In the first postdoctoral research of the French National Institute for Ocean Development, Chen Ge showed the spirit of seeking truth and being pragmatic and being brave in questioning. Just half a year after he arrived in France, he questioned the calculation method of "frequency aliasing of ocean tides observed by satellite altimeter" proposed by Professor Dudley Chelton, an authoritative expert in the field of international satellite altimeter and a well-known American scholar who published many groundbreaking papers in Science and Nature, and pointed out his mistakes. Professor Chelton later corrected his mistake, and especially thanked Chen Ge in the American Journal of Geophysical Research. Chen Ge's scientific and realistic, rigorous and meticulous, sensitive and studious, and not superstitious about authority left a deep impression on his French counterparts. Everyone began to look at this young man from China with new eyes. When Chen Ge left France, Professor Cristina Ka saros, director of the Department of Space Oceanography of the French National Institute for Ocean Development, said to Chen Ge in front of many people: "There are also international experts in the field of satellite altimetry in China, and you are one of them!"
Chen Ge's excellent work ability and solid work style attracted the attention and appreciation of Academician Xu Guanhua, Minister of Science and Technology, and became his first postdoctoral fellow. During the second postdoctoral period, Chen Ge made one achievement after another. During the period of 1999-2000, 4 SCI papers were published in international journals. During this period, the total number of SCI papers of the Institute 100 was less than 20, and Chen Ge once again caused quite a response. In 2000, when Chen Ge left the postdoctoral program of Chinese Academy of Sciences, Xu Guanhua personally attended and presided over his lecture. Xu Guanhua spoke highly of Chen Ge's research achievements and praised him as "an outstanding young talent in the field of marine remote sensing in China". Dr. Li Lianfu, the chief scientist of the International Satellite Altimeter, also wrote in the letter: "Chen Ge is one of the best young professors in the international marine field, especially in the field of marine remote sensing, and will become a new generation of internationally competitive academic leaders."
With this fighting spirit, Chen has presided over eight key scientific research tasks, including the National 863 Program, the National Fund for Distinguished Young Scholars and the Sino-French inter-governmental international cooperation project, focusing on ocean remote sensing, especially the physical mechanism, inversion theory, information processing and ocean application of satellite altimeter, which not only opened up new research directions for the school, such as marine geographic information system and virtual marine geographic environment. Moreover, a series of original research achievements have been made in the field of satellite ocean atmospheric remote sensing: a remote sensing method using satellite altimeter to retrieve global ocean rainfall has been established for the first time in the world, which has opened up a new application field for satellite altimeter; The sampling characteristics of satellite altimeter are theoretically analyzed and simulated from the angle of energy for the first time, and the influence of frequency confusion on the recovery of altimeter ocean signal and the methods to eliminate these influences are systematically expounded, which has important reference value for the altimeter satellite planned to be launched in China. The key technology of altimeter sea surface wind speed inversion has been effectively improved, and the accuracy has been improved by 10%. Using satellite remote sensing observation, the meridional oscillation law of Pacific windless area during strong El Ni? o event was found, which provided new clues for exploring the causes and mechanisms of El Ni? o phenomenon. In addition, he also successfully observed and revealed for the first time in the world three "surge pools" in the equatorial Pacific Ocean, the Atlantic Ocean and the Indian Ocean and their structures strengthened eastward by satellite scatterometer and altimeter. His research work is at the forefront of the world, and some of his achievements are in the leading position at home and abroad. On this basis, he published more than 60 academic papers, of which 20 representative papers were included in the American Science Citation Index SCI. After their publication, these papers were not only requested by scholars from dozens of countries, such as Britain, the United States and France, but also cited by more than 10 internationally renowned SCI publications and several international authoritative academic monographs. At the same time, his achievements in the change of global sea surface wind field have also been selected for the cover of Chinese and English editions of Science Bulletin, which is the first time in the field of marine remote sensing research.
With the deepening of scientific research and the continuous improvement of international academic status, since 1995, Chen Ge has been invited to serve as the chairman of the "satellite altimeter" or "ocean remote sensing" branch of the newly held international academic conference in France, Canada, India, and became one of the youngest branch chairmen of this major. He was invited to give a special report at the high-level seminar organized by the United Nations Environment Programme, which won honor for the country.
During the interview, we noticed that there was a slightly shabby notebook on Chen Ge's left hand side, on which his daily schedule and work plan were written. Chen Ge said that he is a man with strong planning and regularity. As long as what is written into the plan, it must be completed with good quality and quantity.
"Teacher Chen is not only very planned, but also very tolerant of loneliness. In order to overcome an academic problem, he often does not answer the phone, does not see guests, and sometimes even completely closes himself up. " His students said so. We asked Chen Ge himself for verification. Chen Ge smiled: "A scholar must have a scientific and rigorous spirit of seeking truth, a persistent loneliness and a peaceful mind that is indifferent to fame and fortune." Under the subtle influence of Chen Ge, all his graduate students go to the laboratory early every day and don't go back to the dormitory to rest until late.
