Local PM-10 Levels
Aspen’s PM-10 monitor is collocated with Colorado Department of Public Health and Environment’s PM-10 monitors on Pitkin County’s library roof. This location provides a good indication of the overall PM 10 levels for Aspen. Because the monitors are on the roof of a building, they are not a direct correlation to the air quality people are exposed to when they walk, drive, or work in town. The City encourages people to take personal action for their immediate air quality, such as not idling their vehicle and using zero emission lawn equipment.
