Muan's air quality reflects the South Korean southwestern Jeonnam coastal position adjacent to Muan International Airport, with vehicle traffic on surrounding roads and the airport aviation operations, agriculture, and government corridor contributing local sources. Yellow Sea breezes provide coastal ventilation, while seasonal Chinese dust transport elevates PM10 and the aviation operations represent the most distinctive local emission source throughout the year.

When is air pollution at its worst in Muan?
Air quality in Muan tends to be worse when road traffic, aircraft operations at the local air base, along with agricultural burning build up and dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Muan 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.
