Dongducheon's air quality reflects the Gyeonggi-do northern Seoul metropolitan corridor adjacent to US Army Camp Casey, with vehicle traffic on surrounding roads and the military base operations and residential character contributing elevated NOₓ. The surrounding Gwangju and Chuncheon mountain ranges create topographic variation, while seasonal Chinese dust transport and the broader Seoul metropolitan regional background maintain moderate South Korean northern DMZ corridor readings throughout most of the year.

When is air pollution at its worst in Dongducheon?
Dongducheon usually sees its poorest air quality when traffic on the surrounding roads, airport and aviation operations, along with fishing fleet activity coincide with periods when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Such events are most common in the drier shoulder seasons.
Are air quality levels in Dongducheon 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.
