Description Soil moisture is an important agricultural, meteorological and hydrological parameter. Despite of its imp ortance it is not easy to have the soil moisture observation continuously in large area. But it becomes possible to be monitored effectively and conveniently by remote sensing. Observed soil moisture data and MODIS data of MOD11A2 and MOD13A2, for the months of May, July and October (2007-2010) were used. GanSu Province and XinJiang Uygur Autonomous Region in China were chosen as a study area. Temperature Vegetation Dryness Index (TVDI) was derived using Normalized Difference Vegetation Index (NDVI) product MOD13A2 and Land Surface Temperature (LST) product MOD11A2. TVDI was incorporated in equation so as to derive relative soil moisture. In this study soil moisture data of 98 stations, of 10 cm depth were used. 75 stations were used to simulate the model and data of 23 stations were used for validation/comparison of results. Average relative error in simulated soil moisture is 29. 43 %.
