### IMPROVE Monitoring Program Overview

The Interagency Monitoring of Protected Visual Environments (IMPROVE) 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 visibilit y 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 visibility and aerosol conditions in mandatory 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

(PM 2.5 

### ) particles for mass, optical absorption, major and trace elements, organic and elemental carbon,

and nitrate and of PM 10 

### particles for mass. Prior to 2000, IMPROVE sites collect two samples per

week, on Wednesday and Saturday. With the implementation of the Regional Haze Rule the IMPROVE

program changed to a 1

- in

- 3 day schedule.
