examine the radioactive properties of clouds containing submicron
soot Particles as impurities. The soot particles are assumed
to be distributed Randomly inside water drops. The refractive
index of this inhomogeneous mixture is evaluated using the mixing
rule for a composite medium. Single and multiple scattering
properties are obtained using, respectively the Mie theory and
the delta-Eddington approximation.
presence of soot enhances the visible light absorption in clouds.
A soot volume fraction of 7 × 10"6 in a model stratus cloud
increases the value of the single scattering co-albedo from
10"7 (the value corresponding to that of pure water) to 10"3.
