Researchers are using powerful supercomputers at TACC to process data from Gravity Recovery and Climate Experiment (GRACE). “Intended to last just five years in orbit for a limited, experimental mission to measure small changes in the Earth’s gravitational fields, GRACE operated for more than 15 years and provided unprecedented insight into our global water resources, from more accurate measurements of polar ice loss to a better view of the ocean currents, and the rise in global sea levels.”
