Small scale spatial variability of snow density and depth over complex alpine terrain: Implications for estimating snow water equivalent [PDF]
Advances in Water Resources, 2013 This study analyzes spatial variability of snow depth and density from measurements made in February and April of 2010 and 2011 in three 1–2 km2 areas within a valley of the central Spanish Pyrenees.

Predicting snow density using meteorological data [PDF]
Meteorological Applications, 2007 AbstractThis paper presents a simple method for predicting snow density by use of weather data. Six hundred and eight snow density (bulk weight density) measurements from the period 1967–1986 are used in a multiple regression analysis. The measurements are performed at 105 sites in the Ås area situated in Akershus County in southeast Norway.

Water Resources Research, 2019 Snow depth observations and modeled snow density can be combined to calculate snow water equivalent (SWE). In this approach, SWE uncertainty is dominated by snow density uncertainty, which depends on meteorological data quality and process representation

Mapping snow density through thermal inertia observations
Remote Sensing of Environment, 2023 Snow, as a fundamental reservoir of freshwater, is a crucial natural resource. Specifically, knowledge of snow density spatial and temporal variability could improve modelling of snow water equivalent, which is relevant for managing freshwater resources in context of ongoing climate change. The possibility of estimating snow density from remote sensing

Estimating Daily Snow Density Through a Spatiotemporal Random Forest Model
Water Resources ResearchSnow density is of paramount importance in water resource management, snow avalanche warning, and climate change research. However, the lack of competent methods for long‐term and vast‐scale snow density mapping persists due to the intricate ...

Relationship between Density of Newly Fallen Snow and Form of Snow Crystals [PDF]
Nature, 1962 IT has been suggested1 that there should be a relationship between the density of a snowfall and the shape and size of the predominant snow crystal form which makes up the snowfall.

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.

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.

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 ...
