GRACE

Tracking Water From Space

Data from the GRACE satellites allow scientists to see how fresh water is being redistributed across the continents over time.

GRACE Measures Changes in Total Freshwater Storage

 

2003
2009

The GRACE data visualization shows changes in total freshwater storage across the landscape for the period January 2003 to March 2009, relative to the average amount of water at that location during this period. The blue colors show regions that are wetter than the average and the red colors show regions that are dryer.
