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.

When is air pollution at its worst in Killeen?
Like most US cities, Killeen sees air quality shift from season to season — the mildest, cleanest stretch typically falls in spring or autumn, whereas long, hot summers bring the highest ozone risk, especially across the major urban corridors. 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
