Bragança's air quality in Pará reflects Atlantic trade winds providing reasonable coastal ventilation, while dry season burning from surrounding Pará Amazon deforestation generates intense PM2.5 episodes between July and November that dominate the regional air quality across the broader northeastern Amazon corridor.

When is air pollution at its worst in Bragança?
Residents in Bragança are most likely to notice reduced air quality when mangrove vegetation and native Amazon forest remnants pollen peaks, or due to surrounding Pará Amazon deforestation; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Bragança 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.
