Local Environmental Conditions
Air pollution in Dallas comes mainly from traffic. Vehicles, construction equipment, trains and aircraft produce about 60% of the emissions that form ozone in North Texas, and busy routes such as I-35E, I-30 and the LBJ Freeway carry heavy traffic through the city, alongside DFW and Love Field airports. Industry plays a smaller role than in Houston. Most summers, dust from the Sahara crosses the Atlantic and leaves a haze over Dallas, and smoke from fires in Mexico and Central America sometimes drifts north.
Ozone is the main air quality concern in Dallas, and the region does not meet the federal ozone standard. The ozone season runs from March to November, with the most unhealthy days on hot, sunny, still afternoons from May to September, when Ozone Action Days are often called. Saharan dust usually arrives between late June and mid-August, while smoke from fires in Mexico is most common in spring. From December to February, cooler weather, averaging around 9°C in January, usually brings a break from ozone in Dallas.

When is air pollution at its worst in Dallas?
Ozone is the main air quality concern in Dallas, and the region does not meet the federal ozone standard. The ozone season runs from March to November, with the most unhealthy days on hot, sunny, still afternoons from May to September, when Ozone Action Days are often called. Saharan dust usually arrives between late June and mid-August, while smoke from fires in Mexico is most common in spring. From December to February, cooler weather, averaging around 9°C in January, usually brings a break from ozone in Dallas.
Are air quality levels in Dallas 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.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
