A method for surface temperature retrieval with ASTER/TIR

摘要

A method of surface temperature retrieval ASTER/TIR (Advanced Spaceborne Thermal Emission and Reflection Radiometer/Thermal Infrared Radiometer), in terms of atmospheric correction of the ASTER/TIR data is proposed. The results from a simulation study on surface temperature estimation accuracy using a split window type of algorithm show around 1.2 K of final prediction error. Linearized inversion (radiative transfer equation is approximated in the form of linear equation) and nonlinear iteration (nonlinear radiative transfer equation will be solved in iterative basis) should be developed in order to improve estimation accuracy.
