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.
Record dry January expected in many Northern and Central California cities as drought drops reservoir levels.
The California Department of Water Resources says the state’s snowpack is “dismally meager.” A lack of snow in the Sierra is keeping rivers low and drying up some reservoirs.
The City of Roseville is yanking grass and replacing it with drought-resistant landscaping to conserve water. Roseville also offers homeowners a 'Cash For Grass' rebate program.
The City of Sacramento says water customers in 2014 "cut water use to the lowest level per person per day in 100 years."
Salmon rely on cool water temperatures and aquatic plants to survive. So California’s drought has hit them particularly hard. But UC Davis researchers have found one area where the fish are flourishing.
