Tangjin's air quality reflects the South Korean Chungnam Asan Bay coastal position adjacent to the Hyundai Steel Dangjin Works — one of Korea's largest integrated steel plants — generating elevated industrial SO₂ and PM2.5 alongside vehicle traffic on surrounding roads. Yellow Sea breezes provide coastal ventilation, while the steel complex's industrial scale represents Dangjin's most distinctive local air quality contribution and seasonal Chinese dust transport elevates PM10 throughout most of the year.

On 10 August 2026, overall air quality in Tangjin is medium. AQI is the main air quality indicator at 43.0/100. Pollution peaks around 3:00 PM (O3: 43.0/100).
Will air quality be worse tomorrow in Tangjin?
On 11 August 2026, air quality conditions in Tangjin will be worse than today, with AQI forecast at poor at 63.3/100. Pollution peaks around 5:00 PM (O3: 63.3/100).
When is air pollution at its worst in Tangjin?
Pollution in Tangjin typically rises when vehicle traffic, steel, cement, and chemical production, and port and shipping activity combine, especially once 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 Tangjin 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.
