Review of Atmospheric Chemistry and Environment Research Work in Recent 30 Years———In Commemoration of the 50 Anniversaries of CAMS Establishment

Research work associated with the atmospheric chemistry and environment undertaken in the CAMS in recent 30 years is reviewed. The work is mainly supported by the key projects from the National Natural Science Foundation and by the "973" project from the Ministry of Science and Technology of China. The main significantly creative achievements are as follows: The first discovery of the summer total ozone valley occurring over the Tibetan Plateau; with the consideration of the environment, ecosystem, climate as an integrated system, impacts from anthropogenic activities on the environment through changing the status of the ecosystem, and its influencing on the regional climate is better identified in China; understanding of the mechanisms of the atmospheric pollution in Beijing city and the methods of modulation of the pollution are much improved. The achievements of solving the critical difficulties of the atmospheric environmental problems in Beijing are creatively approached based on the 3-dimension observations, with the integrated analysis of statistics and dynamics, the surface and satellite observations, and the model simulations; the first continent Global Atmospheric Watch (GAW) baseline observatory is established at Mt Waliguan, Qinghai Province, initialing the GAW routine observations in China. In conclusion, the work of 30 years in CAMS contains almost all the important topics of the atmospheric chemistry and their frontier researching contexts. These topics are listed as greenhouse gases, total ozone, reactive gases, aerosols, acid rains, the development and applications of atmospheric chemistry model simulations, the forecast methods of air quality and the assessment of atmospheric environment etc. The advances of atmospheric chemistry in CAMS are much related to the constructions of monitoring network operated by the CMA. The establishments of monitoring networks of GAW, acid rain, total ozone, dust storm have provided CAMS with a common platform for atmospheric chemistry researches.
