Abstract

Measurements of light scattering and the chemical composition of the fine aerosol from the Portland (Oregon) Aerosol Characterization Study (PACS) of 1977-1978 are reported. Scattering coefficients for sulfate, nitrate, carbonaceous aerosol and residual mass were determined by stepwise multiple linear regression. Unlike other cities the scattering efficiencies for sulfate, nitrate and carbonaceous aerosol were approximately the same. Carbonaceous aerosol was found to account for about 50% of both the fine aerosol mass and the light scattering.
