Kunsan's air quality reflects the flat Jeollabuk-do Yellow Sea coastal position at the Mangyeong River delta, with vehicle traffic on surrounding roads and the Kunsan Industrial Estate's chemicals, paper, and manufacturing corridor contributing elevated industrial emissions. Yellow Sea breezes provide coastal ventilation, while seasonal Chinese dust transport elevates PM10 and the industrial estate's manufacturing character maintains moderate to elevated South Korean western coastal industrial readings throughout most of the year.

When is air pollution at its worst in Kunsan?
In Kunsan, traffic emissions, petrochemical and refining operations, as well as textile and manufacturing operations are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Kunsan 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.
