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.
Caltrans is worried about the possibility of dead trees falling onto some California highways. The agency has already removed 107,000 trees. Now the agency is getting ready to remove another 54,000 trees, including some on private land.
Sacramento city council voted in favor of a proposal that makes some drought watering restrictions permanent.
Tuesday marks the start of a shortened commercial salmon fishing season in the waters off San Francisco. A smaller salmon population is one effect of the drought that could persist for years.
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.
