Short summary

Five episodes were divided based on meteorological conditions and chemical composition. The clear episodes (EP-2 and EP-4) featured low light extinction with fewer pollutants, which are mostly externally mixed. In contrast, EP-1 and EP-5 were impacted by the industrial activities and biomass burning through the southern air mass, respectively. Soot at the fog period detected in EP-3 was mostly internally mixed with sulfates and nitrates.
