In Arganzuela, construction dust and NO2 from congested streets play the biggest role locally. Air quality is worst during weekday rush hours, especially in winter. Winter temperature inversions are a well-documented cause of poor air quality in the city centre.

When is air pollution at its worst in Arganzuela?
How do the seasons affect air quality in Arganzuela? The year's lowest air quality readings tend to cluster in winter, when high-pressure systems suppress the mixing that would otherwise clear away exhaust and smoke. The transition into spring usually brings cleaner air, as more frequent rain and wind reduce the buildup of local pollution. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. By late autumn, air quality is usually back to more moderate levels, though the first cold snaps can bring an early hint of winter's traffic and heating pollution. Away from the moderating effect of the sea, this area experiences starker seasonal air quality swings than coastal Spain.
Are air quality levels in Arganzuela 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.
