Gyeongsan's air quality reflects the South Korean southeastern Geumho River valley position adjacent to Daegu, with vehicle traffic on surrounding roads and the textile, university, and manufacturing corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the Daegu metropolitan industrial regional background influences readings and Gyeongsan generally maintains moderate to elevated South Korean southeastern metropolitan corridor readings throughout the year.

When is air pollution at its worst in Gyeongsan?
Air quality in Gyeongsan tends to be worse when vehicle traffic, manufacturing activity, together with port and shipping activity build up and dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. These episodes tend to cluster in spring and autumn.
Are air quality levels in Gyeongsan 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.
