Upper Columbia Basin Network
The Upper Columbia Basin Network Vital Signs Network (UCBN) includes nine national park units with significant natural resources in Idaho, Montana, Oregon, and Washington. Park units include Big Hole National Battlefield (NB), City of Rocks National Reserve (NR), Craters of the Moon National Monument (NM), Hagerman Fossil Beds NM, John Day Fossil Beds NM, Lake Roosevelt National Recreation Area (NRA), Minidoka Internment NM, Nez Perce National Historic Park (NHP), and Whitman Mission National Historic Site (NHS). Except for Craters of the Moon NM, which is a Class I air quality area, all other units are Class II air quality areas. Collectively, these parks include and protect habitat for a variety of plant and animal species over a wide geographic area of the Pacific Northwest.
The Network map below provides information on air quality monitoring. Ozone, sulfur dioxide, dry deposition, and meteorology are collected by the Gaseous Pollutant Monitoring (GPMN) network. 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). 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.
