Other objectives are: establish baseline data and trends of fine particulate concentrations; determine the relationship between visibility impairment and various atmospheric particulate constituents; determine the existing sources of particles producing visibility impairment; determine the sensitivity of visibility impairment at individual sites to varying concentrations of particles.

Findings and Status: Seasonal summaries for Fall and Winter 1990; and Spring, Summer, Fall, and Winter 1991 will be sent to the site operator in a seperate mailing.
