SHORT TERM CO STUDY Air Monitoring Station, Aspen, Colorado

SHORT TERM CO STUDY is an air monitoring station located at the Aspen City Building in Aspen, Pitkin County, Colorado, United States. The station is operational and focuses on short-term carbon monoxide (CO) monitoring, contributing to the US EPA Air Quality System (AQS) network. As a specialized monitoring site, it provides data on criteria pollutants to support local and regional air quality assessments. The station operates under the regulatory framework of the US Clean Air Act, with data reported by the Colorado Department of Public Health and Environment. While the specific parameters measured are not detailed, short-term CO studies typically involve continuous or integrated sampling to capture peak concentrations. The station's siting in an urban area ensures representativeness for population exposure, though its temporary nature may limit long-term trend analysis. Environmental monitoring in Aspen is critical due to the city's location in a mountain valley, which can trap pollutants from vehicle emissions and wood burning. The SHORT TERM CO STUDY helps assess compliance with National Ambient Air Quality Standards (NAAQS) for CO, protecting public health and supporting air quality management in a region known for its outdoor recreation and tourism.

Aspen, Colorado, is situated in a high-altitude mountain valley, where temperature inversions can trap air pollutants, leading to elevated concentrations of carbon monoxide and particulate matter. The SHORT TERM CO STUDY station provides targeted monitoring to assess local air quality impacts from traffic and residential heating. This data supports the Colorado Department of Public Health and Environment in evaluating compliance with EPA standards and informing public health advisories.
