Abstract在分析热红外遥感和现有的劈窗算法的理论基础上,针对MODIS数据对劈窗算法进行了推导。通过对热辐射强度和温度之间的关系计算,对Planck函数进行了线性简化,同时分析了MODIS的波段设置特点。MODIS的近红外波段适宜于反演大气水汽含量,而大气透过率主要从MODIS的近红外波段数据反演得到大气水汽含量,并进而根据水汽含量与大气透过率的关系来进行估算。通过MODIS的可见光波段、近红外和中红外波段数据,完全可以获得地表温度反演所需要的基本参数,从而形成了针对MODIS数据的地表温度反演的劈窗算法。最后以环渤海地区为实验区,对本文提出的方法进行了实际应用分析。
In this paper, the authors introduce the theory base of split-window algorithm and make a derivation for the split-window algorithm. As to the characters of the MODIS bands, the authors make a simplification for the Planck function. For the two main parameters of the split algorithm, the authors obtain them from the same image. Finally the authors retrieve the LST of Huanbohai region by using MODIS data and get the spatial distribution of LST in this region and make some analysis for the retrieval results.
