Observing the effect of morphology on the elastic properties of new snow using a non-contacting laser ultrasound system

Journal of Glaciology
Quantifying micromechanical and microstructural properties of snow is crucial, as they control bulk thermal, electrical and mechanical properties.

Simulation of Arctic snow microwave emission in surface-sensitive atmosphere channels [PDF]

The Cryosphere
Accurate simulations of snow emission in surface-sensitive microwave channels are needed to separate snow from atmospheric information essential for numerical weather prediction.

Development of a handheld integrating sphere snow grain sizer (HISSGraS)

Annals of Glaciology
We developed a Handheld Integrating Sphere Snow Grain Sizer (HISSGraS) for field use to measure the specific surface area (SSA) of snow. In addition to snow samples, HISSGraS can directly measure snow surfaces and snow pit walls.

Wet Granular Materials

, 2006
Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many ...

Analysis of QualitySpec Trek Reflectance from Vertical Profiles of Taiga Snowpack

Geosciences, 2018
Snow microstructure is an important factor for microwave and optical remote sensing of snow. One parameter used to describe it is the specific surface area (SSA), which is defined as the surface-area-to-mass ratio of snow grains.

Tower-based C-band radar measurements of an alpine snowpack [PDF]

The Cryosphere
To better understand the interactions between C-band radar waves and snow, a tower-based experiment was set up in the Idaho Rocky Mountains for the period of 2021–2023.

Investigating microstructural variation in the human hippocampus using non-negative matrix factorization

, 2019
In this work we use non-negative matrix factorization to identify patterns of microstructural variance in the human hippocampus. We utilize high-resolution structural and diffusion magnetic resonance imaging data from the Human Connectome Project to ...

Retrieval of Effective Correlation Length and Snow Water Equivalent from Radar and Passive Microwave Measurements

Remote Sensing, 2018
Current methods for retrieving SWE (snow water equivalent) from space rely on passive microwave sensors. Observations are limited by poor spatial resolution, ambiguities related to separation of snow microstructural properties from the total snow mass ...

Numerical simulation of elastic stress in the microstructure of snow [PDF]

Annals of Glaciology, 2004
AbstractThe mechanical properties of snow depend on its microstructure. The fabric of snow was reconstructed in three dimensions using serial sections or X-ray microtomography. A voxel-based finite-element model, with the elements based on the microstructure and ice as the material, was used to calculate the stress distribution in the snow.
