Representative surface snow density on the East Antarctic Plateau [PDF]

open access: yesThe Cryosphere, 2020
Surface mass balances of polar ice sheets are essential to estimate the contribution of ice sheets to sea level rise. Uncertain snow and firn densities lead to significant uncertainties in surface mass balances, especially in the interior regions of the ...

Spatial variation in population-density of snow leopards in a multiple use landscape in Spiti Valley, Trans-Himalaya.

open access: yesPLoS ONE, 2021
The endangered snow leopard Panthera uncia occurs in human use landscapes in the mountains of South and Central Asia. Conservationists generally agree that snow leopards must be conserved through a land-sharing approach, rather than land-sparing in the ...

Linking lidar multiple scattering profiles to snow depth and snow density: an analytical radiative transfer analysis and the implications for remote sensing of snow

open access: yesFrontiers in Remote Sensing, 2023
Lidar multiple scattering measurements provide the probability distribution of the distance laser light travels inside snow. Based on an analytic two-stream radiative transfer solution, the present study demonstrates why/how these lidar measurements can ...

Brief communication: Light-absorbing impurities can reduce the density of melting snow [PDF]

open access: yesThe Cryosphere, 2014
Climatic effects of black carbon (BC) deposition on snow have been proposed to result from reduced snow albedo and increased melt due to light-absorbing particles.

Snow Depth and Snow Density at Resolute, Northwest Territories [PDF]

open access: yesJournal of Glaciology, 1960
Abstract Observations of the snow depth at 21 sites at Resolute were made twice weekly during the winter of 1957–58. As a result of these observations, and of other observations on snow made for the National Research Council, it is shown that the snow depth and the water content of the snow did not continue to ...

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 ...

A Snow Density Dataset for Improving Surface Boundary Conditions in Greenland Ice Sheet Firn Modeling

open access: yesFrontiers in Earth Science, 2018
The surface snow density of glaciers and ice sheets is of fundamental importance in converting volume to mass in both altimetry and surface mass balance studies, yet it is often poorly constrained.

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 ...

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 ...

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 ...
