Linz's air quality faces Austria's most persistent industrial challenge, with the voestalpine steelworks on the Danube generating significant PM2.5, SO₂, and heavy metals alongside vehicle traffic on the A1 motorway and the Linz urban road network. The Danube valley's topographic enclosure between the Böhmerwald to the north and the Alpine foothills to the south creates concentration of industrial and vehicle emissions under winter temperature inversions, making Linz consistently Austria's most industrially impacted urban air quality environment.

Frequently Asked Questions
Is air quality bad in Linz right now?
On 30 August 2026, overall air quality in Linz is moderate. AQI is the main air quality indicator at 41.2/100. Pollution peaks around 7:00 AM (NO2: 41.2/100).
Will air quality be worse tomorrow in Linz?
On 31 August 2026, air quality conditions in Linz will be better than today, with AQI forecast at fair at 35.5/100. Pollution peaks around 5:00 AM (NO2: 35.5/100).
When is air pollution at its worst in Linz?
The poorest air quality at Linz tends to occur during still winter conditions, when vehicle traffic and light industry linger close to the ground before winds return. Occasional Föhn events can dramatically improve conditions even in winter, while summer sees generally good dispersion aside from the odd ozone spike. Spring and autumn are usually comfortably mild.
Are air quality levels in Linz 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
