### IMPROVE Monitoring Program Overview The Interagency Monitoring of Prot ected Visual Environments (IMP ROVE) program is a cooperative measurement effort governed by a steering committee composed of representatives from Federal and regional-state organizations. The IMPROVE monitoring program was established in 1985 to aid the creation of Federal and State implementation plans for the protection of visibili ty in Class I areas (156 national parks and wilderness areas) as stipulated in the 1977 amendments to the Clean Air Act. The objectives of IMPROVE include: (1) establishing current visibili ty and aerosol conditions in mandatory class I areas; and (2) identifying chemical species and emission sources responsible for existi ng man-made visibility impairment.

### The particulate monitoring portion of the IMPROVE pr ogram measures the conc entration of the fine (PM 2.5 

### ) particles for mass, optical absorption, major a nd trace elements, organic and elemental carbon, and nitrate and of PM 10 

### particles for mass. Prior to 2000, IM PROVE sites collect two samples per week, on Wednesday and Saturday. With the impl ementation of the Regional Haze Rule the IMPROVE program changed to a 1-in-3 day schedule. http://vista.cira.colostate.e du/improve/Overview/Overview.htm1
