摘要

本文提出了一种基于水汽和原位数据的局部地表温度反演方法，并在盈科地区进行了应用。利用MODIS/Terra Level-1b数据反演地表温度，模拟地表辐射率和水汽。利用ASTER温度产物与MODIS检索结果进行比较。MODIS反演结果与ASTER数据吻合，平均差值为1.64K。

Localized land surface temperature retrieval from the MODIS Level-1b data using water vapor and in situ data

In this paper, we proposed a localized land surface temperature retrieval method using water vapor and in situ data, and applied it in Yingke area. With the ground measurement of emissivity and water vapor simulated, we recovered LST from MODIS/Terra Level-1b data. ASTER temperature product was used to compare with the MODIS retrieval result. The comparison showed the MODIS retrieval result agreed with ASTER data with an average difference of 1.64K.
