Retrieving atmospheric temperature profile (TP) data through satellite thermal radiative measurement has gained lots of attentions in recent years. These retrieved profiles may involve some uncertainties. Although different methods have been introduced to minimize these uncertainties, they are time consuming and complicated. This work, based on the available methods, presents an approach for improving the clear sky TP calculation in two stages. In the first stage, a radiosonde mean TP is introduced to the radiation transfer equation and the deviation from this profile is calculated. In the second stage, by correcting the slope of this new profile and then using this new slope and land surface temperature, the improved TP for each pixel in the scene is calculated. A comparison between the model output TP and the one measured by radiosonde in steps of 100 m shows root mean square errors between 0.38 and 3.86 K. This shows considerable improvement compared to the Moderate Resolution Imaging Spectroradiometer (MODIS) products. Copyright (C) 2010 Royal Meteorological Society
