Gwangju's air quality reflects the Yeongsan River valley's partial enclosure in the Honam Plain, with vehicle traffic on the surrounding expressways and the automotive manufacturing and electronics corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust events, while prevailing westerly winds carry Chinese and Northeast Asian industrial pollution across the Yellow Sea and Gwangju generally maintains moderate to elevated South Korean provincial metropolitan readings throughout most of the year.
