Barcelona's air quality is shaped by the Eixample's dense street canyon geometry and the surrounding sea and mountain topography, with the Collserola hills blocking northwesterly ventilation and the Mediterranean sea breeze providing afternoon relief. Summer ozone and winter NO₂ episodes are the primary recurring air quality concerns across the metropolitan area.
