Js. Rimmer et Cpr. Saunders, EXTINCTION MEASUREMENTS AND SINGLE SCATTERING ALBEDO IN THE 0.5 TO 1.05 MU-M RANGE FOR A LABORATORY CLOUD OF HEXAGONAL ICE CRYSTALS, Atmospheric research, 49(2), 1998, pp. 177-188
Measurements are presented of the extinction coefficients for two labo
ratory-generated clouds of ice crystals, each with different size dist
ributions and concentrations. The shape of the extinction curve for bo
th clouds, over the wavelength range of 0.5-1.05 mu m, is similar to t
hat of the absorption curve for bulk ice. This data has been used to d
etermine the single scattering albedo over the same wavelength range a
nd it is found that the results are significantly different to the gen
erally accepted values. (C) 1998 Elsevier Science B.V. All rights rese
