| Session Description | The Gravity Recovery and Climate Experiment (GRACE) mission has been providing a precise survey of the Earth’s time-variable gravity field since it was launched in 2002, with unprecedented temporal and spatial sampling. GRACE time-variable gravity fields provide a means of measuring temporal and spatial variations of mass redistribution within the Earth system. The GRACE mission has launched a new era in studying a series of geophysical problems ranging from deep Earth structure to tracking mass redistribution on and near the surface of the Earth. GRACE has greatly improved understanding of mass redistribution in various compartments of the Earth climate system, including the atmosphere, ocean, terrestrial water, and cryosphere. Aside from the successful applications of GRACE satellite gravity measurements in monitoring and measuring mass changes in the climate system, there are still major challenges in validating GRACE measurements and improving data processing methods that can better recover climate change signal from GRACE measurements. This session solicits contributions ranging from validations and uncertainty assessments of GRACE measurements, improved data calibration and processing methods, to geophysical applications of GRACE data in improving the understanding of the Earth geodynamic change and global mass transport and redistribution in the climate system. |
