Mountain snow – a bank account for water across the western U.S. – has turned up insufficient funds this year. The Sierra Nevada snowpack melted nearly a month earlier than usual, leaving reservoirs without their usual inflow of freshwater.
In the face of severe west-U.S. drought, NASA has launched a new page highlighting its eyes on the drought, which are helping track and monitor the ongoing drought, predict how much water will be available, and improve how we use the water we have.
Four years after California emerged from a severe multi-year drought, the state’s precipitation and lake levels are among their worst since the 1970s. The deepening drought is seen in satellite images of the state’s two largest reservoirs.
For the second year in a row, drought has overtaken much of the U.S. from the Rocky Mountains to the Pacific Coast. Our Crop-CASMA soil moisture data portal, jointly developed with the U.S. Department of Agriculture, reflects the dry times.
The 2021 SnowEx field campaign, which is helping determine how much water winter snowpack holds, has come to a close. Teams took snow measurements at six sites across the western U.S., on the ground and with drones and airplanes flying overhead.
The very ground upon which Corcoran lies has dipped nearly 12 feet in 14 years as a result of pumping of underground water for irrigation. Scientists can track the subsidence in the region using radar and satellite technology.
For years, scientists looked for ways to measure large-scale changes in Earth’s water cycle. Satellites measuring the gravity of water delivered. From 2003 to 2019, land evapotranspiration increased by 10%, one sign that our water cycle is ramping up.
After one of the warmest, driest springs on record, most of the American west is in extensive drought. Amid acute water shortages in northern and central California, a drought emergency has been expanded to a large swath of the state.
A new study finds that covering thousands of miles of California’s canals with solar panels could help the state meet its ambitious goals to reduce greenhouse emissions as well as improve irrigation management.
Researchers have found a new way to measure the depth of some of the most isolated, shallow lakes, using NASA's ICESat-2 satellite. Knowing the shapes of lake beds in dry regions enables us to better estimate the amount of water stored in these basins.
Harmful algal blooms are often hard to predict. NASA's Earth-observing satellites are uniquely poised to help spot them, and track the many ways that different parts of the Earth's system are connected.
From big to small...we’re all connected. In honor of Earth Day this week, NASA is hosting an Earth Day Virtual Event and releasing a range of activities, live talks, games, videos and great downloadable posters and books.
The Cyanobacteria Assessment Network (CyAN) - a joint EPA, NASA, NOAA and USGS project - uses satellites to monitor harmful algal blooms in over 2,000 of the largest U.S. lakes. Since its launch, CyAN has saved millions of dollars in monitoring and health costs.
In 2020, there were 22 billion-dollar U.S. climate disasters - floods, storms, droughts, heatwaves. One third of U.S. homes are at high risk from natural disaster, with many homeowners bearing the brunt of costly repairs.
A comprehensive new review calls for urgent climate action to secure nutrition around the world. Climate change will have a major impact on global food production and human health without collaboration betwen consumers, food industries, policy makers and government.
Earth data are becoming more widely valued. For the first time, satellite data have been included in the World Health Organization’s guide on monitoring harmful algal blooms worldwide. The update draws directly from the Cyanobacteria Assessment Network, a multi-agency water project involving NASA.
In the face of a global pandemic, 2020 underscored the need for data to drive decision making. Improving the way we manage water is as critical as ever. WWAO’s Annual Report, now available, summarizes how we endeavored to move the needle in 2020.
NASA’s Harvest program and soil analytics company CropX have announced a new partnership. The alliance will provide farmers and industry experts with insights that help improve farming sustainability by conserving resources and improving crop yields.
NISAR, an SUV-sized Earth satellite that will feature the largest reflector antenna ever launched by NASA, is taking shape in the clean room at NASA's Jet Propulsion Laboratory. Its mission is to track disasters as well as the effects of climate change.
WWAO's new soil moisture data portal - Crop-CASMA - is live. Crop-CASMA, which provides high-resolution, field-scale soil wetness from NASA satellites in an easy-to-use format, is a collaboration between NASA, the U.S. Department of Agriculture and George Mason University.
Using NASA's Ice, Cloud and land Elevation Satellite 2 (ICESat-2), scientists have shown humans are having a much bigger impact on surface storage variability than previously thought, with over half of the planet's variability happening in managed reservoirs.
California's annual rainy season now begins a month later than it did just 60 years ago, shifting from November to December. The results are consistent with climate models that predict drier autumns for California in a warming climate.
WWAO is launching new water projects in the U.S. Columbia River Basin. As part of this effort, we’re looking for information on activities using NASA data or technology that could address key water issues in the region.
Rivers are among the most degraded ecosystems on Earth. The first map of river color from Landsat surface-reflectance data shows one third of U.S. rivers have changed color significantly over the last 35 years.
A new agreement between the U.S. Department of Agriculture and NASA will strengthen agricultural and Earth science research. WWAO’s collaboration with the USDA on its High-Resolution Soil Moisture Project fits into this larger partnership.
Farmers rely on the Landsat satellite to make decisions about crops, with far-reaching implications that can impact what we see on our dinner plate. In this curious video, Landsat's view of crops from space can be heard in the form of music.
A serious drought has flared up across half of the United States, with about a third of the country suffering from extreme or exceptional drought. This familiar story has been playing out for the past two decades.
Launched three weeks ago, the Sentinel-6 Michael Freilich satellite has returned its first data and is surpassing expectations. The NASA-U.S.-European satellite will measure sea-level rise with unprecedented accuracy.
