Chuncheon's air quality benefits from the Gangwon-do Chuncheon Lake and Soyang Dam reservoir position at 76 metres, with consistent lake breezes and the surrounding Taebaek mountain backdrop providing reliable ventilation. Vehicle traffic on surrounding roads and the tourism, food culture, and government corridor contribute local sources, while the lake system's natural ventilation and the surrounding highland setting generally maintain Chuncheon among South Korea's more pleasantly ventilated provincial lakeside cities throughout most of the year.

When is air pollution at its worst in Chuncheon?
Air quality in Chuncheon tends to be worse when traffic emissions and seasonal tourism traffic build up and still air allows pollutants to build up. Day-to-day conditions here depend heavily on the weather. Background emissions and local weather both play a role in day-to-day changes.
Are air quality levels in Chuncheon 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.
