Rowlett's air quality reflects the DFW metroplex's northeastern Dallas County corridor adjacent to Lake Ray Hubbard, with vehicle emissions from I-30 the primary local source in this major Dallas eastern suburb. The lake provides some local ventilation, while the broader DFW metropolitan ozone from vehicle and Barnett Shale natural gas emissions affects the entire eastern corridor and summer ozone from the dense metroplex traffic is the primary warm-season air quality concern.

When is air pollution at its worst in Rowlett?
Air quality across Rowlett rises and falls with the seasons: spring and autumn generally bring more moderate, cleaner conditions between the extremes of summer and winter cedar season, but 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 Rowlett 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.
