 The paper compares three different methods for land surface temperature, LST, inversion from Landsat 8 thermal infrared sensor, TERS, including radiative transfer equation-based, split-window algorithm and single-channel method. The radiative transfer equation-based method using band 10 has the highest accuracy with RMSE lower than 1K, while the SW algorithm has moderate accuracy and the SC method has the lowest accuracy.
