Air quality conditions in Östersund are usually good, occasionally interrupted by short-lived local spikes. The presence of winter sports and forestry in the area contributes a modest but steady share of local emissions, compounded by traffic on the main routes through town. Air currents around the shores of Lake Storsjön tend to clear pollutants before they can accumulate for long. These combined factors give Östersund air quality that most residents would consider unremarkable in a good way.

When is air pollution at its worst in Östersund?

Does air quality in Östersund 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. Air quality tends to recover through spring as milder, windier conditions replace the still winter air masses. The year's most consistently good air usually falls in summer, when heating season has ended and ventilation improves. Conditions gradually shift through autumn, with cooling temperatures reviving wood-burning and calmer nights allowing brief local build-ups. This seasonal swing is typically more marked here than further south, reflecting the region's longer, colder winter.

Are air quality levels in Östersund 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.
