Importance

Both the Clean Air Act and the National Park Service (NPS) Organic Act protect air resources in national parks. Six Northern Colorado Plateau Network (NCPN) parks are designated as Class I areas, which receive the highest protection under the Clean Air Act: Arches, Black Canyon of the Gunnison, Bryce Canyon, Canyonlands, Capitol Reef, and Zion national parks. Understanding changes in air quality can aid in interpreting changes in other monitored vital signs and support evaluation of compliance with legislative and reporting requirements. The NCPN has identified several components of air quality as high-priority vital signs for monitoring. Over the past three decades, the NPS has developed several internal and cooperative programs for monitoring various measures of air quality. The NCPN will acquire and analyze data from existing stations and report on data specific to park units.

Long-term Monitoring

The NCPN acquires, analyzes, and reports on air quality data primarily from the web-based program archives of four ongoing air quality monitoring programs: the Clean Air Status and Trends Network (CASTNET), the National Atmospheric Deposition Program (NADP), the National Park Service–Air Resources Division Gaseous Pollutant Monitoring Program, and the Interagency Monitoring of Protected Visual Environments (IMPROVE) Program.
