Positioned on hills above the Yantra river gorge, Veliko Tŭrnovo experiences air quality shaped chiefly by vehicle traffic and residential wood-burning in the hill town. The Veliko Tarnovo terrain plays a role in how pollutants move through the area, with breezier conditions typically dispersing emissions faster than the still, settled spells that let them accumulate.

When is air pollution at its worst in Veliko Tŭrnovo?
Air quality dips in Veliko Tŭrnovo are most closely tied to oak and hornbeam pollen and spells of vehicle traffic and residential wood-burning in the hill town; the rest of the calendar in Veliko Tarnovo tends to bring steadier, more favourable conditions overall.
Are air quality levels in Veliko Tŭrnovo 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.
