劈窗算法是目前由热红外遥感图像数据获取陆面温度最主要的方法。由于进行地面像元尺度实时陆面温度同步测量的困难，尚无法直接对现有各劈窗算法进行评判。该文借助于辐射传输模型ＬＯＷＴＲＡＮ７及其提供的６ 种标准大气模式，进行模拟计算，分析了６ 种主要劈窗算法对大气廓线误差和比辐射率的敏感度，作为对劈窗算法适用性的一间接判据。
Split-window algorithm is currently the most important method to obtain the temperature of the land surface from thermal infrared remote sensing image data. Due to the difficulty of real-time measurement of land surface temperature on the ground pixel scale, it is still not possible to directly evaluate the existing split-window algorithms. In this paper, by means of the radiation transmission model LOWTRAN7 and its six standard atmospheric modes, the simulation calculation is carried out. The sensitivity of the six main splitting window algorithms to the atmospheric profile error and emissivity is analyzed. Applicability of an indirect basis.
