Las Rozas de Madrid's air quality benefits from its elevated position on the northern Madrid sierra foothills at 778 metres, with vehicle traffic on the A-6 and M-50 motorways contributing local sources in this affluent northwestern Madrid suburb. The Sierra de Guadarrama to the north provides clean mountain airflows, while the elevated position above the main Madrid basin helps avoid the worst winter temperature inversion accumulation that affects central Madrid streets.

When is air pollution at its worst in Las Rozas de Madrid?

What time of year has the cleanest air in Las Rozas de Madrid? Winter tends to bring the year's weakest readings, as stagnant, cold air lets heating smoke and vehicle emissions build up rather than clear away. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. The heat of summer drives up ozone formation, and dry conditions occasionally bring smoke from regional wildfires into the mix. Conditions generally improve through autumn as cooling temperatures reduce ozone formation and returning rains help disperse remaining pollutants. The plateau's continental climate, with cold winters and hot, dry summers, tends to produce more pronounced seasonal differences here.

Are air quality levels in Las Rozas de Madrid 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.
