Yŏju's air quality reflects the flat Gyeonggi-do Namhan River valley position, with vehicle traffic on surrounding roads and the ceramic heritage — Yeoju being Korea's ceramics capital — agricultural, and logistics corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the regional industrial background influences readings and Yeoju generally maintains moderate South Korean central Gyeonggi provincial corridor readings throughout most of the year.

When is air pollution at its worst in Yŏju?
In Yŏju, road traffic, textile and manufacturing operations, and farming and agricultural processing are the main local sources, with conditions worsening when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. This is most noticeable during spring and autumn wind events.
Are air quality levels in Yŏju 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.
