The first symposium on satellite gravity and hydrology was held in Beijing between the 25th and 26th of June. Co-sponsored by CNU, Tsinghua University and Institute of Geodesy and Geophysics, Chinese Academy of Sciences, the event was hosted by Beijing Lab for Safe Water Resources of CNU. It was an academic event for cross research in satellite gravity and hydrology in China and overseas.


147 scholars from 58 institutions were present at the event in which 28 reports were made. Among those who were present at the symposium were Dr. Bridget R. Scanlon from University of Texas at Austin, member of American NAE, Dr. Laurent Longuevergne from University of Rennes, Dr. Pat J.-F. Yeh from National University of Singapore, Researcher Ni Sidao, Deputy Dean of Institute of Geodesy and Geophysics, Chinese Academy of Sciences, national prominent researcher and Changjiang Scholar, Distinguished Professor Hong Yang from Tsinghua University, a distinguished professor of the “1000 Talent Program”, and scholars from Jiling University, Tsinghua University, Wuhan Institute of Geodesy and Geophysics, Chinese Academy of Sciences and business departments from the Ministry of Water Resources.


President Gong Huili made a speech at the forum. Speeches were also made by Prof. Hong Yang, and Researcher Zhong Min from Institute of Geodesy and Geophysics, Chinese Academy of Sciences, Dr. Bridget R. Scanlon and Dr. Laurent Longuevergne. Specialists and scholars from different domains made their reports on data processing of satellite gravity, inversion of water resources, climate change and human activities.


The gravity satellite, with its vision, has provided different sources of data and it is the only remote means to directly observe the change of underground water. Especially true is the satellite of gravity recovery and climate experiment (GRACE), which has, since its launching in 2002, made very important discoveries in changes of underground water, glaciers, and sea levels. And it has become a heat point and pioneer in the research of hydrology. In order to enact the coordinated development of Beijing, Tianjin and Hebei, CNU has, for the first time, used GRACE satellite to explore the differences of changes in underground water reserves in the plains of North China. With the help of GRACE satellite, it has been proved for the first time that deep layer underground water has been over extracted. This unique means has provided important bases for the management of regional underground water resources and control of ground setting. The research was published in Geophysical Research Letters (IF="4.212)," one of the top international journals.


The second forum will be held at Tsinghua University next year.
