Arches National Park Air Quality Monitoring
Air Atlas is a GIS database of air quality estimates for 270 parks that are part of the NPS Inventory and Monitoring Program. These estimates can be used when on-site monitoring data is not available. Air Atlas
Atmospheric Deposition Monitoring
Information from wet (i.e., rain, snow) and dry (i.e., dust, dryfall) deposition samplers at Canyonlands NP can be used to characterize conditions in Arches NP. Wet deposition is monitored in Canyonlands NP (1997-present) as part of the National Atmospheric Deposition Program/National Trends Network (NADP/NTN). The site ID is UT09. Dry deposition rates are estimated for Canyonlands NP (site CAN407), 1995-present, as part of the Clean Air Status and Trends Networks (CASTNet).

Optical monitoring to collect baseline data on night sky brightness has been completed at Arches NP. The optical measurement produces, not only a measure of night sky brightness and identification of light pollution sources, but also produces a measure of the effect of the atmosphere on light scattering caused by fine particulates and other air pollutants, and moisture.
Tropospheric (ground-level) ozone concentrations were monitored in Arches NP from 1987-1992. Current conditions can be characterized using information from the ozone monitor in Canyonlands NP (1992-present) because of its relative proximity to Arches NP. Ozone concentrations and cumulative doses have also been estimated for Arches NP as part of the Air Atlas project (Air Resources Division).
As part of the Interagency Monitoring of Protected Visual Environments (IMPROVE) network, visual air quality in Arches NP has been monitored using an aerosol sampler (1988-1992) and 35mm camera (1986-1991). At present, information from visibility monitors in Canyonlands NP (35 km south of Arches NP) is used to characterize conditions in Arches, because of the relative proximity of the two parks. Visual air quality in Canyonlands NP has been monitored using an aerosol sampler (1988-present), a transmissometer (1986-present), and a 35mm camera (1982-1995).
