Journal of Advances in Modeling Earth SystemsAccurate estimation of snow accumulation and melt is a critical part of decision‐making in snow‐dominated watersheds. In this study, we demonstrate a flexible methodology to couple a detailed snow model, Crocus, separately to two different land surface ...

A casting method using contrast-enhanced diethylphthalate for micro-computed tomography of snow
Journal of Glaciology, 2021 Casting snow is necessary to prevent metamorphism and deformation prior to X-ray micro-computed tomography (μCT) imaging. Current methods are insufficient for large-scale field sampling of snow due to safety considerations associated with the casting ...

Disentangling creep and isothermal metamorphism during snow settlement with X-ray tomography
Journal of Glaciology, 2023 Once fallen, snow settles due to the combined effects of metamorphism and deformation of the ice matrix under gravity. To understand how these coupled processes affect snow evolution, we performed oedometric compression tests and continuously monitored ...

Operational snow-hydrological modeling for Switzerland
Frontiers in Earth Science, 2023 The seasonal evolution of snow cover has significant impacts on the hydrological cycle and microclimate in mountainous regions. However, snow processes also play a crucial role in triggering alpine mass movements and flooding, posing risks to people and ...

Early-stage interaction between settlement and temperature-gradient metamorphism
Journal of Glaciology, 2017 Snow metamorphism and settlement change the microstructure of a snowpack simultaneously. Past experiments investigated snow deformation under isothermal conditions. In nature, temperature gradient metamorphism and settlement often occur together.

On the use of heated needle probes for measuring snow thermal conductivity
Journal of Glaciology, 2022 Heated needle probes provide the most convenient method to measure snow thermal conductivity. Recent studies have suggested that this method underestimates snow thermal conductivity; however the reasons for this discrepancy have not been elucidated.

Response of snowpack to +2°C global warming in Hokkaido, Japan
Journal of Glaciology, 2020 The response of snowpack to a +2°C global warming relative to the present climate was estimated in Hokkaido, Japan, using a physical snowpack model driven by dynamically downscaled (DDS) data, after model evaluation.
