Itu's air quality reflects its position in the Tietê river valley of the São Paulo state interior, with vehicle emissions from the SP-075 Castelo Branco highway and the surrounding sugarcane, paper, and light industrial operations contributing local sources in this historic colonial city. The Tietê valley topography creates modest enclosure, while dry season burning from surrounding São Paulo state sugarcane and agricultural land contributes seasonal PM2.5 variation, and the broader Campinas-Sorocaba metropolitan influence shapes the regional air quality background.

Is air quality bad in Itu right now?
On 9 August 2026, overall air quality in Itu is good. AQI is the main air quality indicator at 20.0/100. Pollution peaks around 12:00 AM (O3: 20.0/100).

When is air pollution at its worst in Itu?
Air quality dips in Itu mostly track eucalyptus and native cerrado remnants pollen peaks and periods of vehicle emissions from the SP-075 Castelo Branco highway and the surrounding sugarcane, paper; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Itu 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.
