Klamath Network


The Klamath Vital Signs Network (KLMN) consists of six NPS units. Four out of the six parks in the Klamath Network are designated as Class I air quality areas, receiving the highest protection under the Clean Air Act. Crater Lake National Park (NP), Redwoods NP, Lava Beds National Monument (NM) , and Lassen Volcanic NP are all Class I areas. Oregon Caves NM and Whiskeytown National Recreation Area (NRA) are Class II air quality areas, which also receive protection under the Act, but to a lesser degree.

Four parks in the network have air quality monitoring stations: Crater Lake NP, Lassen Volcanic NP, Lava Beds NM, and Redwood NP. A risk assessment for Klamath Network indicates that the risk for ozone injury is high at Whiskeytown NRA, moderate at Crater Lake NP, Lava Beds NM, Oregon Caves NM, and Redwood NP, and low at Lassen Volcanic NP.

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. Class I areas have linkable access to ARIS information.
