NASA Expands Groundwater Maps Globally to Help Reveal Remote Droughts

NASA expands groundwater maps globally to help reveal remote droughts:
The global maps are made possible by the Gravity Recovery and Climate Experiment Follow On (GRACE-FO) satellites from NASA and the German Research Center for Geoscience. The data from these satellites, which took over for the original GRACE satellite mission that ended in 2017, is combined with other data and computer models to show simulations of energy and water cycles around the world.
The results of this are three layers of ground moisture data: surface soil moisture, root zone moisture, and shallow groundwater. With these, experts can monitor groundwater conditions around the world, identify areas that are likely to be hit hard by droughts, and more. This is particularly important for countries that do not possess any of their own infrastructure for monitoring groundwater.
