Short summary
Aerosol chemistry, sources and processes driving the observed temporal and diurnal variations of PM were studied in the Seoul Metropolitan Area (SMA) during spring 2016. An in-depth analysis of the data uncovered that air quality in SMA was influenced strongly by secondary aerosol formation. Also, it was found that the haze episode during spring was mainly caused by a combination of both regional and local factors, which is different from the winter haze mainly caused by intense local sources.
