ITEP Flagstaff Air Monitoring Station, Flagstaff, Arizona | USA

ITEP Flagstaff is an air monitoring station located on Skyline Drive in Flagstaff, Arizona, within Coconino County. Operated by Tribal Air Monitoring Support - Northern Arizona University, this facility contributes to the US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters across the United States. The station operates under the regulatory framework of the Clean Air Act and EPA ambient air quality standards. While specific parameters measured are not detailed, typical air monitoring stations in this network track pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The station's last reported sample date is June 17, 2020, indicating ongoing data collection. Located in the high-altitude environment of northern Arizona, ITEP Flagstaff provides valuable air quality data for the Flagstaff urban area and surrounding region. This monitoring supports public health assessments, regulatory compliance, and research into local air quality trends, particularly relevant given the area's seasonal wildfire smoke and winter inversions.

Flagstaff sits at approximately 7,000 feet elevation in the San Francisco Peaks region, with air quality influenced by local urban emissions, seasonal wildfire smoke, and winter temperature inversions. The ITEP Flagstaff station's siting is representative of a mixed residential and wildland-urban interface area. Monitoring data from this station supports the EPA's National Ambient Air Quality Standards (NAAQS) compliance tracking and provides critical information for understanding regional air quality dynamics in the Colorado Plateau.
