Although a lot of rain fell on the Golden State this past week, NASA says that California will need 11 trillion gallons of water to end the drought throughout the state.
The darker the color, the more severe the drought conditions are in those locations. The dark red pretty much follows the Mojave desert that dumps out in the Los Angeles basin.
So it isn’t a big suprise that areas like Death Valley don’t have a lot of water in the first place.
The impressive part of this, is that NASA made this first every calculation based on satellite data, some from the Aqua satellite above.
“Spaceborne and airborne measurements of Earth’s changing shape, surface height and gravity field now allow us to measure and analyze key features of droughts better than ever before, including determining precisely when they begin and end and what their magnitude is at any moment in time.
Other NASA satellite data showed that the snowpack in California’s Sierra Nevada range is only half previous estimates. “The 2014 snowpack was one of the three lowest on record and the worst since 1977, when California’s population was half what it is now,” said Airborne Snow Observatory principal investigator Tom Painter.
