地球与行星物理学术报告通知（202627期）- 陈剑利

报告人简介：

Prof. Jianli Chen is a Chair Professor of Space Geodesy and Earth Sciences in the Department of Land Surveying and Geospatial Science, The Hong Kong Polytechnic University. Prior to moving to Hong Kong, he had spent 28 years of his academic career at the University of Texas at Austin. Prof. Jianli Chen is a world-renowned expert in space geodesy and its applications in Earth sciences. He has been working on topics related to global climate change and geophysical applications of space geodetic techniques, including satellite gravimetry, satellite altimetry, and other geodetic measurements for over 30 years. He has been extensively involved in data processing, results validation, and geophysical interpretation of the Gravity Recovery and Climate Experiment (GRACE) satellite gravimetry mission and is a leading science team member of both the GRACE and GRACE Follow-On missions. He is a fellow of the American Geophysical Union (AGU) and International Association of Geodesy (IAG) and has severed as the chair of the IERS Special Bureau for Hydrology since 2004. A crowning distinction of his decorative career was the 2005 US Presidential Early Career Awards for Scientists and Engineers (PECASE), the highest honor bestowed by the United States government on early career scientists and engineers (he was the first and so-far the only PECASE awardee in the geodesy field). He has published over 190 refereed journal publications, with over 60 as lead author.

报告内容摘要：

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 (GRACE-FO, launched in 2018) have been successfully used to study water mass movement and redistribution in different components of the Earth system, and greatly improved our understanding of global climate change. This presentation will give an overall introduction of GRACE/GRACE-FO satellite gravimetry, data processing methods, and applications using examples in different areas of climate change studies.
