Pueblo's air quality reflects the Arkansas River valley's partial enclosure between the Front Range and the Wet Mountains, with the EVRAZ steel mill generating elevated SO₂ and PM2.5 alongside vehicle emissions from I-25. The valley's topographic concentration under winter inversions traps industrial and vehicle emissions, while summer ozone from the Colorado Front Range corridor is the primary warm-season concern.

When is air pollution at its worst in Pueblo?
Pueblo sees air quality change through the year, as spring and autumn generally bring the cleanest, most stable air; by contrast, wildfire smoke drifting in from across the region is the main summer concern, while winter inversions can trap pollution locally. Valley and basin locations are especially prone to these winter inversion episodes compared to more exposed, higher terrain.
Are air quality levels in Pueblo 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.
