Abstract Land surface temperature (LST) is a vital parameter controlling the energy and water balance between atmosphere and land surface. LST image with high spatial resolution compatible with visible bands of Landsat TM is very important for the application of the LST image to many studies such as environmental monitoring. This paper examines the accuracy and applicability of two widely-used models for decomposition of LST images: SUTM and E-Distrad. Landsat TM data acquired in Beijing were used for the study. LST retrieved by the mono-window algorithm (MWA) was used to compare the LST decomposition images by the two models. The results achieved by the authors indicate that SUTM is more applicable than E-Distrad in the regions with low vegetation cover and high LST such as downtown, while the latter is better than the former in the high vegetation cover and relatively cold areas such as water bodies. The RMSE and MAE are 1.522 K and 1.191 K respectively for SUTM and 1.768 K and 1.173 K for E-Distrad. It is thus concluded that both models are applicable for decomposition of LST images for high spatial resolution, but the results of decomposition are different in areas of different vegetation covers.
