Gothenburg's air quality is generally good, benefiting from consistent North Sea westerlies and the Göta river estuary providing maritime ventilation. The Port of Gothenburg, Sweden's largest, contributes shipping emissions that elevate NOₓ along the harbour corridor, while vehicle traffic on the E6 and E20 motorways are the primary urban emission sources. Atlantic storms regularly wash the atmosphere clean throughout the year.

When is air pollution at its worst in Gothenburg?
What is the yearly air quality pattern like in Gothenburg? Winter brings the greatest risk of short-lived pollution episodes, usually tied to wood-burning combined with a lack of wind. Spring usually marks a turning point, with more active weather systems reducing how often pollutants can accumulate. Air quality is typically strongest in summer, helped by more wind and sunshine, though still days can occasionally push up ozone levels. By late autumn, the return of heating season and stiller nights start bringing back the kind of conditions seen in winter. Because the season is milder here than further north, these swings tend to be somewhat less extreme.
Are air quality levels in Gothenburg 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.
