Dunwoody's air quality reflects the northern Atlanta metropolitan corridor in DeKalb County, with vehicle emissions from I-285 and GA-400 and the surrounding affluent residential and corporate campus character contributing local sources. The Chattahoochee River corridor provides natural ventilation, while the broader Atlanta metropolitan ozone challenge from the vast highway network is the primary warm-season concern throughout the summer ozone season and the corporate campus character generally maintains moderate emission levels.

When is air pollution at its worst in Dunwoody?
Dunwoody's air quality follows a clear seasonal pattern: the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, but summer heat, humidity, and emissions from surrounding forests combine to drive ozone levels up. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Dunwoody 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.
