Uijeongbu's air quality reflects the flat Gyeonggi-do northern Seoul metropolitan corridor adjacent to US Army Garrison Casey, with vehicle traffic on surrounding expressways and the military, residential, and commercial character contributing elevated NOₓ. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the broader Seoul metropolitan regional background maintains moderate to elevated Seoul northern metropolitan suburban readings throughout the year.

Are air quality levels in Uijeongbu 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.
