Measuring Earth's Gravity from Space Poster

An international team of scientists using observations from NASA-German satellites found evidence that Earth’s total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since.

GRACE and GRACE-FO observations are now addressing the crucial need for sustainable groundwater management practices to ensure water resiliency amidst ongoing climate challenges in California.

The Gravity Recovery and Climate Experiment-Continuity mission will extend a decades-long record of following shifting water masses using gravity measurements.

This immersive experience leverages satellite data to illustrate how climate change is impacting Earth’s water cycle.

Early data shows the greatest net gain of water over the winter in nearly 22 years, but the state’s groundwater levels still suffer from the effects of years of drought.

Scientists have predicted that droughts and floods will become more frequent and severe as our planet warms and climate changes, but detecting this on regional and continental scales has proven difficult. Now a new NASA-led study confirms that major droughts and pluvials – periods of excessive precipitation and water storage on land – have indeed been occurring more often.
