Description: | Special Report Abstract: Arctic fog droplets were sampled on chloride-sensitive gelatin-coated glass slides at Point Barrow, Alaska, in the summer of 1971. The collection efficiency of the fog droplets was determined. About 20,000 fog drop radii were measured. The results of analysis of the concentration and the size distribution of fog drops are presented in the form of tables and photomicrographs. It is shown that the concentration and the size distribution changed rapidly with time and space; the drop radii ranged widely between 3.3 and 65 μ; the mean radius was 10 μ; the maximum concentration was 24 drops/cm^3 and the liquid water content was 0.09 g/m^3 at a visibility of 250m. Calculations were made of the attenuation by fog at wavelengths of 0.571 and 1.06 μ for the observed size distributions and concentrations of fog drops. |
