Goyang's air quality reflects the flat Gyeonggi-do western Seoul metropolitan corridor adjacent to the DMZ, with vehicle traffic on surrounding expressways and the residential, commercial, and logistics corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the regional Northeast Asian industrial background on westerly winds elevates PM2.5 and Goyang generally maintains moderate to elevated Seoul northwestern metropolitan suburban readings throughout the year.

When is air pollution at its worst in Goyang?

In Goyang, traffic on the surrounding roads along with harbour and shipping traffic are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. This is most noticeable during spring and autumn wind events.

Are air quality levels in Goyang 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.
