Worst air pollution Ansfelden, today and tomorrow

On 20 September 2026, overall air quality in Ansfelden is fair. AQI is the main air quality indicator at 31.5/100. Pollution peaks around 8:00 AM (PM2.5: 31.5/100).

On 21 September 2026, air quality conditions in Ansfelden will be better than today, with AQI forecast at good at 13.2/100. Pollution peaks around 12:00 AM (O3: 13.2/100).

Ansfelden's air quality is at its poorest on still winter mornings, when vehicle traffic and light industry settle under the Alpine foreland's typical inversion pattern. A passing Föhn wind can clear things quickly even in winter, and summer generally sees decent dispersion aside from occasional ozone spikes. Spring and autumn are usually the calmest, cleanest stretches.

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.
