GRACE-FO Instruments

The GRACE-FO satellites are nearly identical. The Microwave Interferometer (MWI) will measure the minute variations in distance between the spacecraft.

The GRACE-FO satellites are nearly identical. The Microwave Interferometer (MWI) will measure the minute variations in distance between the spacecraft. Accelerometers will record forces on the spacecraft other than gravity, such as atmospheric drag and solar radiation. GPS will keep track of the spacecraft position relative to Earth's surface.

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.

In a recent study, scientists found that a previously unmeasured source – water percolating through soil and fractured rock below California’s Sierra Nevada mountains – delivers an average of 4 million acre feet (5 cubic kilometers) of water to the state’s Central Valley each year. This underground source accounts for about 10% of all the water that enters this highly productive farmland each year from every source (including river inflows and precipitation).
