Poços de Caldas' air quality benefits from its elevated position on the Minas Gerais plateau at 1,184 metres, with the surrounding Serra da Canastra foothills providing clean background air on most days. Vehicle emissions from the BR-267 and the surrounding mining and ceramics industry contribute local sources, while the elevated position and the natural thermal spring environment's clean mountain air generally maintain better conditions than lowland Brazilian cities. Dry season burning from surrounding Minas Gerais agricultural land adds seasonal variation.

When is air pollution at its worst in Poços de Caldas?
Air quality dips in Poços de Caldas mostly track cerrado species and eucalyptus pollen peaks and periods of vehicle emissions from the BR-267 and the surrounding mining and ceramics industry; otherwise, the area's setting generally supports clear, well-ventilated conditions.
Are air quality levels in Poços de Caldas 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.
