LIGHT SCATTERING CONSTANTS FOR A WATER CLOUD

The study of radiative transfer in clouds and fog requires a knowledge of basic radiation constants. For this purpose the volume extinction, scattering, and absorption coefficients, the maximum absorption coefficients for composite spectral lines, and the coefficients used to expand the phase function into a series of Legendre polynomials for analytic representation of the phase function are provided in tabular and graphical format. The analysis for cloud droplets is based upon the rigorous electromagnetic theory. All Mie computations are carried out in an exact manner avoiding any approximations. Absorption line constants as computed here are based upon the investigations of Elsasser with Culbertson [5]3) and Wyatt, Stull, and Plass [18]. Tabulations are made on the basis of fifty spectral intervals covering the entire solar and infrared spectra. Polarization effects are disregarded in this study. © 1969 Birkhäuser Verlag.
