Uppsala's air quality is excellent by European standards, benefiting from consistent Baltic and Atlantic airflows providing clean maritime ventilation across this major Swedish university city north of Stockholm. Vehicle traffic on the E4 motorway and the surrounding pharmaceutical and biotechnology manufacturing — including AstraZeneca facilities — contribute the primary local sources, while wood-burning stoves add seasonal winter PM2.5, and the flat Uppsala plain and consistent northerly airflows generally maintain Uppsala among Sweden's cleaner major urban environments throughout most of the year.

When is air pollution at its worst in Uppsala?
How does air quality change throughout the year in Uppsala? Cold, still winter days are when pollutant levels are most likely to climb, mainly from heating and traffic rather than any single major source. Spring's changeable weather tends to prevent the kind of stagnant air that causes winter pollution episodes. The year's most consistently good air usually falls in summer, when heating season has ended and ventilation improves. By October and November, cooling air and calmer evenings start to mirror the patterns that intensify further in winter. This is a fairly standard seasonal pattern for central Sweden, with a well-defined winter and summer.
Are air quality levels in Uppsala 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.
