Tvedestrand's narrow, sheltered harbour inlet can see calmer air than the open coast nearby, though regular sea breezes generally prevent local emissions from building up.

When is air pollution at its worst in Tvedestrand?

Tvedestrand residents are most likely to notice reduced air quality when wood-smoke and still air combine in winter, when still, high-pressure days let local emissions settle over the sheltered coastline. The mild coastal climate usually clears these episodes within a day or two. Otherwise, Tvedestrand maintains good air quality across most of the calendar.

Are air quality levels in Tvedestrand 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.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
