Kardzhali's air quality reflects the Arda river valley in the Rhodope Mountains of southern Bulgaria, with vehicle traffic on the E85 and surrounding tobacco farming and hydro-industrial operations contributing local sources. The surrounding Rhodope ridgelines create significant topographic enclosure, while winter residential wood and coal burning generates elevated PM2.5 under frequent valley inversions and summer conditions are considerably better with the highland breezes providing effective natural ventilation throughout the warmer months.

When is air pollution at its worst in Kardzhali?
Residents in Kardzhali are quickest to notice reduced air quality when oak and pine pollen peaks, or due to vehicle traffic on the E85 and nearby tobacco farming and hydro-industrial operations; the rest of the calendar year typically brings clearer, more consistent conditions.
Are air quality levels in Kardzhali 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.
