Cham sits within the Franconian river-valley countryside, where vehicle traffic along the regional road network and surrounding manufacturing and agricultural activity contribute the main local air quality sources. Gently rolling Franconian terrain generally allows moderate dispersal, while regional traffic corridors and the wider Franconian industrial base shape conditions throughout the year.

When is air pollution at its worst in Cham?
Air quality dips in Cham mostly track linden, hornbeam, and beech pollen peaks and warm, stagnant days when local emissions settle; the town's own traffic remains a modest, everyday contributor. From mid-August, a modest ragweed presence typically appears in this warmer region. Conditions generally improve on windier, less humid days.
Are air quality levels in Cham 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.
