Modeling the small-scale deposition of snow onto structured Arctic sea ice during a MOSAiC storm using snowBedFoam 1.0. [PDF]

open access: yesGeoscientific Model Development, 2022
The remoteness and extreme conditions of the Arctic make it a very difficult environment to investigate. In these polar regions covered by sea ice, the wind is relatively strong due to the absence of obstructions and redistributes a large part of the ...

A rigorous approach to the specific surface area evolution in snow during temperature gradient metamorphism [PDF]

open access: yesThe Cryosphere
Despite being one of the most fundamental microstructural parameters of snow, the specific surface area (SSA) dynamics during temperature gradient metamorphism (TGM) have so far been addressed only within empirical modeling.

Macroscopic water vapor diffusion is not enhanced in snow [PDF]

open access: yesThe Cryosphere, 2021
Water vapor transport in dry snowpacks plays a significant role for snow metamorphism and the mass and energy balance of snowpacks. The molecular diffusion of water vapor in the interstitial pores is usually considered to be the main or only transport ...

A novel method to visualize liquid distribution in snow: superimposition of MRI and X-ray CT images

open access: yesAnnals of Glaciology
The relationship between the behavior of water in snow and its microstructure is crucial to improve the prediction of wet snow disasters. X-ray computed tomography (X-ray CT) is frequently used to observe snow microscopically.

Reflections on the anomalous ANITA events: the Antarctic subsurface as a possible explanation

open access: yesAnnals of Glaciology, 2020
The Antarctic Impulsive Transient Antenna (ANITA) balloon experiment was designed to detect radio signals initiated by high-energy neutrinos and cosmic ray (CR) air showers.

Using Icepack to reproduce ice mass balance buoy observations in landfast ice: improvements from the mushy-layer thermodynamics [PDF]

open access: yesThe Cryosphere
Icepack (v1.1.0) – the column thermodynamics model of the Community Ice CodE (CICE) version 6 – is used to assess how changing the thermodynamics from the Bitz and Lipscomb (1999) physics (hereafter BL99) to the mushy-layer physics impacts the model ...

A method for imaging water transport in soil–snow systems with neutron radiography

open access: yesAnnals of Glaciology
Liquid water at the ground–snow interface is thought to play a crucial role in the release of glide-snow avalanches, which can be massive and threaten infrastructure in alpine regions.

New approach to moisture accumulation assessment

open access: yesMaterials & Design, 2019
We suggest an innovative approach to simulate moisture buildup on structures with arbitrary geometries and different surface adhesion characteristics. Using 3D particle physics, rain, snow and freezing rain buildup on flat and cylindrical surfaces was ...

Seasonal snow–atmosphere modeling: let's do it [PDF]

open access: yesThe Cryosphere
Mountain snowpack forecasting relies on accurate mass and energy input information in relation to the snowpack. For this reason, coupled snow–atmosphere models, which downscale input fields to the snow model using atmospheric physics, have been developed.

Dye tracing of upward brine migration in snow

open access: yesAnnals of Glaciology
Salt is often present in the snow overlying seasonal sea ice, and has profound thermodynamic and electromagnetic effects. However, its provenance and behaviour within the snow remain uncertain. We describe two investigations tracing upward brine movement
