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.

When is air pollution at its worst in Gwangju?
Air quality in Gwangju tends to be worse when traffic on the surrounding roads, manufacturing activity, along with shipbuilding and port operations build up and dry, windy weather picks up. These wind events can carry dust in from the surrounding arid landscape. This is most noticeable during spring and autumn wind events.
Are air quality levels in Gwangju based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
