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.
A wealth of weather and climate data and the jobs of the scientists who analyze it may be at risk under President Trump’s budget proposal.
The Central Sierra Nevada snowpack this year is larger than the previous four years combined, according to new data from NASA.
It is now the wettest season on record in Northern California, where most of the state gets its water supply.
Some farmers in the San Joaquin Valley will finally get a full supply of water.
California Governor Jerry Brown ended the drought state of emergency in most of California Friday. Water reporting requirements and prohibitions on wasteful practices are still in place.
