Catalão's air quality reflects the southeastern Goiás plateau at 840 metres, with the Vale mining and phosphate fertiliser manufacturing operations contributing elevated mineral dust PM10 and industrial emissions alongside vehicle emissions from the BR-050. Dry season burning from surrounding Cerrado agricultural land contributes seasonal PM2.5 variation throughout the year.

Is air quality bad in Catalão right now?
On 9 August 2026, overall air quality in Catalão is fair. AQI is the main air quality indicator at 36.9/100. Pollution peaks around 8:00 PM (PM2.5: 36.9/100).

When is air pollution at its worst in Catalão?
In Catalão, reduced air quality is most noticeable when native cerrado trees and soybean farmland pollen peaks, and on days affected by the Vale mining and phosphate fertiliser manufacturing operations; the clearest air tends to follow a change in wind direction or rainfall here.
Are air quality levels in Catalão 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.
