The land surface temperature (LST) products of the MODIS were validated in this research based on the measured daily mean soil surface temperature extracted by averaging the minimum and maximum soil surface temperature data during 2013-2014 time period for Sararoud station located in the West of Iran. The agreement between MODIS and measured LST data was validated by considering the coefficient of determination (R2). With respect to that there are four products from Aqua and Terra satellites including LST_day-aqua, LST_night-aqua , LST_day-terra and LST_night-terra, different combinations of these products were considered as the possible candidates of the daily mean of LST and the best case with the higher value of R2 was recognized and considered as the daily mean of LST. The results showed that by averaging of the LST_night-aqua, LST_day-terra and LST_night-terra and considering it as the mean daily of LST, the higher agreement between measured and MODIS LST data is occurred with a R2 value of 0.93.
