Alcobendas' air quality reflects the northern Madrid metropolitan technology corridor, with vehicle traffic on the M-11 and A-1 motorways and surrounding pharmaceutical and technology companies contributing industrial emissions. The Madrid basin's winter temperature inversion affects the northern corridor, while the flat Castilian Meseta north of the city provides some dispersal on northerly wind days.

When is air pollution at its worst in Alcobendas?
What is the yearly air quality pattern like in Alcobendas? Winter mornings are frequently the year's most polluted, as fog and calm conditions trap traffic fumes and smoke from wood stoves close to the ground. By spring, air quality usually starts trending upward as the calm winter inversions give way to more unsettled, breezier weather. High summer temperatures and strong sun exposure drive ozone levels up, occasionally combined with smoke from nearby wildfires during dry spells. The first rains of autumn typically help clear out any lingering summer dust or ozone, setting up milder conditions ahead of winter. Away from the moderating effect of the sea, this area experiences starker seasonal air quality swings than coastal Spain.
Are air quality levels in Alcobendas 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.
