报告摘要：The Earth climate system has experienced significant changes over the past several decades driven by global warming. Global climate change is characterized by changing long-term variability in different components of the Earth system, including the atmosphere, ocean, hydrosphere, and cryosphere. The first part of this presentation will give an overall picture of global climate change using data from state-of-the-art Earth observation techniques. Since the launch of the Gravity Recovery and Climate Experiment (GRACE) in 2002, satellite gravimetry has provided a revolutionary means for measuring large-scale mass variations in the Earth system with unprecedented accuracy. Time-variable gravity measurements from GRACE and GRACE Follow-On (GFO, launched in 2018) have been successfully used to study water mass movement and redistribution in different components of the climate system, and greatly improved our understanding of climate change. The second part will introduce GRACE/GFO applications using examples in different areas of climate change studies.
