| Abstract |
GRACE is an international cooperative US-German dual-minisatellite SST (Satellite-to-Satellite Tracking) geodetic mission with the overall objective to obtain long-term data with unprecedented accuracy for global (high-resolution) models of the mean and the time-variable components of the Earth's gravity field (a new model of the Earth's gravity field every 30 days for five years). GRACE is also part of NASA's ESSP (Earth System Science Pathfinder) program. Some science objectives are:
• To enable a better understanding of ocean surface currents and ocean heat transport
• To measure changes in the sea-floor pressure
• To study ocean mass changes
• To measure the mass balance of ice sheets and glaciers
• To monitor changes in the storage of water and snow on the continents
