Noksan in Chungnam reflects the South Korean Chungnam coastal position, with vehicle traffic on surrounding roads and the agricultural and light manufacturing operations contributing local sources. Yellow Sea breezes provide coastal ventilation, while seasonal Chinese dust transport elevates PM10 and the regional agricultural background maintains moderate South Korean Chungnam coastal corridor readings throughout most of the year.

These wind events can carry dust in from the surrounding arid landscape. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Noksan 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.
