Abstract :
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 1.64 K.
