Asenovgrad's air quality reflects the Maritsa upper valley in the Plovdiv foothills at 185 metres, with vehicle traffic on the E80 and surrounding wine, food processing, and light manufacturing contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the Rhodope Mountains to the south create topographic variation and the flat Thracian plain to the north provides reasonable dispersal on northerly and westerly wind days throughout the year.

When is air pollution at its worst in Asenovgrad?
In Asenovgrad, reduced air quality is most noticeable when oak and plane pollen peaks, and on days affected by vehicle traffic on the E80 and neighbouring wine, food processing, and light manufacturing; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Asenovgrad 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.
