Soil Moisture & Ocean Salinity (SMOS) Satellite Data

The SMOS satellite is a polar orbiting satellite operated by the European Space Agency. The satellite provides estimates of soil moisture in the approximate top 5 centimeters of soil and the amount of vegetation on the land surface. Dr Brian Hornbuckle leads a local research team here at Iowa State that works with this data. The IEM collects processed data from this satellite, generates analysis plots, and makes the raw data available.
