Abstract

The invention belongs to the technical field of environmental monitoring and relates to an atmospheric pollution tracing system. The system comprises an emission source input module used for inputtingemission data, an initialization module used for setting the initial concentration of pollutants, an atmospheric chemistry module used for simulating a chemical process in an air mass movement process according to the input emission data, an atmospheric physical module used for inputting meteorological parameters and simulating a physical process in the air mass movement process according to themeteorological parameters, and a result output module used for outputting the concentration of the pollutants and the rate of the atmospheric chemical reaction process, quantifying the contribution ofregion transmission and local generation to the O3 concentration of a target region, and quantifying the contribution of different chemical processes to the O3 concentration of the target region. According to the system, atmospheric physical and chemical processes are comprehensively considered, the evolution of the pollutant concentration and the chemical reaction rate of gas mass in the movement process in the space-time scale is restored, a discharge area causing ozone pollution in the target area is accurately located, a precursor and a discharge department are optimally controlled, and scientific support is provided for formulating the control measures of the ozone pollution in the target area.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring and relates to an air pollution traceability system. Background technique [0002] In recent years, due to rapid urbanization and industrialization, near-surface O 3 The pollution problem is getting worse. According to the air quality monitoring results released by the Ministry of Ecology and Environment of the People's Republic of China, since 2013, key pollutants included in routine monitoring such as SO 2 , NO 2 , CO, PM 2.5 , PM 10 The pollution situation has been continuously and significantly improved, except for O 3 The concentration is in a state of "not falling but increasing", which has become a major problem in winning the battle to defend the blue sky. o 3 What makes pollution prevention and control so challenging is that it is difficult to pinpoint the cause of O 3 The source of pollution is embodied in two key scientific issues: first, O 3 Atmospheric life i...
