Short summary
This work uses terrestrial laser scanning techniques to monitor and quantify changes to snow cornices near Longyearbyen, Svalbard, Norway, with sub-decimeter accuracy. Our findings illustrate how complex interactions between topography and meteorological conditions govern the growth, failure, and associated avalanche activity of the cornices in this location. These findings can help improve forecasting of snow-cornice-related hazards in this and other locations exposed to snow cornice hazards.
