Using Remote Sensing to Measure the Affect of Drought on Ground Water
Scientists at NASA’s Goddard Space Flight Center have been experimenting with a new data product to assess groundwater and soil moisture drought indicators. The maps produced are used by the U.S. Drought Monitor and use data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites. In 2002, the GRACE satellites were launched […]
