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.

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

Equivalent snow density to estimate snow load in extremely heavy snow areas
約10年にわたる山地積雪観測ネットワークによる積雪深および積雪重量の連続観測結果に基づき,最大積雪深から最大積雪重量を算定するための等価積雪密度の新たな実用式を提案した.これは,本州に限定されるが,最大積雪深が3mを超えると,従来のすべての設計指針に示された値より大きくなる.今後,多雪地の雪荷重を推定する場合は,用いる等価積雪密度に注意を払う必要がある.

Modeling bulk density and snow water equivalent using daily snow depth observations [PDF]
Abstract. Bulk density is a fundamental property of snow relating its depth and mass. Previously, two simple models of bulk density (depending on snow depth, date, and location) have been developed to convert snow depth observations to snow water equivalent (SWE) estimates. However, these models were not intended for application at the daily time step.

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

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]
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.
