Trutnov owes much of its air quality variation to vehicle traffic and tourism in the mountain gateway town, compounded by its position at the foot of the Giant Mountains. The surrounding Hradec Králové Region terrain can either help disperse or trap these emissions depending on the weather, with active, breezy conditions generally bringing the clearest air.

When is air pollution at its worst in Trutnov?
Trutnov sees its worst air quality stretches line up with birch and beech pollen peaks and periods of vehicle traffic and tourism in the mountain gateway town; outside of those windows, the Hradec Králové Region area generally settles into calmer, more breathable conditions.
Are air quality levels in Trutnov 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.
