The maximum land surface temperature related to hot and dry climatic condition, Clear sky causes that the highest radiation reaches to the land surface and land surface warms up fast during day time. Lut Desert seems ideal condition for studying and determining land surface temperature and model development. Therefore in this study, 12 NOAA-AVHRR and MODIS data and air temperature data were used to evaluate the model of land surface temperature of Yardang region in Lut Desert. To study the LST model, 8 ground measurements as ground truth were used. From the results obtained from this research. We concluded that in spite of some difficulties in estimating land surface temperatures, we can extract valuable information from surface features. We may also conclude that accurate emissivities are necessary to study surface features and soils and to monitor surface changes.
