Worst air pollution Traun, today and tomorrow

On 9 August 2026, overall air quality in Traun is medium. AQI is the main air quality indicator at 45.6/100. Pollution peaks around 5:00 PM (O3: 45.6/100).

On 10 August 2026, air quality conditions in Traun will be similar to today, with AQI forecast at medium at 50.0/100. Pollution peaks around 12:00 PM (O3: 50.0/100).

Air quality at Traun is usually worst on calm winter mornings, when vehicle traffic and light industry settle under a temperature inversion typical of the Alpine foreland. Summer generally brings better ventilation, occasionally interrupted by the Alpine Föhn wind clearing the air entirely, though hot spells can raise ozone. Spring and autumn tend to be the steadiest.

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.

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.
