Mogi Guaçu's air quality reflects the São Paulo state interior plateau valley, with vehicle emissions from the SP-340 and surrounding sugarcane and paper industry contributing local sources. Dry season burning from surrounding agricultural land contributes seasonal PM2.5 variation, while the regional São Paulo state agricultural burning creates the primary seasonal air quality influence throughout the year.

When is air pollution at its worst in Mogi Guaçu?
Reduced air quality in Mogi Guaçu is most likely when eucalyptus and the river corridor vegetation pollen peaks, alongside periods of vehicle emissions from the SP-340 and surrounding sugarcane and paper industry; conditions usually ease once the wet season or windier weather returns.
Are air quality levels in Mogi Guaçu 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.
