Abstract The paper analyzes the results of the California 1972-73 Aerosol Characterization Experiment. The determination of the relative contributions of pollution sources is based on the chemical element balance and is independent of the wind field. Coagulation, growth, and sedimentation depend on the time history of the aerosol; the visibility depends on the total volume of material condensed from the gas phase. Materials include sulfates, nitrates, organics, and ammonia, with associated water. Improving visibility during pollution will require a major reduction in aerosol precursor gases.
