Validation of FY-3B satellite temperature product

This paper developed a method of validation test research of domestic satellites LST products. The experimental data include high resolution landsat8 image, low resolution FY-3B and MOD11A1 LST product. The main steps of the method are as follows: (1) Three different algorithms for retrieving land surface temperature on landsat8 data. Through the comparative analysis of the results, we select an algorithm for subsequent verification. (2) Use the inversion result and MOD11A1 product to compare with FY-3B product respectively.(3) Use matlab to compute some parameters and curve data fit. The study results show that the FY-3B temperature product is similar with the others. It is available in a certain extent.
