Overview and Map of IMPROVE Monitoring SitesIMPROVE Monitoring Program OverviewThe Interagency Monitoring of Protected Visual Environments (IMPROVE) program isa cooperative measurement effort governedby a steering committee composed of representatives from Federal and regional-state organizations. The IMPROVE monitoringprogram was established in 1985 to aid the creation of Federal and State implementation plans forthe protection of visibilityin Class Iareas (156 national parks and wilderness areas) as stipulated in the 1977 amendments to the Clean Air Act.1The objectives of IMPROVE include:(1) establishing current visibility and aerosol conditions inmandatory class I areas; and(2) identifying chemical species and emission sources responsible for existing man-made visibility impairment.The particulate monitoring portion of the IMPROVE program measures the concentration of the fine (PM2.5) particles for mass,optical absorption, major and trace elements, organic and elemental carbon, and nitrate and of PM10particles for mass. Prior to 2000,IMPROVE sites collect two samples per week, on Wednesdayand Saturday. With the implementation of the RegionalHaze RuletheIMPROVE program changed to a 1-in-3 day schedule.1http://vista.cira.colostate.edu/improve/Overview/IMPROVEProgram_files/frame.htm.IMPROVE Monitoring DataThe data for this report was obtained from the websitehttp://views.cira.colostate.edu/web/. The graphs in this report show the PM2.5(fine) mass monitor values from 2006 to 2012at selected IMPROVE monitoring locations.Additional data, such as the chemical composition datain the graph shown below, is also available as thehttp://views.cira.colostate.edu/web/site, using the composition tool.IMPROVENetworkMapState National Parks, Forests and Wilderness Areas(identifier on IMPROVE Network Map)Idaho (and Idaho/Oregon Border)Craters of the Moon (69), Sawtooth National Forest (70), Hells Canyon (77), Starkey (76)MontanaSula Peak WA (71), Cabinet Mountains WA(75), Gate of the Mountains WA (74)NevadaJarbidge Wilderness Area(68),Great Basin (116)UtahBryce Canyon (51), Canyonlands (50), Capitol Reef (52), Zion (49)WyomingBridger Wilderness (65), North AbsarokaWA (67), Yellowstone NP 2 (66)California-Oregon BorderCrater Lake (86), Lava BedsNational Monument (87), LassenVolcanic National Park (90)Oregon/Washington Border Mount Hood (85) , Columbia River Gorge (112)http://vista.cira.colostate.edu/improve/Overview/IMPROVENetworkExp.htm2.
