Atibaia's air quality benefits from its elevated position in the Serra da Cantareira foothills at 765 metres in northern greater São Paulo, with the Atlantic Forest mountain setting providing cleaner background air than the metropolitan core. Vehicle emissions from the SP-063 Fernão Dias highway and the surrounding floriculture, technology research, and weekend residential corridor contribute local sources, while the elevated position and the Cantareira's forested backdrop generally maintain better conditions than the São Paulo metropolitan average throughout most of the year.

When is air pollution at its worst in Atibaia?
You're most likely to notice worse air in Atibaia when Araucaria pine and eucalyptus pollen peaks, or due to vehicle emissions from the SP-063 Fernão Dias highway and the surrounding floriculture, technology research; outside those spells, this remains one of the more consistently clean-air places to be.
Are air quality levels in Atibaia 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.
