Problems solved by technology

However, this type of method requires a high-resolution emission inventory of pollution sources in the research area and its surroundings as the most basic input parameter, and this is currently one of the most difficult problems to be solved in major cities in my country
At the same time, the use of WRF-Models-3 / CMAQ is very complicated, the threshold is extremely high, and the calculation of the sensitivity of ozone generation and the control ratio of its precursors requires a lot of computer resources and calculation time, and only a few scientific research institutions can calculate

Embodiment 1

[0053] This embodiment provides a method for judging the sensitivity of ozone generation and the control of precursors. The theoretical innovation is carried out on the basis of the cognition of the cycle effect of the ozone concentration at the bottom of the troposphere, that is, relative to working days, on non-working days, although some ozone The concentration of precursors (such as VOCs, CO and NOx) decreased, but the ozone concentration value increased significantly, not only by comparing the changes in source emissions on weekdays and weekends, but also providing practical observations for the sensitivity study of model source emissions , and to a certain extent, the impact factors of urban ozone production can be obtained, providing a scientific basis for the formulation of ozone control policies, and overcoming the problem of representative selection differences and applicable to large sample data. Specifically, such as figure 1 As shown, the method includes:

Abstract

The invention discloses a method and a device for ozone generation sensitivity determination and precursor controlling, a storage medium and a terminal. The method comprises: calculating the value ofa parameter R't which characterizes photochemical reaction sensitivity at time t; using the maximum value of the absolute value of the R't to perform numerical value normalization on the R't; determining the ozone photochemical reaction sensitivity at the time t according to the positive and negative and the value of a calculation result of Rt; and calculating reduction control ratios of emissionsof ozone precursors VOCs and NOx in an ozone pollution control time period of the city according to Rt value statistics TVOCs-limited and TNOx-limited of VOCs-limited and NOx-limited in an ozone pollution to-be-controlled time period in a city. The method does not need a high-precision air pollution source emission inventory, weather data, unconventional monitoring air component data and the like, and has an extremely-low data input threshold.

Description

technical field [0001] The invention relates to a method, a device, a storage medium and a terminal for judging the sensitivity of ozone generation and controlling precursors. Background technique [0002] In recent years, my country's atmospheric ozone pollution has been intensified, and has become 2.5 Another important pollutant that plagues urban air quality improvement and standard management. Ozone near the ground is a secondary air pollutant generated after photochemical reactions, especially in summer and autumn. The days when ozone is the primary pollutant in cities in my country are mainly concentrated in May to October. As a strong oxidant, ozone's distribution and changes in the troposphere directly affect the concentration and lifespan of other chemical substances, free radicals, etc., and can also change the temperature structure of the troposphere by absorbing ultraviolet light from the sun, thereby affecting the cycle and balance of atmospheric chemistry. Ke...
