Colmar's air quality reflects the Alsatian Rhine plain position between the Vosges and the Black Forest, with vehicle traffic on the A35 motorway and surrounding wine and manufacturing industry contributing local sources. The Vosges to the west and the Black Forest to the east create partial topographic enclosure, while the Rhine valley provides the primary ventilation corridor on westerly winds and the flat Alsatian plain generally allows reasonable dispersal on most days throughout the year.

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.
