Estimating Snowpack Density from Near-Infrared Spectral Reflectance Using a Hybrid Model

open access: yesRemote Sensing, 2021
Improving the estimation of snow density is a key task in current snow research. Characterization of the variability of density in time and space is essential for the estimation of water equivalent, hydroelectric power production, assessment of natural ...

Vertical profile of snow-firn density in the vicinity of Vostok station, Central Antarctica

open access: yesЛëд и снег, 2023
The density of the snow and firn thickness is one of the fundamental and most important physical properties of the polar ice sheets. The data on density is used for reconstructing the past snow accumulation rate variability based on firn core studies ...

Convection of snow: when and why does it happen?

open access: yesFrontiers in Earth Science, 2023
Convection of water vapor in snowpacks is supposed to have a major impact on snow density and microstructure profiles with strong implications for the thermal regime and snow stability.

Investigating ANN architectures and training to estimate snow water equivalent from snow depth [PDF]

open access: yesHydrology 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.

On the saltation of fresh snow in a wind tunnel: profile characterization and single particle statistics [PDF]

open access: yes, 2008
We present experimental results on the snow drift in a turbulent boundary layer over a flat fresh snow-covered surface. Vertical profiles of mass flux and of the distribution of particle diameters were obtained by means of a pair of Snow Particle ...

Modeling Wet-Snow Shedding from Current-Carrying Conductors [PDF]

open access: yes
The initiation of wet-snow shedding from currentcarrying conductors was studied experimentally and theoretically. A suspended cable with cylindrical snow accretion was considered, and some of the snow properties at the end of sleeve were measured and ...

A prototype passive microwave retrieval algorithm for tundra snow density [PDF]

open access: yesThe Cryosphere
Snow density data are important for a variety of applications, yet, to our knowledge, there are few methods for estimating spatiotemporal varying snow density in the Arctic environment.

ASIRAS airborne radar resolves internal annual layers in the dry-snow zone of Greenland [PDF]

open access: yes, 2006
We present data from the European Space Agency's Airborne SAR/Interferometric Radar Altimeter System (ASIRAS), flown during the CryoVex 2004 field calibration/validation campaign, and new, high-resolution depth profiles of snow density measured in the ...

The Impact of Diffusive Water Vapor Transport on Snow Profiles in Deep and Shallow Snow Covers and on Sea Ice

open access: yesFrontiers in Earth Science, 2020
Water vapor transport has been highlighted as a critical process in Arctic snowpacks, shaping the snow cover structure in terms of density, thermal conductivity, and temperature profile among others.
