报告简介：

Many consider the launch of GRACE as marking a landmark in satellite geodetic observations of critical climate processes. In reality, satellite geodesy has been advancing our understanding of these processes since at least the launch of Seasat in 1978, a mission that infamously only lasted 100 days but which transformed our ability to observe ocean circulation, mesoscale eddies and began the record of radar altimeter measurements over the ice sheets. Another milestone was the launch of ERS-1 in 1991, heralding the start of routine observations of millimetric-level surface displacements via SAR interferometry (InSAR), and unprecedented accuracy elevation measurements of the oceans and ice sheets. Here, I consider how this trinity of technological advances—satellite gravimetry, radar and laser altimetry and InSAR-- have revolutionised our understanding of mass movement at the surface of the Earth, focusing on recent insights we have made on data-driven solutions for Glacial Isostatic Adjustment, tackling the Terrestrial Water Storage budget Grand Challenge, global water stress trends, closing the Sea Level Budget at the basin scale and global ice mass trends. I will conclude by considering the future of satellite geodesy as a tool for climate science in the context of recent and planned missions such as NISAR, SWOT, Harmony and MAGIC.

报告人简介：

Jonathan Bamber is professor of glaciology and Earth Observation, University of Bristol and Senior Research Fellow at Technical University Munich in the Dept of Aerospace and Geodesy. He is former Director of the Bristol Glaciology Centre and former President of the European Geosciences Union.

He has a degree in physics and a PhD in geophysics. He has ~40 years experience in the analysis of airborne & satellite data sets from the polar regions, specialising in combining these data with models of the Earth system. He is an expert on the ice sheets covering Antarctica and Greenland and their contribution to sea level. He has also worked extensively in the general field of geodesy, covering mapping of the surface topography of the Earth, sea level variations in time and space and measuring mass exchange between the land and oceans due to melting of land ice and the hydrological cycle and solid Earth deformation. He is currently a member of ESA’s most high level advisory body the Advisory Committee for Earth Observation and a member of the European Space Science Committee and the EU Science Advisory Board for their ambitious ~900M euro project to develop a Digital Twin for the Earth: DestinE.
