Correlation analysis of AQI characteristics and meteorological conditions in heating season

Abstract

According to the China air quality monitoring platform, the monthly average of the Air Quality Index for monitoring the heating season in Xi'an and the monthly concentration of major atmospheric pollutants in the past three years, the relationship between five major atmospheric pollutants and meteorological conditions was analyzed, the main results are as follows: (1) in the past three years, the air quality in Xi'an heating season was mild pollution, and the most serious degree of pollution was in January each year. (2) The main pollutants in Xi'an were PM2.5 and PM10, but in recent years, the content of pollutants NO2 and O3 has risen sharply, so we should strengthen the protection and the treatment of NO2 and O3. (3) The precipitation has a certain impact on air quality index. (4) The air quality in Xi'an is closely related to meteorological elements.
