For more information about National Park Service air resources,
please visit http://www.nature.nps.gov/air/. 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 -
