The School of Environment organized a number of units in Sichuan and Chongqing to jointly carry out the winter comprehensive observation experiment for the first time

In order to explore the regional air pollution joint prevention and control mechanism and the demonstration application of the research results in the Chengdu-Chongqing area, and deeply analyze the causes of regional pollution in winter, with the strong support of the Sichuan-Chongqing ecological environment department, in mid-December 2021, Peking University Environmental Science and Engineering The college organizes Chengdu Environmental Protection Research Institute, Sichuan Ecological Environment Monitoring Station, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Sichuan Ecological Environment Research Institute, Chongqing Ecological Environment Monitoring Center, Chongqing Ecological Environment Research Institute, Sichuan More than 10 scientific research institutes including the University, Chengdu University of Information Technology, Sichuan Environmental Policy and Planning Research Institute, relying on the National Key R&D Program "Chengdu-Chongqing Air Pollution Joint Prevention and Control Technology and Integration Demonstration" led by the School of Environmental Science and Engineering, Peking University " and "Chengdu City Fine Particulate Matter and Ozone Pollution Collaborative Prevention and Control "One City One Policy" Station Tracking Research Project", carried out winter comprehensive observation experiments at 11 stations in Chengdu, Deyang, Chongqing and other cities, aiming to clarify the hills in the Chengdu-Chongqing Basin The key physical and chemical processes of atmospheric composite pollution and the _causes and sources _of heavy pollution under the meteorological background of regional, high humidity and high still wind frequency A starting point for urban and regional air pollution control strategies
