摘要：

This paper addressed the evaluation of Temperature Independent Spectral Indices of Emissivity (TISIE) in Land Surface Emissivity (LSE) retrievals over an eastern China area (110 degrees E-125 degrees E, 35 degrees N-50 degrees N) using Radiative Transfer Modeling (RTM) experiments with the products (MOD11C1, MOD11_L2 and MOD07) of the MODerate resolution Imaging Spectroradiometer (MODIS) on Terra in Sept. of 2007. The results show that the LSE errors due to the instrumental noises can be neglected, whereas the LSE errors due to the method and the uncertainties of Total Precipitable Water (TPW) are channel-dependent and region-dependent, and in general, they are so large that they cannot be neglected in both middle infrared and thermal infrared channels.
