Ch'ungmu's air quality benefits from the South Korean southeastern Gyeongnam Hallyeo Maritime National Park coastal position on the South Sea, with consistent Korea Strait and South Sea maritime breezes providing reliable ventilation along this beautiful island-studded coast. Vehicle traffic on surrounding roads and the fishing, tourism, and services corridor contribute modest local sources, while the outstanding maritime exposure generally maintains Tongyeong among South Korea's more moderately ventilated southeastern coastal heritage cities throughout most of the year.

When is air pollution at its worst in Ch’ungmu?
Ch’ungmu usually sees its poorest air quality when vehicle traffic, harbour and shipping traffic, along with seasonal tourism traffic coincide with periods when onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Ch’ungmu 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.
