GRACE data have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected sea level rise. read this article

To gain a continent-scale overview of the drought in Brazil, Augusto Getirana of NASA’s Goddard Space Flight Center turned to data from the Gravity Recovery and Climate Experiment (GRACE). Because droughts arise from planet-scale shifts in climate, Getirana’s study suggests that gravitational data could help tie those shifts to local shifts in ground and surface water. read this article

National Geographic offers a look at NASA's Earth-observing missions, including GRACE. Satellite and airborne sensors won't cure the Earth. But they promise the clearest picture yet of its various ailments. read this article

Intensive research, aided by NASA observations and analysis, points to an unavoidable future sea level rise of several feet. The question is, how quickly will it happen? read this article

July 30, 2015
A new NASA study has concluded California accumulated a debt of about 20 inches of precipitation between 2012 and 2015 -- the average amount expected to fall in the state in a single year. The deficit was driven primarily by a lack of air currents moving inland from the Pacific Ocean that are rich in water vapor. read this article

From the Arabian Peninsula to northern India to California’s Central Valley, nearly a third of the world’s 37 largest aquifers are being drained faster than they are being replenished, according to a recent study. read this article

June 18, 2015
Jay Famiglietti, senior water scientist at JPL, talks with Rachel Maddow about research using satellites to detect underground water around the world and finding startling deficiencies in the global water supply. read this article

June 18, 2015
The world’s largest underground aquifers – a source of fresh water for hundreds of millions of people — are being depleted at alarming rates, according to new GRACE data that provide the most detailed picture yet of vital water reserves hidden under the Earth’s surface. read this article

June 17, 2015
New research reveals that humans are rapidly draining water from about a third of the world’s biggest underground basins, or aquifers, more rapidly than they can naturally be replenished. read this article

June 16, 2015
About one third of Earth's largest groundwater basins are being rapidly depleted by human consumption, despite having little accurate data about how much water remains in them, according to two new studies led by the University of California, Irvine, using data from NASA's GRACE satellites read this article

GRACE’s data show that aquifers, at current rates of withdrawal, will be gone within decades. read this article

Thanks to an agreement with JPL for the new U.S.-German GRACE Follow-On mission, the Center for Space Research at UT Austin will have a key role in shaping what space geodesy (the science of accurately measuring variations in the Earth’s land, ice and mass) will look like over the next 10 to 15 years. CSR Director Byron Tapley said the mission will allow them to continue the measurements of water and mass movement that GRACE has been making during the last decade. read this article

Michael Watkins, who worked at NASA's Jet Propulsion Laboratory for 22 years and now oversees JPL's Science Division, begins his new job at UT this July. read this article

April 2, 2015
Jay Famiglietti, a senior water scientist at NASA's Jet Propulsion Laboratory, published an op-ed in the L.A. Times. Online the headline read: "California has about one year of water left. Will you ration now?" He didn't write or intend that that headline. read this article

GRACE data showed that since 2011, the Sacramento and San Joaquin river basins dropped in volume by four trillion gallons of water each year. read this article

JPL’s Gravity Recovery and Climate Experiment, twin Earth orbiters that are tracking groundwater loss, were featured in a 60 Minutes segment Sunday, Nov. 16. read this article

November 7, 2014
JPL’s senior water scientist, Jay Famiglietti, tells us that NASA’s GRACE Satellites (Gravity Recovery And Climate Experiment) which launched in 2002, surveys the Earth’s fresh water from space. The satellite shows how much water is available in underground reservoirs, and his team tracks how these water reserves are changing. Before GRACE, there was no other way to measure how much water was underground. GRACE Follow-On will launch in 2017 to continue the imporatant work of GRACE. read this article

GRACE data shows that water in the world’s largest aquifers is being pumped out at greater rates than can be replenished naturally. read this article

July 28, 2014
A new study using GRACE data finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. read this article

Every year, river flooding takes a heavy toll of lives and property damage in the United States. A new study has found that the potential of a river basin to flood can be assessed months in advance of flood season by using data from NASA's Gravity Recovery and Climate Experiment (GRACE) twin satellites. The new finding could eventually lead to longer lead times for flood warnings. read this article

July 7, 2014
Researchers at the University of California at Irvine drew up a map of the Mississippi River basin combining knowledge about land use and data from a NASA gravity-monitoring satellite called GRACE. Minute increases in the gravitational pull pointed to higher "wetness" of the land, they found. read this article

Advisory from UC Center for Hydrologic Modeling finds statewide averages of snow, surface water and soil moisture near 10-year lows. Threat of multi-year epoch of unsustainable groundwater depletion imminent if drought continues. read this article

January 27, 2014
Scientists at NASA’s Goddard Space Flight Center generate groundwater and soil moisture drought indicators each week. They are based on terrestrial water storage observations derived from GRACE satellite data and integrated with other observations, using a sophisticated numerical model of land surface water and energy processes. read this article
