Incheon's air quality reflects South Korea's Yellow Sea coastal position adjacent to Seoul's Incheon International Airport, with the airport's concentrated aviation operations and vehicle traffic on surrounding expressways generating elevated NOₓ alongside the surrounding steel, petrochemical, and logistics corridor. Yellow Sea maritime breezes provide coastal ventilation, while seasonal Chinese dust transport and the regional Northeast Asian industrial background elevate PM10 during spring dust episodes throughout the year.

When is air pollution at its worst in Incheon?
The biggest local contributors to pollution in Incheon are road traffic, aviation activity from the nearby airport, along with heavy industrial and chemical processing, particularly once windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Incheon 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.
