When is air pollution at its worst in Gamla Stan?

How does air quality change throughout the year in Gamla Stan? The coldest months bring the year's more frequent air quality dips, mostly linked to wood-burning stoves and traffic on still winter days. Spring typically sees fewer stagnant-air episodes, as more frequent wind and rain help disperse local emissions. Summer generally brings the year's best air quality, thanks to longer days, more ventilation, and less need for heating. Conditions gradually shift through autumn, with cooling temperatures reviving wood-burning and calmer nights allowing brief local build-ups. As is typical for this part of the country, the seasonal contrast here is clear but not extreme.

Are air quality levels in Gamla Stan 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.
