Spatio-temporal variation of surface soil moisture over the Yellow River basin during 1961–2012

Spatio-temporal variation of surface soil moisture over the Yellow River basin during 1961–2012

Soil moisture plays a significant role in agricultural and ecosystem development. However, in the real world soil moisture data are very limited due to many factors. VIC-3L model, as a semi-distribution hydrological model, can potentially provide valuable information regarding soil moisture. In this...
