Abstract : The coefficients of scattering, attenuation, and absorption of 0.8, 1.35, 1.6, 2.5, 3.2, 4, 5.6, and 8.5 cm waves by individual water drops of various size (up to 6.6 mm) at temperatures of -10, 0, 10, and 20C were measured. Also given are data on the polydisperse scattering and attenuation coefficients in precipitation particles of various concentrations. Earlier results of these and other authors are refined, extended, and reported in the form of curves and extensive tables. The dependence of the coefficients on particle size, temperature, and wavelength is pointed out. (Author)
