On the morning of November 15, Zhang peng, deputy director of the national center for satellite meteorology and director of the ground application system of global carbon dioxide monitoring satellite engineering, delivered an academic report entitled “observation operators and atmospheric radiation transmission of information assimilation of fengyun satellite” in conference room 310 of the meteorological building at the invitation of the department of science and technology and the school of atmospheric science. College teachers and students took an active part in atmospheric science.

Dr.Zhang first introduced the current status, strengths and weaknesses, applications and progress of the satellite of China. He gave a detailed explanation of atmospheric radiation transmission theory, observational operators and applications of fengyun satellites, and conducted a series of discussions on satellite data assimilation and numerical simulation. He put forward some important conclusions that numerical prediction model is closely connected with observation system, data quality is the premise and foundation of the satellite data assimilation and so on. This is of great significance to the development of fengyun satellite and the application of satellite data.

After the lecture, the experts exchanged and discussed with the teachers and students present. This exchange activity created a good atmosphere of academic exchange, which further deepened students’ understanding of numerical simulation and assimilation of satellite data, and promoted students’ enthusiasm for learning.

Expert introduction: Zhang peng, doctor, researcher, deputy director of national satellite meteorology center, general director of ground application system of fengyun-3 pole orbiting meteorological satellite engineering, general director of ground application system of global carbon dioxide monitoring scientific experiment satellite engineering. He has published over 100 academic papers in core journals at home and abroad, including 41 SCI papers, which have been cited for over 900 times. He has won 4 provincial and ministerial awards.
