Variation of the surface snow density with time in the top few centimeters of snow cover was parameterized on the basis of viscous compression theory. A compactive viscous factor is expressed as a function of the snow density and of the mean air temperature. The results show that the snow density increases with time after the last snowfall and that the rate of in-crease for high air temperature cases is greater than that for low air temperature cases. Good. agreement (within±0.05 g cm-3) was found between the calculated snow density and the observed one.
