Simulation results were used to estimate the effect of updates, performed in the period of 2007-2011 in molecular absorption models, on results of the atmospheric correction of satellite IR measurements in the atmospheric transparency windows. The simulation results show that, when no contribution of surface-reflected solar radiation is present, the effect of these updates on retrievals of the land surface temperature is significant only in the spectral range 3.5-4μm and is less than 0.6-1.3°K.
