Cumberland Piedmont Network
The Cumberland Piedmont Vital Signs Network (CUPN) consists of fourteen NPS units in Alabama, Georgia, Tennessee, Kentucky, South Carolina and North Carolina. The parks include cultural, historical and natural areas. Mammoth Cave National Park (NP) is a designated Class I air quality area; the rest of the parks are Class II areas.
Mammoth Cave NP and Cowpens National Battlefield have on-site ambient air quality monitoring; in most cases, the other parks have nearby monitors. Ozone is the pollutant of greatest concern for CUPN parks. Five of the Network parks are in proposed 8-hour ozone non-attainment areas. An ozone injury risk assessment indicates the risk of injury is moderate to high in 13 of the 14 network parks; the risk of injury is low at Ninety-Six National Historic Site.
The Network map below provides information on air quality monitoring. Ozone, sulfur dioxide, dry deposition, and meteorology are collected by the Clean Air Status and Trends (CASTNet) and Gaseous Pollutant Monitoring (GPMN) networks. Ozone is also monitored with passive samplers and portable continuous analyzers. Wet Deposition is monitored through cooperation with National Atmospheric Deposition Program/National Trends Network (NADP/NTN). The Mercury Deposition Network (MDN), part of NADP, collects precipitation samples that are analyzed for mercury. Visibility is monitored as part of the Interagency Monitoring of Protected Visual Environments (IMPROVE). Additional details on these parameters are described in Air Quality Monitoring.
Air quality monitoring in or near the network is indicated on the map by symbols, with the blue line showing the approximate borders of the network. The legend shows the symbols for the type of monitoring present, with NPS park units in green. The Class I area has linkable access to ARIS information.
