Abstract

Similarity theory and dimensional analysis are applied to the construction of a relationship for the spectral aerosol extinction coefficient in the visible atmospheric window 0.48 (DOT) 10^-4 cm < (lambda) < 0.76 (DOT) 10^-4 cm. For maritime mist the results allow one to compare the dependence of the spectral extinction coefficient on humidity as determined in situ with known laboratory observations on the variation in the radius of aerosol particle in moist air. Raoult's modified law is used to show that the variation in the optical properties of soluble aerosol is entirely determined by the variation in the average radius of particles depending on humidity.
