Worst air pollution Kriens, today and tomorrow

On 30 August 2026, overall air quality in Kriens is fair. AQI is the main air quality indicator at 26.5/100. Pollution peaks around 1:00 PM (O3: 26.5/100).

On 31 August 2026, air quality conditions in Kriens will be similar to today, with AQI forecast at fair at 25.0/100. Pollution peaks around 4:00 PM (O3: 25.0/100).

The worst stretch for air quality at Kriens tends to be a calm winter day, as vehicle traffic and lake-season tourism gather along the lakeshore under a layer of trapped cold air. The rest of the year sees much better conditions around this lake basin, with summer's ozone spikes limited to the hottest, stillest days.

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.
