Pohang's air quality reflects the South Korean eastern Yeongnam coast on the East Sea, with vehicle traffic on surrounding expressways and the POSCO steel complex — one of the world's largest integrated steel mills — generating elevated industrial SO₂ and PM2.5 alongside vehicle sources. East Sea maritime breezes provide coastal ventilation, while the steel complex's extraordinary industrial scale relative to the urban population makes Pohang South Korea's most distinctively steel manufacturing-defined coastal urban environment throughout the year.

When is air pollution at its worst in Pohang?
The biggest local contributors to pollution in Pohang are vehicle traffic, petrochemical and refining operations, together with light manufacturing, particularly once windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Pohang 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.
