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 ...

Snow Particle Analyzer for Simultaneous Measurements of Snow Density and Morphology

open access: yesJournal of Geophysical Research: Atmospheres, 2023
AbstractThe detailed characterization of snow particles is critical for understanding the snow settling behavior and modeling the ground snow accumulation for various applications such as prevention of avalanches and snowmelt‐caused floods, etc. In this study, we present a snow particle analyzer for simultaneous measurements of various properties of ...

Seasonal evolution of snow density and its impact on thermal regime of sea ice during the MOSAiC expedition [PDF]

open access: yesThe Cryosphere
Snow density is a crucial parameter for sea ice modelling at the physical process level. The seasonal evolution of surface (top 3 cm) and bulk (entire layer) snow densities observed during the MOSAiC expedition was investigated and used to assess four ...

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 ...

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 ...

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.

The effects of variation in snow properties on passive microwave snow mass estimation [PDF]

open access: yes, 2012
Estimating snow mass at continental scales is difficult, but important for understanding land-atmosphere interactions, biogeochemical cycles and the hydrology of the Northern latitudes.

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

open access: yesJournal of Glaciology, 1960
AbstractObservations 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 increase during the winter as the snow fell.

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 ...

Observations of snowpack properties to evaluate ground-based microwave remote sensing [PDF]

open access: yes, 2013
Active microwave radar has been shown to have great potential for estimating snow water equivalent (SWE) globally from space. To help evaluate optimal active microwave sensor configurations to observe SWE, we evaluated ground-based Frequency Modulated ...
