Marília's air quality reflects its position in the western São Paulo state plateau at 674 metres, with vehicle emissions from the SP-333 and the surrounding coffee processing, agricultural machinery, and food industry contributing local sources. The elevated plateau position aids background dispersal compared to lowland Brazilian cities, while dry season burning from surrounding São Paulo state agricultural land contributes seasonal PM2.5 variation, and the Marília municipality's agribusiness character makes agricultural burning the primary seasonal air quality influence.

When is air pollution at its worst in Marília?
People in Marília tend to notice reduced air quality when eucalyptus and native cerrado remnants pollen peaks, or because of vehicle emissions from the SP-333 and the surrounding coffee processing, agricultural machinery, and food industry; things typically settle down again once the weather pattern shifts.
Are air quality levels in Marília 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.
