Overview
The Tudor Professional Building air monitoring station in Anchorage, Alaska, is an operational facility managed by the Alaska Department of Environmental Conservation. It provides ambient air quality data as part of the US EPA Air Quality System netw
The Tudor Professional Building air monitoring station is located on the roof of the building at 4335 Laurel Street in Anchorage, Alaska. Operated by the Alaska Department of Environmental Conservation, this station is part of the US EPA's Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). As an air monitoring station, it typically measures pollutants such as PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, along with meteorological parameters like wind speed and direction. The station's location in an urban area provides representative data for population exposure assessment. The most recent sample date is June 30, 2025, indicating ongoing operations. Anchorage's air quality is influenced by local sources including vehicle emissions, residential heating, and industrial activities. This station contributes to the state's air quality management and public health protection by providing continuous data for regulatory compliance and community awareness. The data supports the development of air quality forecasts and informs policy decisions.
Environmental context
Anchorage's air quality is shaped by its subarctic climate, with temperature inversions in winter trapping pollutants near the surface. The Tudor Professional Building station's rooftop siting ensures representative sampling of urban air. Monitoring covers criteria pollutants and meteorological parameters, supporting the EPA's AQS network. This data is critical for assessing compliance with NAAQS and for public health advisories during wildfire events or cold-weather inversions.
