Zadar's air quality benefits from its exceptional Dalmatian coastal position on the Zadar Channel, with consistent Adriatic sea breezes and the powerful Bura wind from the Dinaric Alps providing reliable and often dramatic natural ventilation. Vehicle traffic on the A1 motorway and the ferry port operations contribute local sources, while the outstanding maritime exposure and the Bura wind's frequency generally maintain Zadar among Croatia's cleaner coastal urban environments.

When is air pollution at its worst in Zadar?
The most noticeable dips in Zadar's air quality come when local tree and grass pollen peaks, or because of vehicle traffic on the A1 motorway and the ferry port operations; the months that follow, the local setting keeps things noticeably clearer than average.
Are air quality levels in Zadar 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.
