Land Surface Temperature (LST), as a key parameter in environmental interaction, has been studied in several researches. Urban thermal condition depends on land cover types that composed of different materials with various thermal properties. In this study we analyzed diurnal temperature of vegetation, stone, water, cement, asphalt, and soil land cover types (LCT), as main components of urban structure. The Diurnal Temperature Cycle (DTC) method used to model daily behavior of different material temperature’s by implementation of precise sensors at a weather station in Tehran, of Iran. Then, comparisons between maximum diurnal temperatures of different LCT with LST at the day and night time of MODIS were conducted. Result showed that in warm days the discrepancies between materials were larger and soil, asphalt, and cement had higher temperatures than stone, vegetation, and water. Also, water had little fluctuations and some phase shift to reach maximum amplitude. Also, time series of MODIS LST in the study area were extracted and compared with maximum diurnal temperature of different LCT. Maximum correlation was estimated between Terra daytime LST and T_max of soil and cement material with 0.948 values for "R^2"  and 2.89 and 4.2^C"  for RMSE.
