Convenient early warning method for atmospheric ozone pollution

Abstract

The invention discloses a convenient early warning method for atmospheric ozone pollution, and the method comprises the steps: (1) obtaining physical parameters, including air temperature, total solar radiation irradiance, cloud amount, particulate matter concentration and nitrogen oxide concentration, affecting the generation of atmospheric ozone through analyzing the external conditions of the generation of atmospheric ozone; (2) determining inflection point values of the physical parameters according to atmospheric ozone generation conditions, and assigning values after interval division; (3) acquiring historical data of physical parameters related to atmospheric ozone generation in a to-be-warned region within a period of time, and obtaining a weight of each physical parameter by utilizing a constructed Logistic regression model; and (4) calculating an ozone concentration influence factor result value according to the interval assignment result and the weight of the physical parameters, and determining an early warning interval and a corresponding early warning level. The method provided by the invention is convenient to implement, improves the early warning advance, and has certain guiding significance for atmospheric ozone pollution prevention and control work.

Description

technical field [0001] The invention belongs to the field of atmospheric environment monitoring and air pollution control, and in particular relates to a convenient early warning method for atmospheric ozone pollution. Background technique [0002] With the continuous deepening of structural emission reduction measures, the large-scale promotion of environmental protection technologies, and the gradual popularization of clean energy, the concentration of particulate matter has been reduced year by year. However, ozone pollution has "increased instead of falling", which has become an urgent problem to be solved in the next stage of air pollution prevention and control. The causes of atmospheric ozone pollution are complex, which brings great difficulties to the actual treatment work. [0003] At present, the early warning method of atmospheric ozone pollution is mainly direct monitoring, that is, the feedback result data is obtained through real-time monitoring of the ozone ...

AI Technical Summary

Problems solved by technology

The effect of this real-time monitoring and early warning method is obviously negligible. This is because once the external conditions are met, the ozone generation rate is very fast, resulting in the failure to take timely control measures, which greatly affects the control efficiency.

Another method is that the air quality numerical model can also provide an early warning function for some atmospheric ozone pollution, but the calculation process is complicated, it depends heavily on computer performance, and the cost is high
