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

Vertical profile of snow-firn density in the vicinity of Vostok station, Central Antarctica
Лëд 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?
Frontiers 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.

Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]
, 2015 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.

Parameterization of the snow density in the top snow layer.
Journal of the Japanese Society of Snow and Ice, 1988 積雪表層数cmの密度の時間変化を, 粘性圧縮理論に基づいてパラメータ化した.圧縮粘性係数は, 積雪密度と平均気温の関数として表した.計算結果によれば, 積雪密度は最終降雪後, 時間と共に増加し, 高温時の方が低温時よりも増加速度が大きい.密度の計算値と実測値は±0.05g・cm-3の精度で一致した.

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.
