Tatuí's air quality reflects the São Paulo state interior plateau at 620 metres, with vehicle emissions from the SP-270 and surrounding concrete pipe manufacturing and agribusiness contributing local sources. Dry season burning from surrounding agricultural land contributes seasonal PM2.5 variation, while the building materials manufacturing operations add distinctive construction dust emissions throughout the year.

When is air pollution at its worst in Tatuí?
People in Tatuí tend to notice reduced air quality when eucalyptus and native cerrado-Atlantic Forest transitional species pollen peaks, or because of vehicle emissions from the SP-270 and surrounding concrete pipe manufacturing and agribusiness; things typically settle down again once the weather pattern shifts.
Are air quality levels in Tatuí 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.
