Analysis of characteristics ofmulti-time scale variation of inhalable particulate concentration in Taizhou
Based on the air quality data and meteorological data of Taizhou city, this paper analyzes the annual, seasonal and daily variation characteristics of inhalable particulate matter in Taizhou city through statistical analysis of the concentration of inhalable particulate matter. The results showed that in recent years, the annual mean values of inhalable particulates and fine particulates in Taizhou showed a significant downward trend. The monthly mean concentrations of PM2. 5 and PM10 showed the trend of higher level in winter and spring, lower level in summer and autumn, and the diurnal variation curves showed double peaks. The peak time of morning and evening appeared at 8 am and 9 pm, respectively, and the lowest concentration was at noon.
