Soil moisture plays an important role for understanding hydrology and climate. Soil moisture is a key variable in hydrological process, as the availability of moisture content in soil controls the mechanism between the land surface and atmospheric processes. Accurate estimation of soil moisture is crucial in environmental studies. Soil moisture can be measured by variety of remote sensing techniques. Combination of Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) can be used as indicator for surface soil moisture monitoring. For In situ measurements of soil moisture, the District Umarkot of Sindh was visited and a total of 24 samples were collected and analyzed. Soil moisture was calculated using the dry mass technique. Initial weight was carried out then the samples were heated at 105 °C for 18 hrs to calculate the dry weight. A relationship was be developed between ground and satellite based observed soil moisture measurements. Validation of satellite based and in situ measurement was carried out. It was found that maximum soil moisture for depths (0-15cm, 15-30cm, 30-45cm) is (19.80%, 19.20%, 21.20%) respectively.The relationship between satellite based soil moisture and in situ measurements was significant (R2>0.70).
