NASA Earth Observatory<\/a>: “The map above depicts changes in water storage on Earth\u2014on the surface, underground, and locked in ice and snow\u2014between 2002 and 2016. Shades of green represent areas where freshwater levels have increased, while browns depict areas where they have been depleted. Data were collected by the GRACE mission, which precisely measured the distance between twin spacecraft as they responded to changes in Earth’s gravity field. In sensing the subtle movements of mass around the planet, the satellites could decipher monthly variations in terrestrial water storage.” The GRACE<\/a> observations form the basis of a study published this month in\u00a0Nature<\/em><\/a> on changes in global fresh water availability.
