Worst air pollution Rankweil, today and tomorrow

On 9 August 2026, overall air quality in Rankweil is fair. O3 is the main pollutant at 39.8/100. Pollution peaks around 2:00 AM (NO2: 43.3/100).

On 10 August 2026, air quality conditions in Rankweil will be similar to today, with O3 forecast at fair at 35.3/100. Pollution peaks around 10:00 PM (NO2: 43.1/100).

At Rankweil, winter mornings bring the worst air quality, when vehicle traffic and cross-border commuting build up under a Rhine valley inversion. Bodensee breezes provide fairly reliable ventilation most of the year, though hot summer spells can briefly push ozone higher. Spring and autumn are usually the most consistently favourable seasons for clean air.

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.
