Study of a temperature gradient metamorphism of snow from 3-D images: time evolution of microstructures, physical properties and their associated anisotropy [PDF]
We carried out a study to monitor the time evolution of microstructural and physical properties of snow during temperature gradient metamorphism: a snow slab was subjected to a constant temperature gradient in the vertical direction for 3 weeks in a cold

Effect of snow microstructure variability on Ku-band radar snow water equivalent retrievals [PDF]
Abstract. Spatial variability in snowpack properties negatively impacts our capacity to make direct measurements of snow water equivalent (SWE) using satellites. A comprehensive data set of snow microstructure (94 profiles at 36 sites) and snow layer thickness (9000 vertical profiles across 9 trenches) collected over two winters at Trail Valley Creek ...

Sensitivity of Spatial Snowmelt Simulations to Radiative Forcing and Model Top Layer Thickness
Abstract Hydrologic models applied in snow‐dominated basins are typically evaluated by comparing simulated outputs, such as snow water equivalent and streamflow, with observations. However, this approach may overlook the energy balance aspect of snow modeling. Snowmelt initiation and rate are primarily determined by the net energy balance, which varies

Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]
During the 2010/11 boreal winter, a distributed set of backscatter measurements was collected using a ground-based Ku-band (17.2 GHz) scatterometer system at 26 open tundra sites.

What SAR Labels Hide About a Changing Arctic
Abstract Synthetic aperture radar (SAR) has been the backbone of Arctic sea ice monitoring since the 1990s, yet nearly every operational product that assigns an ice class or geophysical state (melt onset dates, freeze‐up timing, ice‐type classifications) is derived by compressing continuous radar backscatter into discrete categorical labels.

Wind enhances differential air advection in surface snow at sub-meter scales [PDF]
Atmospheric pressure gradients and pressure fluctuations drive within-snow air movement that enhances gas mobility through interstitial pore space.

Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).

Soil erosion by snow gliding - a first quantification attempt in a subalpine area in Switzerland [PDF]
Snow processes might be one important driver of soil erosion in Alpine grasslands and thus the unknown variable when erosion modelling is attempted.
