Measuring Earth's Surface Mass and Water Changes

GRACE Follow-On (GRACE-FO) is continuing GRACE’s legacy of tracking Earth’s water movement across the planet. Monitoring changes in ice sheets and glaciers, underground water storage, the amount of water in large lakes and rivers, and changes in sea level provides a unique view of Earth’s climate and has far-reaching benefits for its people.
