Short summary
The focus of this paper was to use gas-phase tracers and aerosol composition to characterize the influence of the different sources on optical extinction (RH = 22 %) and summertime visibility in the Colorado Front Range. Our analysis indicates that aerosol nitrate contributed significantly to optical extinction in agriculturally influenced air masses, while in other plumes, organics could explain most of the observed variability in optical extinction.
