Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a method and system for identifying a high-value ozone generation area. Background Art

[0002] The formation of ozone pollution is closely related to meteorological factors such as light and temperature, and mainly occurs in the summer and autumn when the sun is strong. Ozone precursors such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) emitted by automobile exhaust and industrial enterprises undergo a series of complex photochemical reactions under the action of high temperature and strong light radiation to produce ozone pollutants. As the primary pollutant in summer and autumn in many regions of my country in recent years, its concentration is mainly affected by its two major precursors, VOCs and NOx. Ozone pollution is currently the most important pollution factor affecting the number of good days in cities. Therefore, how to obtain near-ground ozone concentration and promptly and accurately discover ozone pollution sources are important issues currently facing the control of atmospheric ozone pollution.

[0003] In the patent document with application publication number CN113176216A, a method is proposed to comprehensively determine which precursor controls ozone generation through satellite remote sensing monitoring results, and then control ozone generation through targeted emission reduction; in the patent document with application publication number CN112990111A, in order to solve the technical problem that the spatial resolution of satellite data is low and the large amount of volatile organic matter released by vegetation will affect the volatile organic matter data inverted by satellite data, resulting in the inability to fully and accurately identify the high-value area of ​​ozone generation, a method is proposed. A method for identifying high-value ozone generation areas is proposed. By using satellite remote sensing data and normalized vegetation index data, potential high-value ozone generation areas can be quickly locked in a large range, and then combined with multi-source data such as enterprise-related data for comprehensive judgment, high-value ozone generation areas can be accurately identified. In the patent document with application publication number CN110942049A, the tropospheric ozone profile is inverted by using TropOMI ultraviolet hyperspectral data; the near-ground NO2 and HCHO concentrations are obtained by using TropOMI tropospheric NO2 and HCHO column concentration products, combined with the atmospheric chemistry model Geos-Chem, and the concentration ratio of the two is calculated to obtain the near-ground ozone pollution source indicator value; the near-ground ozone concentration is obtained by a multivariate regression model based on NO2, HCHO and ozone monitoring values ​​of ground national control stations; the near-ground ozone concentration result is used to select the ozone heavy pollution area, and the ozone pollution source is identified by combining the near-ground ozone pollution source indicator value and sub-meter high-resolution imagery.

[0004] In the above-disclosed prior art, the identification and monitoring of high-value areas of ground ozone are all based on satellite remote sensing data. Wang Wenpeng et al. conducted a study on the sources of ozone in the surrounding areas of Lanzhou City and found that the meteorological factors that affect the ozone concentration in various regions of Lanzhou City include temperature, relative humidity, wind speed, and boundary layer height. Ozone is a highly mobile secondary pollutant. Its distribution on the surface is affected by many factors and changes rapidly, while the remote sensing data acquisition cycle is long. Therefore, the ground ozone content data obtained by satellite remote sensing technology can only reflect the ozone content level in the area at the time of remote sensing image acquisition, and it is difficult to monitor the changing trend of ozone content in the detection area. To this end, we propose a method and system for identifying high-value areas of ozone generation. Summary of the invention

[0005] The main purpose of the present invention is to provide a method and system for identifying high-value ozone generation areas, which can effectively solve the problems in the background technology.

[0009] The method for dividing the ozone content interval state, temperature state, relative humidity state, wind speed state, and boundary layer height state includes the following steps:

[0010] Step S11: setting the sampling value of any state as Sv;

[0011] Step S12: Create a sample set using the sampled value Sv of the state, denoted as {Sv1, Sv2, ..., Sv n}, where n is the total number of sample values;

[0012] Step S13: Obtain the mean and standard deviation of the sample set, and use the mean and standard deviation to standardize the data. The standardization formula is: In this formula, z is the standard parameter, σ is the variance of the sample data, and μ is the mean of the sample data;

[0013] Step S14: After completing the standardization, the standard parameters are used Adjust the numerical interval to [0,1], and use the function value of f(k) to classify the sample value Sv. The classification mechanism is:

[0014] When f(k) min When ≤f(k)<f(k)1, the sample value Sv is classified as the first level;

[0015] When f(k)1≤f(k)<f(k)2, the sample value Sv is classified as the second level;

[0016] When f(k)2≤f(k)<f(k)3, the sample value Sv is classified as the third level;

[0017] Similarly, when f(k) q ≤f(k)<f(k) max When , the sample value Sv is classified into the tth level;

[0034] In the formula, is the data sequence ρ u,v,w,r The frequency of ozone content transferring from state i to state j in one step.

[0035] Step 4: Obtain the real-time data of various states in the area to be identified at the current moment, use the generated state transition probability matrix to obtain the predicted value of ozone content at the next moment based on the acquired data, and identify the high-value ozone generation area in the area to be identified based on the acquired predicted value. The specific process includes the following steps:

[0036] Step S41: evenly divide the area to be identified into λ×λ grids, and number the grids in a certain order;

[0037] Step S42: Set the current time as t, and the ozone content interval of any grid area in the area to be identified, and the state at the current time t is m t , where m t ∈S, ozone content is C t , current temperature state T t , relative humidity state is H t , wind speed state is W t , the boundary layer height state is B t ;

[0038] Step S43: Generate a random number ε that obeys uniform distribution according to the state of the grid area t , where ε t ∈[0,1];
