Itapevi's air quality is significantly influenced by its position in the western Greater São Paulo metropolitan ring, with vehicle emissions from the Rodovia Castello Branco and the surrounding mixed industrial and residential character of this rapidly growing satellite municipality contributing elevated NOₓ and PM2.5. The Greater São Paulo basin's poor dispersal characteristics affect the entire western corridor, while the Cotia and Carapicuíba industrial zones to the east compound the local emission burden under the region's prevailing easterly wind conditions.

When is air pollution at its worst in Itapevi?
Residents in Itapevi are most likely to notice reduced air quality when eucalyptus and introduced urban trees pollen peaks, or due to vehicle emissions from the Rodovia Castello Branco and the surrounding mixed industrial and residential character of; background levels usually settle back down once the season changes.
Are air quality levels in Itapevi 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.
