Abstract
The characteristics of visual air quality in Seoul have been investiga ted from March to November 1993. Optical properties, meteorological pa rameters, and particle characteristics were measured and analyzed. On the average, light scattering by particles is the dominant process in light extinction. Fine particle mass concentration, and the fraction o f sulfate, nitrate and ammonium ions in the particles were found to pl ay a major role in influencing the occurrence of a smog episode in Seo ul. The role of ambient relative humidity on Seoul visibility is discu ssed.
