Given its setting at the foot of the Ore Mountains, Chomutov's air quality is largely a function of former coal-mining legacy emissions trapped by the terrain, moderated by the broader Ústí nad Labem Region weather patterns. Emissions tend to build during calm, high-pressure spells and clear more readily once winds or rain move through.

Are air quality levels in Chomutov 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.
