Validation of SMOS, SMAP, and ESA CCI Soil Moisture Over a Humid Region

With recent advances in satellite microwave soil moisture estimation, there is a demand for up-to-date validation of satellite soil moisture products. This article presents a sparse network validation over a humid region within the Laurentian Great Lakes basin for five state-of-the-art satellite soi...
