Broken Arrow's air quality benefits from the flat Oklahoma prairie providing generally good wind dispersal, with vehicle emissions from US-51 and the surrounding Tulsa southeastern suburban corridor contributing local sources. The broader Tulsa metropolitan regional ozone from vehicle and natural gas industry emissions is the primary warm-season concern, while prevailing southerly winds generally maintain moderate conditions.

When is air pollution at its worst in Broken Arrow?
Seasonal changes shape air quality across Broken Arrow. Typically, spring and autumn tend to bring the cleanest, most stable air, while hot, humid summer conditions drive ozone formation, especially during heat waves. Calm, cold winter spells can occasionally allow local pollution to build up before the next weather system clears it.
Are air quality levels in Broken Arrow 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.
