Snow physics as relevant to snow photochemistry [PDF]

Atmospheric Chemistry and Physics, 2008
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 knowledge of snow physical ...

Observations and simulations of new snow density in the drifting snow-dominated environment of Antarctica

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 ...

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

The 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 ...

Ionic Liquid Electrolytes for Extreme Temperature Conditions: Challenges and Perspective

Angewandte Chemie, EarlyView.
Ionic liquids (ILs) have gained great attention as safe electrolyte components in recent years. This review elucidates the temperature effects on IL‐based electrolytes from molecular configurations, physicochemical properties, and interfacial chemistry, raises the challenges and design strategies operating at low‐ and HT, providing valuable guidance ...

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

The 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.

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

Annals 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.

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

The 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 ...

SNOWMIP2: An evaluation of forest snow process simulation [PDF]

, 2009
The Northern Hemisphere has large areas that are forested and seasonally snow covered. Compared with open areas, forest canopies strongly influence interactions between the atmosphere and snow on the ground by sheltering the snow from wind and solar ...

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

Annals 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

Materials & 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 ...
