Pyeongtaek's air quality reflects the flat Gyeonggi-do western coastal plain position adjacent to the US Army Camp Humphreys military base and Pyeongtaek Port, with vehicle traffic on surrounding roads and the military aviation, port, and manufacturing corridor contributing elevated NOₓ. Yellow Sea breezes provide coastal ventilation, while seasonal Chinese dust transport elevates PM10 and the military aviation operations represent the most distinctive local emission source throughout the year.

When is air pollution at its worst in Pyeongtaek?
Pyeongtaek usually sees its poorest air quality when traffic emissions, aircraft operations at the local air base, and manufacturing activity coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Pyeongtaek 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.
