Transmissions at 0.75 and 1.65 μm can also be used to retrieve τ and re. 2. Study the impact of cloud inhomogeneity on the satellite retrieval simultaneously. Two 3D cloud fields, cumulus and stratocumulus fields are used in our study. The two cloud fields are generated with LES model and are adopted by the I3RC phase II. The BRDF at the wavelengths of 0.65 and 2.13 μm are calculated with SHDOM, and then the cloud optical thickness and effective particle radius are simultaneously retrieved using the MODIS algorithm. We studied the impact of cloud inhomogeneity on the satellite retrieval at high and medium resolutions. Some conclusions have been made, such as the BRDF abnormal phenomenon, the reverse relationship between τ and re, the clustering effect of over and under estimation in the retrieval of τ and re .

我们选用为I3RC所采用的由LES模式给出的具有明确物理属性的两个高分辨率三维云场－积云场与层积云场，利用SHDOM三维辐射传输模式来模拟卫星观测的辐射值，并采用MODIS算法进行反演，同时研究了在高分辨云场及中低分辨率云场下，云的非均匀性对反演云光学厚度及有效粒子半径的影响，并得到了云的非均匀性会造成的双向反射率异常，反演结果中光学厚度与有效粒子半径的负相关关系，高估或低估现象是成&簇&出现的等结论。

Based on the split window method, the classification of the ground land cover types, and the given spectral emissivities range in thermal infrared bands for each ground class and the fact that the actual land surface temperatures are the same for all thermal bands of MODIS, the land surface temperature were determined by means of maximum correlation and least square fit.

因此，本文在地表温度遥感定量反演的局地分裂窗算法的基础上，依据MODIS的多个热红外通道，其中的任意两个通道组合，通过分裂窗算法得到的地表温度都应该相等这样一个事实，在对地物进行分类的基础上，给定地物的波段比辐射率的范围，借助于两组温度之间的最大相关和最小方差，通过迭代的方式得到地表温度和分裂窗算法所使用的MODIS热红外通道的波段比辐射率。
