Snow physics as relevant to snow photochemistry [PDF]
Atmospheric Chemistry and Physics, 2007 Abstract. Snow on the ground is a complex multiphase photochemical reactor that dramatically modifies the chemical composition of the overlying atmosphere. A quantitative description of the emissions of reactive gases by snow requires the knowledge of snow physical properties.

The Snow-Friction of Freestyle Skis and Snowboards Predicted From Snow Physical Quantities [PDF]
Frontiers in Mechanical Engineering, 2021 Previous research has shown that friction between ski and snow can vary substantially due to changes in snow conditions. The variation of friction affects the speed a freestyle skier or snowboarder (athlete) reaches during the in-run of a jump. Athletes risk severe injuries if their take-off speed is not within the right margin to land in the “sweet ...

Modelling the transition from grain-boundary sliding to power-law creep in dry snow densification
Journal of Glaciology, 2022 This paper presents a physics-based macroscale model for the densification of dry snow which provides for a smooth transition between densification by grain-boundary sliding (stage 1) and densification by power-law creep (stage 2).

Effect of horizontal divergence on estimates of firn-air content
Journal of Glaciology, 2021 Ice-sheet mass-balance estimates derived from repeat satellite-altimetry observations require accurate calculation of spatiotemporal variability in firn-air content (FAC).

Initial snow-ice formation on a laboratory scale
Annals of Glaciology, 2023 Snow ice (SI) forms from freezing wet snow, known as slush, and contributes to the thickness of level and brash ice. However, the mechanism of snow-slush-snow ice transformation has not been extensively investigated to date, despite the difference in the

Improving the snow physics of WEB-DHM and its point evaluation at the SnowMIP sites [PDF]
Hydrology and Earth System Sciences, 2010 In this study, the snow physics of a distributed biosphere hydrological model, referred to as the Water and Energy Budget based Distributed Hydrological Model (WEB-DHM) is significantly improved by incorporating the three-layer physically based energy ...

Comparing measurements of snow mechanical properties relevant for slab avalanche release
Journal of Glaciology, 2019 Snow properties relevant to the fracture processes involved in dry-snow slab avalanche release include weak layer specific fracture energy, slab elastic modulus and density.

Annals of Glaciology, 2018 Full snow-pit observations were performed on a monthly basis over ten winter seasons from 1995 to 2004, at 15 study plots spaced at 100 m elevation intervals (1300–2700 m a.s.l.) in the mountainous forest of the Japanese Central Alps.

Journal of Glaciology, 2023 Owing to drifting snow processes, snow accumulation and surface density in polar environments are variable in space and time. We present new field data of manual measurements, repeat terrestrial laser scanning and snow micro-penetrometry from Dronning ...
