General situation of disciplines
Atmospheric physics is a science that studies the process, phenomenon and evolution of atmospheric physics, as well as the principles and methods of detecting the atmosphere. It is the basic theoretical part of atmospheric science. The atmospheric phenomena it studies include atmospheric sound image, light image, electric image, radiation process, cloud and precipitation process, boundary layer atmospheric process and stratosphere and mesosphere atmospheric phenomena.
Atmospheric environment is a science that studies the physical processes of transportation, diffusion and deposition of pollutants and trace components in the atmosphere and the chemical transformation process in the atmosphere, including the formation and evolution of the earth's atmosphere, the circulation of trace components, stratospheric atmospheric photochemistry, tropospheric atmospheric photochemistry, aerosol formation and evolution and its impact on the atmosphere, precipitation chemistry, global changes of geosphere-biosphere interaction, etc.
The major of atmospheric physics and atmospheric environment includes the following sub-disciplines: atmospheric radiation, atmospheric boundary layer meteorology, atmospheric acoustic photoelectric physics, atmospheric exploration and atmospheric remote sensing (radar meteorology, satellite meteorology, radio meteorology), cloud and rain physics, stratosphere and mesosphere physics, atmospheric chemistry and air pollution meteorology. These disciplines constitute the foundation of atmospheric science and have unique applications in various fields of national economy and national defense.
The discipline of atmospheric physics and atmospheric environment is based on physics, mathematics, chemistry, fluid mechanics, radio electronics and computer science and technology, taking atmospheric phenomena and processes as the research object and intersecting with meteorological branches; Closely combined with space physics, biogeochemistry, radio communication and other disciplines, it supports and expands the development and application of contemporary high technology and continuously expands its own research field.

At present, global environmental change is a challenging and complex scientific problem, and its research objects include lithosphere, atmosphere, hydrosphere, cryosphere and biosphere of the earth system. The research content covers various phenomena, processes and interactions between various parts of the earth system. In addition, there are complex interactions and feedbacks between human activities and global environmental changes. Global environmental change mainly involves physical, chemical and biological processes. The integrated analysis and coupling simulation of these three processes have just started, and there are unlimited opportunities. With the support of Fu Yunbin, a famous scientist and academician of Chinese Academy of Sciences, the Institute of Environmental Change was established in 2003, forming a dynamic research team with Fu as the head and Professor Tian Wenshou, Wang Chenghai and Dai Xingang as the main bodies. Since its establishment, the Institute of Environmental Change has made gratifying progress with the support of Mr. Fu, showing a good future development momentum. Strong financial and human support has been obtained in some advantageous scientific research fields, and new scientific research directions are constantly being cultivated. At present, the main research directions and contents of the Institute include:
1. The interaction of terrestrial ecology, climate and human activities: mainly from the role of vegetation in the water cycle of the earth system and the impact of global change on terrestrial ecosystems.
2. Interaction between atmospheric aerosol and climate: This paper mainly studies the interaction between aerosol and cloud and the radiation climate effect of aerosol.
3. Interaction between atmospheric chemical process and climate: mainly from the role of atmospheric chemical process in the climate system and the long-term evolution trend of trace gases in the atmosphere.
4. Research on land surface process: mainly from two aspects: the interaction between freezing process and plateau monsoon and the interaction between land surface process and atmospheric near-surface process.
5. Climate prediction and climate dynamics: This paper mainly discusses the theories and methods of short-term and long-term climate prediction. Director: Academician Xu Jianmin; Deputy Director: Associate Professor Zhang Shuwen and Researcher Guo Ni.
Atmospheric remote sensing refers to the indirect observation of atmospheric elements (including surface parameters) by means of meteorological satellites, weather radars and other detection means. It has the characteristics of wide coverage and high spatial resolution, which complements the shortcomings of conventional meteorological observation. It is one of the fastest growing branches of science since the 1960s, and it is also one of the key technical pillars for the development of atmospheric science. Atmospheric remote sensing is the product of the close combination of modern physics, sensors, computer information technology and atmospheric physics, the product of the combination of high technology and basic research, and the product of research and development closely around the application requirements. Its application theory is based on the understanding of the physical and biochemical processes of the atmosphere and the earth's surface, and the mathematical and physical model of remote sensing of the atmosphere or the earth's surface is established. This model not only establishes a direct model to reflect the quantitative relationship between the received radiation or fluctuation and the atmospheric or surface parameters, but also includes an indirect remote sensing model to obtain the relationship between the atmospheric or surface parameters with the quantitative relationship between the parameters as a constraint condition. Due to the ill-posed problems that often appear in inversion problems, the solution of all these problems also puts forward higher requirements and even challenges for mathematical and physical methods.
The Institute is led by Xu Jianmin, an academician of China Academy of Engineering. At present, there are 3 professors (including lecturers from overseas Cui Ying 1 person), 4 associate professors, lecturers 1 person, and several part-time professors and associate professors. The research direction focuses on the quantitative application of remote sensing products in weather and climate prediction, including the analysis and assimilation of atmospheric data, the inversion and assimilation of land surface parameters, the application of meteorological satellite products, the development and application of environmental remote sensing products, especially the theory and method research of atmospheric data assimilation method and Doppler radar data inversion. Researchers or graduates of our institute can be seen at conferences on data assimilation at home and abroad, and the graduates trained by our institute have been widely praised by employers.
