Gwangmyeongni's air quality reflects the flat Gyeonggi-do western Seoul metropolitan corridor position in Gwangmyeong, with vehicle traffic on surrounding expressways and the residential, commercial, and logistics 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 western suburban readings throughout the year.

When is air pollution at its worst in Gwangmyeongni?
Gwangmyeongni usually sees its poorest air quality when traffic on the surrounding roads together with harbour and shipping traffic coincide with periods when windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Such events are most common in the drier shoulder seasons.
Are air quality levels in Gwangmyeongni 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.
