Abstract

At nine sites on Andrei Glacier, B.C., albedo measurements were carried out on ice surfaces which were contaminated to varying degrees. Four albedo classes were derived in terms of the amount of aeolian dirt that was deposited on the ice surface. Each albedo class was associated with one of the 'white', 'whitish', 'dirty' or 'very dirty' surfaces, and each class had signigicantly different albedos, the means of which ranged from 22% to 68%. Values in each albedo group were normally distributed over time. Albedos from wet ice surfaces were found between the -2 and -3 standard deviation band of each albedo class distribution. Albedo values measured on freshly frozen ice surfaces tended to occupy the upper tail of the Gaussian normal distribution, i.e., between +2 and +3 standard deviations. Albedo values have been tabulated and plotted along a grid of 500-m mesh. Finally, suggestions are given on how to model hourly ice surface albedo distribution over the glacier
