NASA scientists say satellite remote sensing can help determine when water will fall from the sky several weeks in advance. It can pinpoint how much water is available in snowpack and how much water is available in the ground. It’s crucial information during California’s drought.
Duane Waliser is a research scientist at NASA’s Jet Propulsion Laboratory. He’s using satellite remote sensing to predict a tropical weather pattern that produces heavy precipitation. It’s known as an “atmospheric river.”
“One of these rivers transports as much water at any given time as about five to ten Mississippi Rivers, so it’s very significant, and about 20-to-30 percent of that often ends up in the form of precipitation.”
Scientists can now forecast the weather pattern as much as four weeks in advance. The Department of Water Resources says the information will help the state better prepare and respond during droughts.
The annual report on California's Air Quality has just been released, and the drought is listed as a major factor this year.
Rain and snow may not have pushed California out of its drought, but the late season precipitation will mean a little more water for State Water Project users. There is also relief for some federal Central Valley Project users.
A new survey finds Californians are split over the cause of the state's drought.
Hundreds of waterfalls are cascading throughout Yosemite National Park, but they may not last too much longer.
California and federal agencies have released a plan about how they’ll operate the state and federal water projects during the drought. The plan does not change water allocations.
