Record #103770:

Comparison of melt energy computations and ablatometer measurements on melting ice and snow / D. Scott Munro.

Title: Comparison of melt energy computations and ablatometer measurements on melting ice and snow / D. Scott Munro.
Author(s): Munro, D. Scott.
Date: 1990.
In: Arctic and Alpine Research. (1990.), Vol. 22(2) (1990)
Abstract: Micrometeorological techniques were used to compute hourly melt energy for ablating ice and snow surfaces on Peyto Glacier, Alberta, Canada. Results were compared with measurements made with electic ablatometers which monitored surface lowering directly. Agreement was excellent for ice and good for snow. Hourly differences between computed and measured values tended to exhibit diurnal pattern wherein ablation lags energy input to surface. Thus, delay in runoff from melting ice and snow is linked to diurnal changes in surface water storage.
