Killeen's air quality reflects the Central Texas Blackland Prairie's flat terrain providing generally good wind dispersal, with vehicle emissions from US-190 and the heavy military vehicle traffic from Fort Cavazos, one of the US Army's largest installations, contributing elevated PM10 and NOₓ. The surrounding Lampasas Cut Plain and Balcones Escarpment create modest topographic variation, while summer ozone from regional Texas vehicle emissions is the primary warm-season concern.

Dust from West Texas can occasionally drift across the state and add to particulate levels.

Are air quality levels in Killeen 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.
