Miami's Overtown air quality reflects the historically significant African-American inner urban neighbourhood intersected by the I-95 and I-395 expressway interchanges, with the concentrated expressway vehicle and truck traffic generating elevated diesel PM2.5 and NOₓ in this environmental justice community. The expressway infrastructure's noise and air quality impact maintains consistently elevated readings, while the flat terrain allows some dispersal and the community's ongoing advocacy for environmental equity remains a significant local concern throughout the year.

When is air pollution at its worst in Overtown?
At Overtown, air quality tends to follow Miami's broader seasonal rhythm — daily summer storms tend to scrub the air clean before pollution can build up, whereas the drier months from roughly November through April bring the highest risk of wildfire and prescribed-burn smoke. Sea breezes help disperse pollution on most days, though smoke from inland fires can still drift into populated areas.
Are air quality levels in Overtown 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.
