Watching Water Loss Via Satellite

NASA satellites have tracked the loss of water in California's Central Valley over the past few years, and finds that drought coupled with over-irrigation are stressing the state's supplies.

"The data comes from the Grace mission which detects changes in gravity caused by water as it cycles between the sea, the atmosphere and the land.

It illustrates the impact of a drought but also excessive irrigation use.

'The numbers we're getting out of this analysis point to groundwater use at unsustainable rates,' said Professor Jay Famiglietti of the University of California, Irvine."
