This visualization of a gravity model was created with data from NASA's Gravity Recovery and Climate Experiment and shows variations in the gravity field across the Asia and Australia.
This visualization of a gravity model was created with data from NASA's Gravity Recovery and Climate Experiment and shows variations in the gravity field across the Americas.
This image is from data taken by NASA's Gravity Recovery and Climate Experiment showing the Amazon basin in South America. The amount of water stored in the Amazon basin varies from month to month.

NASA's GRACE mission has become a key source of knowledge about global ice mass changes. Studies of Greenland using GRACE and other data indicate that between 2000 and 2008 the Greenland ice sheet lost as much as 1,500 gigatons of mass.
This frame from an animation based on data from NASA's Grace satellite shows dramatic changes in Greenland's ice mass from 2003 through 2011 revealing how much ice has been lost and gained each year.
This visualization of a gravity model was created with data from NASA's Gravity Recovery and Climate Experiment (GRACE) and shows variations in Earths gravity field.
This visualization of a gravity model was created with data from NASAs Gravity Recovery and Climate Experiment and shows variations in the gravity field across Africa and Europe.
