Summary
The present study deals with the approximate scattering characteristics of optically thin cirrus clouds which are known to exist in the vicinity of the tropopause. The assumed homogeneous ice model cloud is composed of randomly oriented circular cylinders of uniform size. The spectral region investigated extends from 0.6–0.7 μ, where absorption by ice and atmospheric gases is negligible Radiative upward and downward intensities are calculated for a uniform ground albedo of 0 and 0.25 using the assumption that multiple-scattering can be disregarded. A rough comparison with the Rayleigh scattering characteristics in this spectral region indicates that remote sensing of the atmosphere is affected very little by the presence of optically thin cirrus assuming the validity of the above assumptions.
