Performance of snow density measurement systems in snow stratigraphies [PDF]

Hydrology Research, 2021
Gravimetric and dielectric permittivity measurement systems (DMS) are applied to measure snow density, but few studies have addressed differences between the two measurement systems under complex snowpack conditions.

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 ...

Spatiotemporal variation characteristics and influencing factors of snow density in the High Mountain Asia from 1960 to 2023. [PDF]

PLoS ONE
Under the context of climate change, significant variations in snow density have been observed in the High Mountain Asia, however, its spatiotemporal patterns and underlying drivers remain incompletely understood.

Impact of dynamic snow density on GlobSnow snow water equivalent retrieval accuracy [PDF]

The Cryosphere, 2021
Snow water equivalent (SWE) is an important variable in describing global seasonal snow cover. Traditionally, SWE has been measured manually at snow transects or using observations from weather stations.

Snow density climatology across the former USSR [PDF]

The Cryosphere, 2014
Snow density is one of the basic properties used to describe snow cover characteristics, and it is a key factor for linking snow depth and snow water equivalent, which are critical for water resources assessment and modeling inputs.

Towards large-scale daily snow density mapping with spatiotemporally aware model and multi-source data [PDF]

The Cryosphere, 2023
Snow density plays a critical role in estimating water resources and predicting natural disasters such as floods, avalanches, and snowstorms. However, gridded products for snow density are lacking for understanding its spatiotemporal patterns.

Observations and simulations of new snow density in the drifting snow-dominated environment of Antarctica

Journal of Glaciology, 2023
Owing to drifting snow processes, snow accumulation and surface density in polar environments are variable in space and time. We present new field data of manual measurements, repeat terrestrial laser scanning and snow micro-penetrometry from Dronning ...

Dominance of grain size impacts on seasonal snow albedo at deforested sites in New Hampshire [PDF]

, 2017
Snow cover serves as a major control on the surface energy budget in temperate regions due to its high reflectivity compared to underlying surfaces.

Spatio-Temporal Characteristics and Differences in Snow Density between the Tibet Plateau and the Arctic

Remote Sensing, 2023
The Tibet Plateau (TP) and the Arctic are typically cold regions with abundant snow cover, which plays a key role in land surface processes. Knowledge of variations in snow density is essential for understanding hydrology, ecology, and snow cover ...
