Harstad's sheltered fjord location moderates the strong winds typical further north, so vehicle traffic and winter wood burning have a slightly longer local footprint before maritime airflow clears the town.

When is air pollution at its worst in Harstad?
Locally, Harstad's air is most affected during the peak weeks of the birch pollen season, when the brief summer growing season concentrates pollen into a short, sharp window. The region's overall low population density keeps background air quality high the rest of the time. Otherwise, Harstad maintains good air quality across most of the calendar.
Are air quality levels in Harstad 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.
