Waco's air quality reflects the flat Brazos River valley terrain providing generally good wind dispersal, with vehicle emissions from I-35 and the surrounding agriculture and manufacturing industry contributing local sources in this mid-Texas university city. Prevailing southerly Gulf breezes provide warm-season ventilation, while summer ozone from regional Texas vehicle emissions and dust from the surrounding Blackland Prairie agricultural operations are the primary seasonal air quality concerns throughout the year.

When is air pollution at its worst in Waco?
Waco experiences a distinct seasonal swing in air quality. In short, the cleanest air usually comes in the milder shoulder seasons of spring and autumn, whereas extended summer heat waves bring the year's worst ozone readings in the state's biggest metro areas. Gulf Coast humidity and inland heat can each add their own seasonal pollution patterns.
Are air quality levels in Waco 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.
