Barcarena's air quality faces significant industrial challenges from the Alunorte alumina refinery and Albras aluminium smelter generating elevated fluoride and PM2.5 in one of Brazil's most concentrated heavy industrial zones. The Marajó Bay estuary provides limited maritime ventilation, while the industrial complex's scale makes Barcarena one of the Amazon region's most impacted municipalities.

When is air pollution at its worst in Barcarena?
Reduced air quality in Barcarena is most likely when mangrove vegetation and várzea floodplain species pollen peaks, alongside periods of the Alunorte alumina refinery and Albras aluminium smelter; things typically settle down again once the weather pattern shifts.
Are air quality levels in Barcarena 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.
