Ground Water Data Access and Tools

NASA has ground water datasets that help researchers characterize the location and use of ground water . Access a range of data and data tools such as the GRACE(-FO) Data Analysis Tool, AppEEARS, and GRACE Python scripts to make the most of ground water data.

Featured Observation Method: GRACE

The NASA/German Space Agency (DLR) Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-on (GRACE-FO) platforms consists of two identical satellites that work together in orbit. The two satellites follow each other around the planet spaced 137 miles apart. Together hey measure differences in how Earth's gravity pulls on the satellites, which in turn can be used to reveal changes in the mass of water on and under the surface of Earth.

The GRACE satellites flew from March 2002 to October 2017 and GRACE–FO satellites have been in space since May 2018.
