Resources sensitive to air quality
The Air Resources Division is developing an inventory of air quality related values (AQRVs) for Inventory & Monitoring (I&M) parks. AQRVs are resources that may be adversely affected by a change in air quality. The resource may include visibility or a specific scenic, cultural, physical, biological, ecological, or recreational resource. NPS AQRVs include visibility, vegetation, water quality, soils, and fish and wildlife. The Air Resources Division is also developing air quality monitoring protocols for the networks. The AQRV inventory and available protocols can be accessed from the Inventory Products section below and the I&M Protocol Database.
AQRV inventory products include data, reports, interpretive materials, and maps on air quality issues and concerns in the 48 Class I national parks and 32 I&M networks of national parks
