Alingsås generally enjoys good air quality, in line with most Swedish towns of comparable size. The presence of textile heritage and logistics in the area contributes a modest but steady share of local emissions, compounded by traffic on the main routes through town. The area benefits from air movement associated with the Säveån river and its lakes, which limits how long pollutants linger locally. The net effect is that Alingsås experiences air quality broadly consistent with comparable Swedish towns.

When is air pollution at its worst in Alingsås?
Does air quality in Alingsås vary by season? The darkest winter months tend to bring the year's weakest readings, since calm, cold air allows pollutants from heating and traffic to accumulate rather than disperse. Spring usually marks a turning point, with more active weather systems reducing how often pollutants can accumulate. Summer typically brings the calmest air quality picture, punctuated only rarely by ozone build-up during still, hot weather. Autumn conditions worsen gradually as heating resumes, though not yet to the extent seen during the depths of winter. Given the region's milder winters, the contrast between the seasons here tends to be gentler than in northern Sweden.
Are air quality levels in Alingsås 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.
