Surface hoar characteristics derived from a snow micropenetrometer using moving window statistical operations
Lutz, Eric; Birkeland, Karl W.; Kronholm, Kalle; Hansen, Kathy; Aspinall, Richard (Journal article, 2007)This study aims to improve analytical techniques for studying stratigraphic dimensions and hardness characteristics of thin weak layers in the mountain snowpack, with particular interest to buried surface hoar layers. By ... -
Temporal changes in the spatial variability of shear strength and stability.
Logan, Spencer; Birkeland, Karl W.; Kronholm, Kalle; Hansen, Kathy (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)Avalanche forecasting involves the prediction of spatial and temporal variability of the snowpack. To predict avalanches with more accuracy it is important to determine whether the snowpack is becoming more spatially ...
