Liberec's air quality reflects the Ještěd ridge valley in the Jizera Mountains foothills of northern Bohemia, with vehicle traffic on the R35 expressway and surrounding glass and textile manufacturing contributing local sources. The valley's partial topographic enclosure between the Jizera and Lusatian mountains creates concentration under winter inversions, while Czech-German-Polish border cross-regional pollution transport influences the broader regional background.
