Validation of Soil Moisture and Ocean Salinity (SMOS) Soil Moisture Over Watershed Networks in the U.S
2012
IEEE Transactions on Geoscience and Remote Sensing
Preserved Fulltext
In this paper, we contribute to the validation of SMOS using a set of four in situ soil moisture networks located in the U.S. ...
The most recent source of soil moisture is the European Space Agency Soil Moisture and Ocean Salinity (SMOS) mission. ...
Each network is located in a different climatic region of the U.S., and each provides estimates of the average soil moisture over an area approximately the size a SMOS footprint. ...
