Abstract

The invention provides an urban atmosphere emission list inversion method, system and device and a storage medium, and the method comprises the steps: obtaining an initial emission list of urban atmosphere, and building an air quality source analysis model based on a meteorological model; inputting the initial emission list into an air quality source analysis model for simulation so as to obtain PAMS concentration contribution, and combining PAMS emission in the initial emission list so as to obtain a coefficient relationship between the concentration and the emission; pAMS observation concentrations at multiple moments are obtained, and the optimal solution of the PAMS emission is obtained through inversion according to the least square method in combination with the coefficient relation; replacing the optimal solution of the emission amount into the emission list, and repeating the steps to obtain a corresponding PAMS simulation concentration; and when a preset condition is met, iteration is stopped so as to obtain the optimal solution of the final discharge amount of the PAMS. Compared with an existing emission list calculation method, the method has the advantages that as many as 57 PAMS substances of VOCs can be inverted; the number of stations needing observation is small, and only one piece of ground VOCs observation equipment is needed; and inversion areas and cities are not limited, so that the cost is relatively low.

Description

technical field [0001] This application relates to the field of air pollution control, in particular to a method, system, equipment and storage medium for inversion of urban air emission inventory. Background technique [0002] Volatile organic compounds (VOCs) are major players in atmospheric photochemical processes and 3 And the key precursors of secondary organic aerosol generation, studies have shown that VOCs can contribute 30% to 50% to global ozone, and contribute 2.5 to 47.1 Tg to global SOA per year. Studying the pollution level and concentration composition of urban atmospheric volatile organic compounds and identifying the key active components that affect urban air quality are the basis for exploring the sources of pollution and explaining the photochemical reaction process. An accurate emission inventory of volatile organic compounds can help researchers accurately analyze the formation mechanism of atmospheric photochemical pollution, and also provide governme...
