The error analysis of the T/E separation relevant to the atmospheric correction error of the remotely sensed TIR data Original Research Article

For the surface temperature and emissivity estimation (T/E separation) from the remotely sensed multispectral thermal infrared (TIR) radiation, the atmospheric correction using the auxiliary atmospheric profile data is required. Such profile, for example the numerical forecast model output, is supposed to contain the error and affect the output surface temperature and emissivity accuracy. This paper describes the analytical relationship between the input error of the T/E separation (atmospheric correction error) and the output error (the surface temperature and emissivity error).
