Reus' air quality reflects its position in the Tarragona metropolitan area, with vehicle traffic on the AP-7 and the surrounding Tarragona petrochemical complex contributing industrial background emissions alongside local vehicle sources. The Mediterranean sea breezes provide afternoon ventilation, while the Tarragona industrial corridor represents the dominant regional emission source affecting the broader Reus metropolitan air quality background throughout the year.

When is air pollution at its worst in Reus?
How does air quality change throughout the year in Reus? Air quality often reaches its yearly low in the depths of winter, when still, cold air holds local emissions from traffic and heating close to ground level. By spring, air quality usually starts trending upward as the calm winter inversions give way to more unsettled, breezier weather. The heat of summer drives up ozone formation, and dry conditions occasionally bring smoke from regional wildfires into the mix. Air quality usually improves through autumn, as returning rains and cooling temperatures wash out summer's ozone and dust build-up. This Mediterranean location benefits from regular sea breezes, though summer's higher traffic volumes and occasional Saharan dust events can offset that.
Are air quality levels in Reus 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.
