Anseong's air quality reflects the flat Gyeonggi-do Anseong River plain position, with vehicle traffic on surrounding roads and the manufacturing, 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 Anseong generally maintains moderate South Korean central Gyeonggi provincial corridor readings throughout most of the year.

When is air pollution at its worst in Anseong?
The biggest local contributors to pollution in Anseong are traffic emissions, textile and manufacturing operations, together with farming and agricultural processing, particularly once windblown dust events occur. Dust carried on these winds adds substantially to particulate levels. Such events are most common in the drier shoulder seasons.
Are air quality levels in Anseong 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.
