Investigating ANN architectures and training to estimate snow water equivalent from snow depth [PDF]
Hydrology and Earth System Sciences, 2021 Canada's water cycle is driven mainly by snowmelt. Snow water equivalent (SWE) is the snow-related variable that is most commonly used in hydrology, as it expresses the total quantity of water (solid and liquid) stored in the snowpack.

Georadar Measurements for the Snow Cover Density [PDF]
American Journal of Applied Sciences, 2009 Ground Probing Radar (GPR) devices is adopted for the analysis of thickness and the mechanical properties (density) of the snow cover in some test site in Alps, in Northern Italy. The performances of standard radar systems for the snow cover characterisation are analysed, the main aim is to assess the reliability of the method to estimate the snow ...

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]
The Cryosphere, 2016 Density is a fundamental property of porous media such as snow. A wide range of snow properties and physical processes are linked to density, but few studies have addressed the uncertainty in snow density measurements.

Impacts of landscape and climatic factors on snow cover in the Altai Mountains, China
Advances in Climate Change Research, 2021 Snow properties and their changes are crucial to better understanding of hydrological processes, soil thermal regimes, and surface energy balances. Reliable data and information on snow depth and snow water equivalent (SWE) are also crucial for water ...

Density Variations in Alpine Snow [PDF]
Journal of Glaciology, 1967 AbstractStratigraphic studies of the annual snow layer in the Beartooth Mountains of south-western Montana and on Mount Logan in the St. Elias Range have disclosed a similiar distribution of at least one physical property of the snow pack in the two areas.
