Abstract
During the 1969 field season, a micro-meteorological site was established on Peyto Glacier, and continuous measurement of the shortwave components of the radiation balance became an integral part of this project. In particular, one problem to investigate was the relationship between global radiation and surface ablation of the ice. A correlation analysis showed no significant relationship between these two variables. This can be explained because global radiation is only part of the radiation balance (and only a part of one term in the energy balance equation). Even the inclusion of the shadow effect results in a negligible change in the correlations. The present work is an initial study into the distribution of global radiation over Peyto Glacier, and its relationship to ablation. There is a significant difference in the received solar radiation for any area depending upon its slope, azimuth, and perhaps shadow conditions, but these differences alone do not dictate any statistically meaningful relationship between the two variables. More information is required about the other radiation and energy balance components, both at a point and in a spatial context.
