Salzburg's air quality faces Austria's most distinctive combination of cultural and topographic air quality challenges, with the historic city's enclosed position in the Salzach valley between the Mönchsberg, Festungsberg, and the surrounding Salzburg Alps creating a natural pollution trap. Vehicle traffic on the A1 and A10 motorways and winter residential wood burning generate elevated PM2.5 under frequent winter inversions, while the Alpine Föhn wind periodically delivers exceptional clean mountain air from the south.

When is air pollution at its worst in Salzburg?
At Salzburg, air quality dips most on windless winter days, when vehicle traffic and tourism linger under the kind of inversion common to enclosed Alpine basins. Summer's stronger airflow generally clears the valley well, though hot spells can briefly raise ozone. Spring and autumn are usually the steadiest, cleanest months overall.
Are air quality levels in Salzburg 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.
