Commerce City's air quality reflects Denver's northern metropolitan corridor, with the Suncor Energy refinery — Colorado's largest petroleum operation — generating elevated SO₂, benzene, and industrial PM2.5 alongside vehicle traffic on I-76. The flat Colorado plains to the east provide some dispersal, while the refinery's industrial scale and the Front Range temperature inversion problem make Commerce City Denver's most distinctively industrial-defined urban environment throughout the year.

When is air pollution at its worst in Commerce City?
Commerce City sees air quality change through the year: a brief window in autumn tends to bring the year's best air, before winter inversions set in, but summer brings regional wildfire smoke, while winter brings its own inversion-driven pollution episodes. Higher-elevation, more exposed locations generally avoid the worst of the valley inversion episodes.
Are air quality levels in Commerce City 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.
