Columbia's air quality reflects its position on the rolling mid-Missouri prairie between Kansas City and St. Louis, with vehicle emissions from I-70 and US-63 and the University of Missouri campus traffic contributing local sources. The gently rolling terrain provides reasonable wind dispersal, while summer regional ozone from Midwest agricultural and vehicle sources is the primary warm-season concern throughout the year.

When is air pollution at its worst in Columbia?
Air quality across Columbia rises and falls with the seasons. Typically, winter generally brings the cleanest air, aside from brief inversion episodes during calm cold spells, while both spring planting and autumn harvest bring short bursts of elevated dust and smoke. Wide-open terrain generally helps disperse pollution quickly once the wind picks up.
Are air quality levels in Columbia 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.
