Microstructure-based modelling of snow mechanics: experimental evaluation of the cone penetration test [PDF]
The CryosphereSnow is a complex porous material presenting a variety of microstructural patterns. This microstructure largely controls the mechanical properties of snow, although the relation between the micro and macro properties remains to be better understood ...

Accurate Inversion of High-Resolution Snow Penetrometer Signals for Microstructural and Micromechanical Properties [PDF]
Cold Regions Science and Technology, 2009 Measurements of snow using a high-resolution micropenetrometer can be used to discriminate between different snow types; in lower-density snow the signal is sensitive to microstructure, and micromechanical properties can be estimated.

Snow microstructure on sea ice: Importance for remote sensing applications [PDF]
, 2021 Snow plays a key role in interpreting satellite remote sensing data from both active and passive sensors in the high Arctic and therefore impacts retrieved sea ice variables from these systems ( e.g., sea ice extent, thickness and age).

Revisiting snow settlement with microstructural knowledge [PDF]
The CryosphereSnow settlement under gravity is primarily driven by the slow creep of its ice matrix, which exhibits a viscoplastic behaviour. Knowledge of the viscoplastic properties of snow is thus crucial for understanding and predicting the snowpack seasonal and ...

Using Ultrasonic Waves to Determine the Microstructure of Snow
Frontiers in Earth Science, 2020 Acoustic signals interact with the physical structure of porous media, are particularly sensitive to porosity and tortuosity, and can be used to measure physical properties in a non-destructive manner. Given the fragile nature of freshly fallen snow, non-

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 ...
