Sitting at the foot of the Balkan mountains, Montana sees vehicle traffic and residential wood-burning trapped by the terrain as the dominant local influence on air quality, while the surrounding Montana terrain affects how pollutants disperse. Calm, still conditions tend to let levels build here more than in breezier weather, and the local topography around Montana can trap emissions for longer stretches during stable atmospheric periods.

When is air pollution at its worst in Montana?
In Montana, reduced air quality is most noticeable when oak and pine pollen is at its peak, and on days affected by vehicle traffic and residential wood-burning trapped by the terrain; conditions tend to settle down again once weather patterns shift and the local Montana terrain ventilates more freely, usually bringing several weeks of steadier readings.
Are air quality levels in Montana 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.
