water Exchanges-Surface Radiation Budget，GEWEX-SRB)数据产品和中国气象局资料室的地面辐射数据产品，分别获得1984—2007年新疆维吾尔自治区地表全天空向下太阳短波辐射辐照度和地表全天空向下日总辐射曝辐量，对比分析两种数据从而确定卫星数据的精度；在此基础上，进一步分析新疆维吾尔自治区地面太阳辐射的时空分布特征。结果表明：基于GEWEX-SRB卫星观测资料反演的新疆维吾尔自治区太阳辐射明显比地面观测太阳辐射偏高约10%—30%，但两种数据反映的新疆维吾尔自治区太阳辐射的时空分布特征一致。在空间分布上，新疆维吾尔自治区太阳辐射呈明显的经向和纬向分布即太阳辐射由西北向东南方向逐渐递减；在时间分布上，太阳辐射从夏季、春季、秋季至冬季依次减小，从春季到冬季太阳辐射逐步由经向分布向纬向分布转变，夏季太阳辐射变化幅度最大，春季太阳辐射多年变化倾斜率增加最多，冬季太阳辐射多年变化倾斜率增加最少；太阳辐射月变化呈正态分布。

Abstract:

Based on the long-term data products of Global Energy and Water Exchanges-Surface Radiation Budget (GEWEX-SRB) released by the National Aeronautics and Space Administration/World Climate Research Program (NASA/WCRP) and the surface radiation dataset obtained from China Meteorological Administration (CMA), the surface downward solar radiation irradiance and the surface downward daily radiant exposure over the Xingjiang Uygur Autonomous Region from 1984 to 2007 were obtained to examine  the accuracy of the satellite dataand further investigate the spatiotemporal characteristics of the surface solar radiation in this region. It showed that the solar radiation retrieved by the GEWEX-SRB program is about 10%-30% larger than the observational values, but the satellite results and the observations of solar radiation show similar spatiotemporal characteristics. For the spatial distribution, the surface solar radiation in Xiangjiang Uygur Autonomous Region exhibits meridional and zonal  distribution, which means that the solar radiation decreases gradually from the northwest to the southeast. In terms of the temporal variation, the solar radiation is the highest in summer, followed subsequently by spring, autumn, and winter. The meridional distribution of the solar radiation in spring turns to a zonal distribution in winter. The change range of the solar radiation is the largest in summer. The  variation of  time slope of solar radiation for many years is the largest in spring and the least in winter. The monthly variation of solar radiation shows a normal distribution.
