Snow as a driving factor of rock surface temperatures in steep rough rock walls

Haberkorn, Anna ; Hoelzle, Martin ; Phillips, Marcia ; Kenner, Robert

In: Cold Regions Science and Technology, 2015, vol. 118, p. 64–75

Observations show that considerable amounts of snow can accumulate in steep, rough rock walls. The heterogeneously distributed snow cover significantly affects the surface energy balance and hence the thermal regime of the rock walls.To assess the small-scale variability of snow depth and rock temperatures in steep north and south facing rock walls, a spatially distributed multi-method approach...
