Most days in Piteå bring air quality that meets good Swedish and European standards without difficulty. Local sources are dominated by paper and pulp industry and everyday vehicle traffic rather than any single major industrial emitter. Air currents around the Bothnian Bay coastline tend to clear pollutants before they can accumulate for long. The net effect is that Piteå experiences air quality broadly consistent with comparable Swedish towns.

When is air pollution at its worst in Piteå?
How does air quality change throughout the year in Piteå? Midwinter is generally the least favourable period, as still air and cold temperatures allow local pollutants to build up rather than clear. The changeable spring weather generally keeps pollutant levels lower than in winter, even as pollen becomes more relevant. Summer generally brings the year's best air quality, thanks to longer days, more ventilation, and less need for heating. Autumn sees a gradual decline from summer's good conditions, as cooler weather brings back wood-smoke and less consistent wind. Because winters here are longer and colder, the seasonal contrast tends to be sharper than in southern Sweden.
Are air quality levels in Piteå 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.
