Measurements of the air permeability were performed on snow from six horizons within a snowpack at the Glacier Lakes Ecosystems Experiment Site in southeastern Wyoming. The snow was new or equitemperature snow, with densities (&rgr;s) ranging between 0.134 and 0.367 Mg m-3. The specific surface area of ice in each sample was measured stereologically. Intrinsic permeabilities (K0) calculated from these data ranged from 3.0¿10-10 to 3.1¿10-9 m2. The data fitted the equation K0=1.096¿10-8e-9.57&rgr;s, with a standard deviation of 2.8¿10-10 m2. A dimensionally correct relationship between permeability and specific area did not fit our data as well as a simple density relationship. The small scatter reported is attributed to careful selection of undamaged samples and the prevention of sample sublimation during the measurements. ¿ American Geophysical Union 1993
