Paper Abstract

Model calculations of the time development of the ontical properties of maritime, urban and rural aerosols growing into fogs are given The calculations are carried out for several different ultimate temperatures and rates of change of temperature which lead to different degrees of supersaturation and conseouent optical properties. Different initial temperatures and relative humidities are examined. In the cases of lowest ultimate temperature the fog development and its optical properties are carried to the point at which a single mode distribution oceanic origin maritime aerosol 'becomes bimodal with a well separated heavy fog distribution. The time development of the aerosol near and through the supersaturation phase is obtained using the non-eouilibriun growth equations. The growth of sample point of each component distribution mode of the aerosol are tracked with time. Extinction coefficients are given for A = 0.55μm, 3.7 μm and 10.7μm.
