NASA Satellites Find Freshwater Losses in Middle East

Variations in total water storage from normal (in millimeters) in the Tigris and Euphrates river basins, as measured by NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites, from January 2003 through December 2009. Reds represent drier conditions, while blues represent wetter conditions. The majority of the water lost was due to reductions in […]
