Worst air pollution Grossglockner High Alpine Road - Zell am See, today and tomorrow

On 9 August 2026, overall air quality in Grossglockner High Alpine Road is fair. AQI is the main air quality indicator at 35.8/100. Pollution peaks around 12:00 PM (O3: 35.8/100).

On 10 August 2026, air quality conditions in Grossglockner High Alpine Road will be similar to today, with AQI forecast at fair at 32.7/100. Pollution peaks around 5:00 PM (O3: 32.7/100).

Grossglockner High Alpine Road sees almost no meaningful dip in air quality year-round, owing to its high, sparsely developed setting. The only modest exception is peak-season seasonal tourist and cable car traffic, which briefly adds a small local bump. Outside those windows, thin mountain air keeps conditions consistently among the best recorded anywhere in the country.

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.
