Soil moisture is a key variable in terrestrial water cycle, playing a key role in the exchange of water and energy in the land-atmosphere interface. The spatiotemporal variations of soil moisture from multiple sources during 1988–2010 are evaluated against in situ observations in the Yellow River basin, China, including the Essential Climate Variable satellite’s passive microwave product (), ERA-Interim reanalysis (), the National Centers for Environmental Prediction/Department of Energy’s Reanalysis-2 (), and the Variable Infiltration Capacity model products (). The seasonal soil moisture dynamics of and appear to be consistent with , with significant soil drying in spring and wetting in summer. and , however, fail to capture the soil drying before rainy seasons. Remarkably, shows large agreement with in terms of the interannual variations and the long-term drying trends. captures the interannual variations but fails to have the long-term trends in . As for and , they fail to capture both the interannual variations and the long-term soil drying trends in .
