Aspen Yellow Brick Building Air Monitoring Station, Aspen, Colorado

Aspen Yellow Brick Building is an operational air monitoring station located at 215 N. Garmisch in Aspen, Colorado. Operated by the Colorado Department of Public Health and Environment, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). As a fixed-site monitoring station, it typically measures pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide. The station's siting follows EPA guidelines to ensure representativeness of local air quality, often placed in areas with high population density or near emission sources. The last reported sample date is June 8, 2024, indicating ongoing data collection. The station serves the Aspen community by providing critical air quality data that supports public health advisories and regulatory compliance. Its location in Pitkin County, a mountainous region with tourism and winter sports, makes it important for monitoring air quality impacts from traffic and wood burning. The data contributes to regional air quality assessments and helps inform local environmental policies.

Aspen Yellow Brick Building operates in a mountainous region of Colorado, where air quality can be influenced by winter inversions, wildfire smoke, and vehicle emissions from tourism. The station's monitoring of criteria pollutants supports the EPA's NAAQS compliance and provides data for the Colorado Department of Public Health and Environment's air quality reports. Its siting in an urban area ensures representativeness of population exposure, while the network's continuity helps track long-term trends and episodic events.
