In Barajas, heavy road traffic and NO2 from congested streets play the biggest role locally. Air quality is worst during weekday rush hours, especially in winter. The urban heat-island effect can trap traffic pollution close to street level on calm days.

When is air pollution at its worst in Barajas?
How do the seasons affect air quality in Barajas? December through February is often the toughest stretch, driven by temperature inversions that keep exhaust and heating smoke from dispersing on still days. March through May tends to see steady improvement, with more unsettled weather patterns helping disperse traffic and heating pollution. Summer's intense heat and sunshine create ideal conditions for ozone formation, sometimes overshadowing the lower traffic volumes typical of the season. Autumn generally marks the shift back toward calmer, cleaner conditions as temperatures drop and rainfall becomes more regular. The interior's dry continental climate means winter inversions and summer heat both tend to hit harder than along the coast.
Are air quality levels in Barajas 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.
