On October 20 and 21, 2016, Research Fellow GU Xingfa, Deputy Director of RADI, and Research Fellow Shao Yun, a project leader of “Construction and Demonstration of Precise Emergency Service System through Synergy Observation of Spaceborne, Airborne, and Ground Remote Sensing” attended the Second China-U.S. Civil Space Dialogue in Washington, D.C., at the invitation of the U.S. Department of State. The meeting was co-chaired by TIAN Yulong, Chief Engineer of China National Space Administration (CNSA), and Jonathan Margolis, Deputy Assistant Secretary of the U.S. Department of State. Forty-five were present at the meeting, including Charles Bolden, Administrator of the National Aeronautics and Space Administration (NASA), and Ken Hodgkins, Director of the Office of Space and Advanced Technology in the U.S. Department of State. Both sides held in-depth discussions on the application of civil space and satellite technology.
GU gave a speech titled “Research on Space Technology Applications and Global Climate Change”. He stressed that it is urgent to define higher requirements for Earth observation in response to climate change and global changes in the implementation of the 2030 Agenda for Sustainable Development. The United States and China, two spacefaring powers and respectively the number one and two economies in the world, should take on important responsibilities, historically and internationally. After introducing China's Earth observation system and its applications, GU pointed out that China has developed a satellite observation system covering atmosphere, land, ocean and geophysics, and produced achievements in global land cover and ecological monitoring to provide important spaceborne data for research on global change. He also discussed China’s efforts in cooperation with more than 60 countries including the United States and those in Europe, Africa and Asia in the fields of satellite development and data application and its active participation in GEOSS-related activities, as well as its substantial international science programs. He also made proposals concerning further cooperation between China and the United States.
SHAO Yun gave a speech titled “Satellite Application for Global Geological Disaster Monitoring”, which focused on the status quo and trends in satellite applications for geological disaster monitoring, China's important contributions in this regard, and relevant satellite programs. Since 2008, China has provided some 20 worldwide natural disaster requests with more than 140 scenes from China-made satellites, including responses to three requests from the United States. China is developing its seismo-electromagnetic satellite designed to acquire observation data concerning plasma, electromagnetic fields, and energetic particles; to identify the abnormal state of electromagnetism, ionosphere and energetic particles before the occurrence of violent earthquakes; and to explore methods for short-term earthquake forecasts. With advanced performance and varied working patterns, GF-3, a synthetic aperture radar (SAR) satellite independently developed by China, can generate 1-meter resolution radar images and 8-meter complete-polarization radar images. Research Fellow Shao Yun introduced the result of monitoring landslides in Guizhou Province with GF-3, which demonstrates strong abilities to detect static information and dynamic change mechanisms of landslides, which will play a great role in geological disaster monitoring. She also briefed the delegation on the application of co-seismic deformation monitoring and differential interferometry synthetic aperture radar (D-InSAR) in major geological disasters including the Wenchuan and Yushu earthquakes. Due to less dependence on correlation than that of InSAR, D-InSAR monitors multi-scale changes of crustal deformation more precisely. In addition, Ms. Shao made suggestions for cooperation between China and the United States in geological disaster research by taking into account the status quo of satellite applications in global geological disaster monitoring.
Jonathan Margolis and Timothy Newman, leader of the Land Remote Sensing program of the United States Geological Survey (USGS), highly appreciated China's notable contributions in global geological disaster monitoring, actively responded to China’s proposals and expects further cooperation with RADI by taking opportunities to develop key projects.
