Abstract
The Gravity Recovery and Climate Project (GRACE) is a collaboration of NASA and the German Aerospace Center that have been making detailed measurements of Earth's gravity since March 17, 2002. GRACE shows how mass is distributed around the planet and how it changes over time. Data from the twin satellites are made into monthly gravity maps that are very accurate. Changes in mass at a given location from month to month are inferred to represent groundwater storage changes in aquifers. To see how groundwater reservoirs change in the Sahara, Gobi Desert and Great Victoria Desert GRACE monthly data from April and November from 2002 to 2011 were examined using Geographic Information System (GIS). The GIS maps help show how groundwater storage changes seasonally, over time, and from location to location.
