摘要：

The literature on the absorption coefficient and reflectivity of water and ice in the infrared is critically reviewed, and best values are chosen for the complex index of refraction for wavelengths 0.7 μ ≤ λ ≤ 200 μ. The Mie theory is then used to compute the single scattering albedo a, asymmetry factor 〈 cos θ〉, and normalized extinction cross section Qext for spheres of water and ice with radii 0.3, 1.0, 3.0, and 10.0 microns in this wavelength interval. Significant differences in the absorption spectrum between water and ice and among particles of different radii are illustrated. A useful approximate formula for a is given. The results are important for the study of radiative transfer in planetary cloud layers. © 1968.
