Ioánnina's air quality faces significant winter challenges in the enclosed Ioannina basin surrounded by the Pindus mountain ranges and Lake Pamvotis, with residential wood and coal burning generating some of northwestern Greece's highest seasonal PM2.5 concentrations under frequent winter temperature inversions. Vehicle traffic on the A2 Egnatia Odos motorway contributes locally, while summer conditions are considerably better with mountain breezes providing effective ventilation.

When is air pollution at its worst in Ioánnina?
People in Ioánnina tend to notice reduced air quality when oak and linden pollen peaks, or because of residential wood and coal burning; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Ioánnina 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.
