Interpretive Summary:
Technical Abstract: Within the next five years two satellites will be launched that are designed specifically to map and monitor global soil moisture. Each of these is an exploratory mission and a step toward an operational satellite. Each satellite uses highly innovative but different technologies. The first of these will be the European Space Agency Soil Moisture Ocean Salinity (SMOS) mission scheduled for 2007. SMOS will use synthetic aperture radiometry to achieve a moderate spatial resolution. If successful this technology can be extended to even higher spatial resolutions. The second satellite is the Hydrosphere State Mission (Hydros), which is part of the National Aeronautics and Space Administration (NASA) Earth System Science Pathfinder Program (ESSP). The objective of the mission is to provide global measurements of the earth’s soil moisture at 10-km resolution with two- to three-days revisit and land-surface freeze/thaw conditions at 3-km resolution with one- to two-days revisit.
