In Grande Île, part of Strasbourg, cross-border industry and river traffic is the main local source, though the Vosges and river valleys shape local wind patterns, which helps limit pollution build-up. Winter typically brings the most polluted stretches, as cold air settles over the valleys and traps industrial and heating emissions, while summer is cleaner but not immune to ozone spikes.

Frequently Asked Questions
Is air quality bad in Grande Île right now?
On 9 August 2026, overall air quality in Grande Île is fair. NO2 is the main pollutant at 22.7/100. Pollution peaks around 12:00 PM (O3: 54.5/100).

When is air pollution at its worst in Grande Île?
Residents of Grande Île in Strasbourg notice the most discomfort when cross-border industry and river traffic overlap with heavy oak and hornbeam pollen; the Vosges and river valleys shape local wind patterns, limiting how long conditions stay poor. Nearby Alsace-Lorraine cereal and vineyard land add a further seasonal factor.
Are air quality levels in Grande Île 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.
