Tartu's air quality is generally good by European standards, benefiting from the flat Estonian lowland and consistent Baltic and North Atlantic airflows providing reliable ventilation. Vehicle traffic on the E264 and wood-burning stoves during the long cold winters are the primary local sources, while the surrounding boreal forest and Estonian lake district maintain moderate air quality levels throughout most of the year.

When is air pollution at its worst in Tartu?

Air quality dips in Tartu mostly track local combined tree and grass pollen peaks and periods of vehicle traffic on the E264 and wood-burning stoves during the long cold winters; the picture usually improves again once the season turns.

Are air quality levels in Tartu 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.
