Sundbyberg generally enjoys good air quality, in line with most Swedish towns of comparable size. Beyond routine traffic, dense urban residential development is the main local factor influencing emission levels here. Wind patterns linked to the Mälaren inlet at Ulvsundasjön usually keep the air moving enough to prevent prolonged pollution build-up. The net effect is that Sundbyberg experiences air quality broadly consistent with comparable Swedish towns.

When is air pollution at its worst in Sundbyberg?

What is the yearly air quality pattern like in Sundbyberg? Expect the occasional poor-air-quality day in winter, when a stable, windless cold snap traps smoke and exhaust that would otherwise disperse. From spring onward, increasing wind and precipitation generally break up the stagnant conditions that caused winter dips. Summer generally brings the year's best air quality, thanks to longer days, more ventilation, and less need for heating. Autumn generally marks the year's decline back toward winter conditions, driven mainly by the return of wood-burning and stiller air. As is typical for this part of the country, the seasonal contrast here is clear but not extreme.

Are air quality levels in Sundbyberg 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.
