Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]
The Cryosphere, 2016 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.

, 1958 This report summarizes the data that have been reflected on snow density since 1947 from selected observation stations across Canada. The relationships between snow density and meteorological parables, particularly wind velocity and air temperature, are discussed.

, 2013 Snow density is an important measure in hydrological applications. It is used to convert snow depth to the snow water equivalent (SWE). A model developed by Sturm et al. (2010) predicts the snow density by using snow depth, the snow age and a snow class defined by the location.

Snow Particle Analyzer for Simultaneous Measurements of Snow Density and Morphology
Journal 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 ...

What drives basin scale spatial variability of snowpack properties in northern Colorado? [PDF]
The Cryosphere, 2014 This study uses a combination of field measurements and Natural Resource Conservation Service (NRCS) operational snow data to understand the drivers of snow density and snow water equivalent (SWE) variability at the basin scale (100s to 1000s km2 ...

Obtaining sub-daily new snow density from automated measurements in high mountain regions [PDF]
Hydrology and Earth System Sciences, 2018 The density of new snow is operationally monitored by meteorological or hydrological services at daily time intervals, or occasionally measured in local field studies.

Performance of snow density measurement systems in snow stratigraphies [PDF]
, 2020 Abstract. Gravimetric and dielectric permittivity measuring systems are applied to measure snow density, but few studies have addressed differences between the two measurement systems under complex snowpack conditions. A field experiment was conducted to measure snow density using the two measurement systems in different stratigraphical layers ...

Seasonal Variability of Snow Density in the Spanish Pyrenees [PDF]
Water, 2021 Spanish latitudes and meteorological conditions cause the snow phenomena to mainly take place in mountainous areas, playing a key role in water resource management, with the Pyrenees as one of the most important and best monitored areas. Based on the most significant dataset of snow density (SDEN) in the Spanish Pyrenees for on-site manual samples and ...

Impulse Radar Snow Surveys – Influence of Snow Density [PDF]
Hydrology Research, 2000 Snow cover water equivalent (SWE) is of major importance for planning of e.g. hydropower production in areas where a large proportion of the annual precipitation falls as snow. Radar technique can be used to determine SWE from the two-way travel time (twt) of a radar-wave propagation through a snowpack.

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