近20年卫星遥感资料在我国太阳能资源评估中的应用综述

Review of Applications of Satellite Remote Sensing Data to Solar Energy Resources Assessment in China in Recent 20 Years

卫星遥感资料的应用是提高太阳能资源评估时空分辨率的有效手段。我国从20世纪80年代中后期开始将卫星遥感资料应用于太阳能资源(地面太阳总辐射、直接辐射和散射辐射)的计算和评估中,至今已取得较大的进展,主要表现在两个方面:(1)卫星遥感资料的直接利用(统计反演法),(2)卫星遥感资料的间接利用(物理反演法)。通过对近20余年我国在这两个方面研究成果的总结和论述,说明卫星遥感资料在太阳能资源评估应用中的优点是提供了一种自上而下的、时空分辨率较高的观测资料,可以弥补当前地面气象观测站的不足,而难点则主要在于对云和气溶胶的处理还不够完善。

The applications of satellite data are effective methods for solar energy resources assessment. These methods were applied in China from the 1980s at two aspects,one is using satellite remote sensing data directly（Statistical Methods）,and the other is using satellite remote sensing data indirectly（Physical Methods）.With the summary of these two aspects,the advantages and difficult points of the satellite data application in solar energy resources assessment are discussed.It is considered that the observation method from above to below and the high resolution are the main advantages.However,the calculations of the influences of cloud and aerosol on surface radiation are the two difficulties.
