On December 29, State Key Laboratory of Geodesy and Earth’s Dynamics (SKLGED) of Institute of Geodesy and Geophysics(IGG) held a symposium on satellite gravity/altimetry monitoring of lakes and other land surface quality changes. Researchers Yan Haoming, associate Researchers Zhang Zizhan and Feng Wei presided over the report. Wang Yong and Ni Sidao, deputy director of the IGG, and some researchers attended the meeting. The meeting invited experts and postgraduates from Wuhan University, Nanjing University, Huazhong University of Science and Technology and Shanghai Astronomical Observatory, Chinese Academy of Sciences to report on the progress and achievements in related fields.

Associate Professor Zhong Bo from Wuhan University introduced the GRACE mascon solution method and its application in water monitoring of the South American basin. Associate Professor Xu Yuyue from Nanjing University introduced the progress of satellite remote sensing monitoring of the dynamic monitoring of large lakes in the middle and lower reaches of the Yangtze River. Associate researcher Li Jin from Shanghai Astronomical Observatory, Chinese Academy of Sciences reported the impact of ellipsoid correction on the inversion of global land surface quality changes. Dr. Ni Shengnan from Huazhong University of Science and Technology reported on the research progress in the study of the lake water reserves changes in Walter Lake and Qinghai-Tibet Plateau using Multi-source Satellite data. Associate Professor Feng Wei and Zhan Jingang from IGG reported on the use of satellite geodesy to study groundwater, glacial changes and their relevance to climate change. Shen Yingchun, Li Zhen, and Li Yan, graduate students from IGG reported their progress on the inversion of land water reserves of by GPS displacement, river sediment deposition, and Antarctic ice exploration respectively.

The participating young scholars conducted detailed and in-depth discussions around the contents of the relevant report, and the atmosphere was very active. With the development of satellite gravity, satellite altimetry geodesy and remote sensing observation technology, it has been more and more widely used in surface fluid and global change monitoring. The seminar aims to provide opportunities for communication between satellite geodetic and remote sensing in the field of thematic research.
