Flood season ozone prediction system and model construction method

Abstract

The invention discloses a flood season ozone prediction system and a model construction method. The method comprises the following steps: acquiring historical meteorological data and ozone concentration data; performing correlation analysis on each meteorological factor and the ozone concentration data according to the historical meteorological data; screening out key factors according to a correlation analysis result; constructing an ozone concentration prediction model according to the key factors; the system comprises a data acquisition module used for acquiring historical meteorological data and ozone concentration data; the correlation analysis module is connected with the data acquisition module and is used for calculating a correlation coefficient between each meteorological factor and the ozone concentration; the factor screening module is configured to select key meteorological factors according to a correlation coefficient threshold value; the prediction model building module is connected with the factor screening module and used for building a multiple regression model based on the selected key factors; according to the invention, through space-time correlation modeling of the multi-source meteorological data and the ozone concentration, an influence mechanism of meteorological conditions on ozone generation and diffusion can be quantified, and accurate prediction of the ozone concentration is realized.
