Project Overview

Furtherance of a national goal that calls for “the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Class I federal areas which impairment results from manmade air pollution.” The Regional Haze Rule (RHR) expanded this mandate by requiring monitoring in locations representative of the 156 visibility-protected federal Class I areas. IMPROVE was designated as the visibility monitoring network to be used to carry out this responsibility.

Objectives

Determine compliance with (PM-10) National Ambient Air Quality Standards. Determine concentrations and composition of fine particles (PM-2.5) of relevance to light scattering, light absorption, human health and biological effects. Data available for use in conjunction with other biological, physical and chemical variables in trend and relationship assessments.
