in
Class I Areas
through the exchange of
Data, Tools, and Ideas
The
Visibility Information Exchange Web System (VIEWS)
is an online exchange of air quality data, research, and ideas designed to understand the effects of air pollution on visibility and to support the Regional Haze Rule enacted by the U.S. Environmental Protection Agency (EPA) to reduce regional haze and improve visibility in national parks and wilderness areas.

Regional Haze SIP Writers
▪
State and Tribal Implementation Plan (SIP/TIP) writers can find IMPROVE monitoring data products catered to Regional Haze Rule (RHR) planning in the VIEWS
Annual Summary
. Specific products such as 2000-2004 baseline values, natural conditions estimates, and glide slopes are available on the Annual Summary
Trends
page. Please feel free to
contact us
with questions/comments regarding these tools!
▪
Note to SIP writers regarding the new IMPROVE algorithm and natural condition estimates; currently natural condition estimates are only available from VIEWS as calculated by the old IMPROVE algorithm. Application of the new IMPROVE algorithm to natural visibility estimates is currently under review by the RPO Monitoring and Data analysis work group (see the 6/12/2006 presentation below).
What's New:
