✦ Synopsis

In this paper, a rigorous radiative transfer mode1 (MODTRAN3) is used to simulate the radiance reaching Landsat TM band 6 for 10 different atmospheric profiles. The characteristics of the error in estimated surface temperature ranging from -30" to 0°C is analysed. The results show that the error depends on the atmospheric temperature, humidity structure and the surface temperature itself. The existence of a temperature inversion may reduce the error through the combined effect on the atmospheric thermal emission and the atmospheric absorption of surface emission. The relations between the error, the precipitable water content and the surface air temperature can be fitted adequately by polynomial equations.
