Guri's air quality reflects the flat Gyeonggi-do Hangang River eastern Seoul metropolitan corridor, with vehicle traffic on surrounding expressways and the manufacturing, residential, and commercial character contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the broader Seoul metropolitan regional background maintains moderate to elevated South Korean metropolitan eastern suburban readings throughout the year.

When is air pollution at its worst in Guri?
Guri usually sees its poorest air quality when road traffic, light manufacturing, as well as port and shipping activity coincide with periods when dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. These episodes tend to cluster in spring and autumn.
Are air quality levels in Guri 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.
