Groundwater Drought Indicator

While the GRACE mission was active, scientists at NASA’s Goddard Space Flight Center generated groundwater and soil moisture drought indicators like this every week from GRACE data on terrestrial water storage and other observations, using a numerical model of land surface water and energy processes.

This map from September 2015 shows deep drought in California, Nevada and Texas. While the GRACE mission was active, scientists at NASA’s Goddard Space Flight Center generated groundwater and soil moisture drought indicators like this every week from GRACE data on terrestrial water storage and other observations, using a numerical model of land surface water and energy processes. They will resume producing maps when GRACE-FO data are available.

The GRACE Intermediate Field 48 (GIF48 from UT-CSR) field model is an improved mean gravity field that combines GRACE observations and terrestrial gravity information The terrestrial gravity information was taken from the DTU10 global gravity field. Shown here are the so-called free air gravity deviations from an ideal ellipsoidal Earth model, in units of milli-gal. Areas colored yellow, orange, or red are areas where the actual gravity field is larger than the featureless-Earth model predicts, while the progressively darker shades of blue indicate places where the gravity field is less.

GRACE Follow-On (GRACE-FO) continues the legacy of GRACE, tracking Earth’s water movement and surface mass changes across the planet. Monitoring changes in ice sheets and glaciers, near-surface and underground water storage, the amount of water in large lakes and rivers, as well as changes in sea level and ocean currents provides an integrated global view of how Earth’s water cycle and energy balance are evolving.

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).
