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.

When is air pollution at its worst in Noksan?

In Noksan, traffic emissions, manufacturing activity, along with agricultural burning are the main local sources, with conditions worsening when dry, windy weather picks up. 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.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
