Short summary
Urban air pollution is affected by both emissions and meteorology. Using the recent 18 yr long measurements of air pollutants in the East Asian megacity of Seoul, we quantitatively investigated effects on short-term and long-term air quality. Specific synoptic weather patterns were important for episodic PM10 and O3 events, while the long-term decrease in wind speed and the 2008 economic recession played roles in the recent improvement of PM10 and deterioration of O3 air quality in Seoul.
