Hohenems' air quality reflects its Rhine valley position in central Vorarlberg, with vehicle traffic on regional roads the primary local source. The broad valley floor generally allows reasonable wind dispersal.

When is air pollution at its worst in Hohenems?
The poorest air quality at Hohenems tends to occur during still winter spells, as vehicle traffic and cross-border commuting linger before onshore breezes off the Bodensee return. Conditions generally improve through spring and summer, aside from occasional ozone spikes during prolonged heat. Autumn is typically calm and comparatively clean thanks to the lake's moderating effect.
Are air quality levels in Hohenems based on measurements or forecasts?
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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
