Samch'ŏk's air quality reflects the South Korean Gangwon East Sea coastal position on the Osip River delta, with vehicle traffic on surrounding roads and the cement — Samcheok being Korea's cement capital — and port corridor generating elevated industrial dust PM10 and PM2.5. Consistent East Sea maritime breezes provide coastal ventilation, while the cement manufacturing operations' extraordinary scale relative to the local urban population makes Samcheok South Korea's most distinctively cement manufacturing-defined coastal urban environment throughout the year.

When is air pollution at its worst in Samch’ŏk?
Air quality in Samch’ŏk tends to be worse when traffic on the surrounding roads, steel, cement, and chemical production, and manufacturing activity build up and dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Samch’ŏk 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.
