Worst air pollution Odense, today and tomorrow

On 4 August 2026, overall air quality in Odense is medium. AQI is the main air quality indicator at 43.2/100. Pollution peaks around 6:00 PM (O3: 43.2/100).

On 5 August 2026, air quality conditions in Odense will be worse than today, with AQI forecast at fair at 34.1/100. Pollution peaks around 11:00 AM (O3: 34.1/100).

Odense's air quality most often suffers along the harbour corridor when the Port of Odense's container and ferry operations are busiest, combined with motorway traffic into the city centre. The flat Funen plain and open water channels generally prevent this from persisting.

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.
