In this study, the spatial pattern and correlation of surface moisture content over the Jinghe River Basin, was investigated by using in-situ measurements and remotely sensed data. First of all, the spatial pattern of the soil moisture content was retrieved from the MODIS imagery based on a statistical relationship between the Temperature Vegetation Dryness Index (TVDI) and in-situ soil moisture measurements...
Detailed vertical soil moisture profile is essential for hydrological modeling and is also often used as important diagnostic information for better understanding the surface-atmospheric interactions. This paper presents a modified ESSI distributed hydrological model that is suitable for comparing and assimilating the remotely sensed soil moisture by integrating a soil water parameterization scheme...
Both passive and active microwave sensors have long been used in retrieving the soil moisture, however, only the SAR can provide the high spatial resolution data (10 m~1 km) suitable for watershed scale hydrological studies. In this paper, we took a preliminary study on deriving the catchment scale soil moisture content and their spatial variations in a typical semi-arid rangeland located at the Loess...
