Recently due to meteorological and air quality conditions, cases of high concentration of particulate matter are steadily increasing. Air pollutants including particulate matter are greatly affected by meteorological fluctuations, and those act as precursors of particulate matter, so the meteorological and air quality are closely related to particulate matter.
In this study, the data of the meteorological (temperature, precipitation, wind speed, relative humidity, solar radiation), air quality (SO2, NO2, O3, CO), and particulate matter (PM2.5, PM10, PM2.5/PM10), observed for 5 years from 2015 to 2019 in Seoul, are used in order to examine the effects of meteorological and air quality conditions on particulate matter.
Particulate matter has a positive correlation between the increase of air quality and meteorological conditions, such as temperature, solar radiation, and relative humidity, while precipitation and wind speed are negatively correlated with particulate matter. In the principal component analysis(PCA), the first principal component factor was composed of items that have a direct relationship with solar radiation in spring and summer, and air pollutants in autumn and winter.
According to the analysis results, the concentration of particulate matter changes in various ways depending on the meteorological and air quality conditions, but it is difficult to separate and analyze individual effects because the meteorological and air quality have a close relationship. Therefore, it seems necessary to have a system for integrated management of air pollutants and meteorological factors such as managing the emission of air pollutants in accordance with meteorological conditions.
