Jeonju's air quality reflects the flat Jeollabuk-do Mangyeong River plain at 55 metres, with vehicle traffic on surrounding expressways and the automotive manufacturing, traditional food culture, and university corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the regional industrial background influences readings and Jeonju generally maintains moderate South Korean southwestern provincial capital readings throughout most of the year.

These wind events can carry dust in from the surrounding arid landscape. This is most noticeable during spring and autumn wind events.
Are air quality levels in Jeonju 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.
