vehicle traffic in the dense Lisbon metropolitan belt, combined with São Domingos de Rana's setting on the Lisbon coastal plain near Cascais, largely defines the town's air quality profile within Lisboa. 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 São Domingos de Rana?
In São Domingos de Rana, reduced air quality is most noticeable when oak and plane pollen is at its peak, and on days affected by vehicle traffic in the dense Lisbon metropolitan belt; conditions tend to settle down again once weather patterns shift and the local Lisboa terrain ventilates more freely, usually bringing several weeks of steadier readings.
Are air quality levels in São Domingos de Rana 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.
