Kremmling Air Monitoring Station | US Forest Service, Colorado

Kremmling is an air monitoring station located in Kremmling, Grand County, Colorado, United States. Operated by the US Forest Service, the station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station's location in a rural, high-altitude setting provides valuable background air quality data for the region. The station reports data to the US Forest Service, with the most recent sample collected on September 30, 2024. While specific parameters measured are not detailed, typical Forest Service monitoring includes ozone, particulate matter, and meteorological variables to assess wildfire impacts and regional haze. The station's siting in a forested area supports representativeness for natural background conditions. Environmental monitoring at Kremmling supports the US Forest Service's mission to protect air resources in national forests and wilderness areas. Data from this station helps track long-term trends in air quality, evaluate the effectiveness of emission reduction policies, and inform land management decisions. The station's operational status ensures continuity of this critical monitoring effort.

Kremmling sits in the Rocky Mountains at an elevation of approximately 7,300 feet, surrounded by national forests and wilderness areas. The region experiences clean continental air masses with occasional influences from wildfires and long-range transport of pollutants. Monitoring here is crucial for understanding background ozone levels, visibility impairment, and deposition of nitrogen and sulfur compounds in sensitive alpine ecosystems. The station's data supports the EPA's AQS network and the Interagency Monitoring of Protected Visual Environments (IMPROVE) program.
