Particulate Matter Concentrations over South Korea: Impact of Meteorology and Other Pollutants

Air pollution is a serious challenge in South Korea and worldwide, negatively impacts human health mortality rates. To assess air quality the spatiotemporal characteristics of atmospheric particulate matter (PM), PM concentrations were compared with meteorological conditions other airborne pollutants over from 2015 to 2020, using different linear non-linear models such as regression, generalized additive, multivariable regression models. The results showed that played significant role formation, transportation, deposition pollutants. PM2.5 levels peaked January, while PM10 April. Both at their lowest July. Further, was highest during winter, followed by spring, autumn, summer, whereas spring summer. correlated temperature, relative humidity, precipitation. Wind speed had an inverse relationship quality; zonal vertical wind components positively PM, respectively. Furthermore, CO, black carbon, SO2, SO4 positive PM. impact transboundary on concentration also elucidated mass trajectories.
