This illustration shows terrestrial water storage changes in global endorheic basins from GRACE satellite observations, April 2002 to March 2016. In the top image, terrestrial water storage trends -- in millimeters of equivalent water thickness per year -- for each endorheic unit are highlighted, followed by animated monthly terrestrial water storage anomalies, also in millimeters. The bottom image shows monthly net terrestrial water storage anomalies in gigatonnes, in global endorheic and exorheic systems -- excluding Greenland, Antarctica and the oceans -- and linkage to the El Niño-Southern Oscillation, right axis. Terrestrial water storage anomalies are relative to the time-mean baseline in each unit or system, with removal of seasonality. For comparison, 360 gigatonnes of terrestrial water storage equals 1 millimeter of sea level equivalent. Courtesy of Jida Wang.
