Örebro's air quality is generally good, with Lake Hjälmaren's consistent breezes and clean Baltic airflows providing reliable ventilation. Vehicle traffic on the E18 and E20 motorways are the primary local sources, while the surrounding Swedish forest landscape and Baltic weather systems maintain Örebro among Sweden's more moderate urban environments.

When is air pollution at its worst in Örebro?
When is air quality typically worst in Örebro? Cold, still winter days are when pollutant levels are most likely to climb, mainly from heating and traffic rather than any single major source. Air quality tends to recover through spring as milder, windier conditions replace the still winter air masses. Warm-season conditions are generally the most favourable of the year, with wood-burning emissions largely absent. Autumn conditions worsen gradually as heating resumes, though not yet to the extent seen during the depths of winter. As is typical for this part of the country, the seasonal contrast here is clear but not extreme.
Are air quality levels in Örebro 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.
