Short summary

This study investigated the properties of ultra-fine particles (UFPs) and submicron particles (PM₁) in an east Asian urban area. The results indicate that the concentration of PM₁ was elevated during cold seasons, whereas the highest concentration of UFPs was measured in summer. Moreover, UFPs were mostly composed of organics, whereas ammonium and sulfate were the major constituents of PM₁. This study underlines the significance of secondary organic aerosols in UFPs.
