| 摘 要： | 利用CERES SSF Aqua MODIS Edition 3A数据对新疆地区2003-2015年的13时至17时的地面短波向下辐射变化进行研究，得到了新疆地区近13年的地面短波向下辐射时空分布特征。可以发现，该地区地面短波向下辐射从东南向西北随着纬度的增加而逐渐减少，从春季到冬季，地面短波向下辐射逐渐地由经向分布向纬向分布转变，秋季变化幅度为全年最大，夏季最小。年变化呈现单峰趋势，接近正态分布，最大值出现在2004年5月13时。在日变化中，13时最大。新疆地区近13年整体来说，地面地面短波向下辐射呈现下降趋势，以13.3 W?m-2/10a的速率减小。春季变化呈现增大趋势，其余各季均为减小趋势。

| Abstract: | The spatial and temporal distributions of surface shortwave solar radiation in Xinjiang during 13h-17h, 2003-2015 are analyzed based on CERES data. The results show that the solar radiation reduces from southeast to northwest gradually as latitude increases. From spring to winter, the spatial distribution of solar radiation in Xinjiang changes from meridional distribution to zonal distribution. autumn change rate of annual maximum and minimum in summer.Annually variation shows single peak trend, close to the normal distribution with the maximum value appearing at 13 in May 2004. In the diurnal variation, the maximum is 13, and the minimum is 17, showing the law of decreasing from 13 to 17,.In recent 13 years, the whole area of Xinjiang has shown a downward trend, with the rate of 13.3 W?m-2/10a decreasing.The change trend decreases in spring and increase in the rest seasons. |
