Copenhagen's Østerbro records moderate urban air quality, with residential and commercial traffic on Østerbrogade and surrounding streets contributing to baseline NO₂. The neighbourhood's proximity to the Fælledparken park and the Copenhagen harbour corridor provides periodic ventilation improvement on westerly and northerly wind days.

When is air pollution at its worst in Østerbro?
Østerbro's air quality most often suffers along Østerbrogade during rush hour, when local traffic pushes NO₂ above the Copenhagen average. Proximity to Fælledparken and the harbour corridor helps on westerly and northerly wind days, though built-up streets limit this benefit when calm.
Are air quality levels in Østerbro 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.
