Ich'ŏn's air quality reflects the flat Gyeonggi-do southern Gyeonggi corridor position, with vehicle traffic on surrounding roads and the SK Hynix semiconductor manufacturing — Icheon being one of Korea's major semiconductor hubs — and logistics corridor contributing elevated industrial emissions. Seasonal Chinese dust transport elevates PM10, while the regional industrial background influences readings and Icheon generally maintains moderate to elevated South Korean central Gyeonggi industrial corridor readings throughout the year.

Frequently Asked Questions
Is air quality bad in Ich’ŏn right now?
On 16 July 2026, overall air quality in Ich’ŏn is poor. AQI is the main air quality indicator at 64.8/100. Pollution peaks around 2:00 PM (O3: 64.8/100).
Will air quality be worse tomorrow in Ich’ŏn?
On 17 July 2026, air quality conditions in Ich’ŏn will be worse than today, with AQI forecast at very poor at 90.4/100. Pollution peaks around 3:00 PM (O3: 90.4/100).
When is air pollution at its worst in Ich’ŏn?
The biggest local contributors to pollution in Ich’ŏn are traffic on the surrounding roads, manufacturing and food processing, along with port and shipping activity, particularly once windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. This is most noticeable during spring and autumn wind events.
Are air quality levels in Ich’ŏn 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.
