NASA’s Gravity and Climate Experiment (GRACE) is a mission to track the impact of climate change on the planet’s vast stores of freshwater, saltwater, and ice. A pair of satellites, GRACE effectively “weighs” Earth’s shifting water resources month by month to detect where water is accumulating or drying up.
With these resources, students can explore real data to see for themselves how Earth's water is changing.
These teaching case materials explore how scientists can use satellite data to track the loss of ice on Earth.
Data from the GRACE satellites allow scientists to see how fresh water is being redistributed across the continents over time.
Pick a location (Greenland or Antarctica), and timeframe between 2003-2014, and see how water stores have changed over time.
