minimal local traffic in the remote plateau town, combined with Bragança's setting on a plateau near the Spanish border in Trás-os-Montes, largely defines the town's air quality profile within Bragança. Active weather typically improves conditions quickly, whereas extended calm, dry spells tend to let local sources accumulate.

When is air pollution at its worst in Bragança?
People in Bragança tend to notice worse air when cypress and pine pollen peaks, or because of minimal local traffic in the remote plateau town; the remainder of the year in Bragança generally brings clearer, steadier conditions, especially on breezier days that help disperse local emissions across the surrounding countryside and built-up streets alike.
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.
