Snow stratigraphic heterogeneity within ground-based passive microwave radiometer footprints: implications for emission modeling [PDF]

open access: yes, 2014
Two-dimensional measurements of snowpack properties (stratigraphic layering, density, grain size and temperature) were used as inputs to the multi-layer Helsinki University of Technology (HUT) microwave emission model at a centimeter-scale horizontal ...

Early-stage interaction between settlement and temperature-gradient metamorphism

open access: yesJournal 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.

Review article: Global monitoring of snow water equivalent using high-frequency radar remote sensing [PDF]

open access: yesThe Cryosphere, 2022
Seasonal snow cover is the largest single component of the cryosphere in areal extent, covering an average of 46 × 106 km2 of Earth's surface (31 % of the land area) each year, and is thus an important expression and driver of the Earth's climate.

Tomography-based monitoring of isothermal snow metamorphism under advective conditions [PDF]

open access: yesThe Cryosphere, 2015
Time-lapse X-ray microtomography was used to investigate the structural dynamics of isothermal snow metamorphism exposed to an advective airflow. The effect of diffusion and advection across the snow pores on the snow microstructure were analysed in ...

EVOLUTIONARY CONCEPTION OF SNOW METAMORPHISM BASED ON CRYSTAL-MORPHOLOGY AND THEORY OF SYMMETRY

open access: yesЛëд и снег, 2015
The paper presents a novel approach to the study of development of microstructures in snowpack based on the crystal-morphology and on the fundamental laws of natural symmetry.

Spectral reflectance behavior of different boreal snow types

open access: yesJournal of Glaciology, 2019
Spectral reflectance of natural snow samples representing various stratigraphies was investigated in a controlled dark laboratory environment. Mean and Std dev.

Snow metamorphism: a fractal approach

open access: yes, 2010
Snow is a porous disordered medium consisting of air and three water phases: ice, vapour and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton.

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.

Comparing measurements of snow mechanical properties relevant for slab avalanche release

open access: yesJournal of Glaciology, 2019
Snow properties relevant to the fracture processes involved in dry-snow slab avalanche release include weak layer specific fracture energy, slab elastic modulus and density.
