| Abstract: | This paper analyzes the key factors that result in the estimation errors of the MODIS land surface temperature products.Then the principle methods of validating the MODIS LST was discussed and compared.Normally there are bigger uncertainties of MODIS LST products in the semi-arid and arid regions.As a case study,the Heihe river basin was selected to estimate the accuracy of MODIS LST products in Chinese arid and semi-arid regions.The two kinds of ground-measured observation data were obtained from the autom... |
