Sertãozinho's air quality reflects the São Paulo state sugarcane belt, with ethanol distilleries and sugar mills contributing organic aerosols. Dry season sugarcane burning historically generated severe seasonal PM2.5, though mechanised harvesting has progressively reduced this impact, while the plateau position at 546 metres aids background dispersal throughout the year.

When is air pollution at its worst in Sertãozinho?
Air quality dips in Sertãozinho mostly track sugarcane crop vegetation and native cerrado remnants pollen peaks and periods of ethanol distilleries and sugar mills; the picture usually improves again once the season turns.
Are air quality levels in Sertãozinho 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.
