摘要
地表温度是气象、水文、生态等研究领域中的一个重要参数。本文针对MOD IS数据的分裂窗算法进行了简要的介绍,并对参数的获取进行了分析。该算法已经被推荐并已经应用于中国地表温度产品生产。为了进行义务化流程生产地表温度产品,我们在IDL6.0环境下,编程实现了该算法。该程序运算速度快,操作简便,不需人为干预就可快速反演地表温度,非常适合批量计算MOIDS地表温度。
Land surface temperature （LST） is an important parameter in meteorology, hydrology, ecology and so on. At present,MODIS is widely used for LST retrieving , and the splits window algorithm is one of the most approved methods. Although the precision of this algorithm is quite high, it is difficult to operate on practical application because of its complexity. We have programmed this algorithm using IDL language, and realized the LST＇s retrieving automatically. The results indicate that this procedure is fast , easy to handle, and can be used for producing the LST products in hatches.
