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

open access: yes, 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.

Assessment of the Daily Cloud-Free MODIS Snow-Cover Product for Monitoring the Snow-Cover Phenology over the Qinghai-Tibetan Plateau

open access: yesRemote Sensing, 2017
Snow cover plays a crucial role in surface hydrology and energy balance, especially in the Qinghai-Tibetan Plateau (QTP). This study used 12 years (2000–2011) of ground-observed snow depth at 87 meteorological stations to assess and verify the accuracy ...

Effective Improvement of the Accuracy of Snow Cover Discrimination Using a Random Forests Algorithm Considering Multiple Factors: A Case Study of the Three-Rivers Headwater Region, Tibet Plateau

open access: yesRemote Sensing, 2023
Accurate information on snow cover extent plays a crucial role in understanding regional and global climate change, as well as the water cycle, and supports the sustainable development of socioeconomic systems.

Spatial Variability of Shortwave Irradiance for Snowmelt in Forests [PDF]

open access: yes, 2008
The spatial variation of melt energy can influence snow cover depletion rates and in turn be influenced by the spatial variability of shortwave irradiance to snow.

On the saltation of fresh snow in a wind tunnel: profile characterization and single particle statistics [PDF]

open access: yes, 2008
We present experimental results on the snow drift in a turbulent boundary layer over a flat fresh snow-covered surface. Vertical profiles of mass flux and of the distribution of particle diameters were obtained by means of a pair of Snow Particle ...

A sensitivity study of daytime net radiation during snowmelt to forest canopy and atmospheric conditions [PDF]

open access: yes, 2004
This study investigates the dependence of net radiation at snow surfaces under forest canopies on the overlying canopy density. The daily sum of positive values of net radiation is used as an index of the snowmelt rate.

Evaluation of snow cover and snow depth on the Qinghai–Tibetan Plateau derived from passive microwave remote sensing [PDF]

open access: yesThe Cryosphere, 2017
Snow cover on the Qinghai–Tibetan Plateau (QTP) plays a significant role in the global climate system and is an important water resource for rivers in the high-elevation region of Asia.

Impact of Snow Cover Phenology on the Vegetation Green-Up Date on the Tibetan Plateau

open access: yesRemote Sensing, 2022
Variations in snow cover resulting from global warming inevitably affect alpine vegetation growth on the Tibetan Plateau (TP), but our knowledge of such influences is still limited.

Soil erosion by snow gliding - a first quantification attempt in a subalpine area in Switzerland [PDF]

open access: yes, 2014
Snow processes might be one important driver of soil erosion in Alpine grasslands and thus the unknown variable when erosion modelling is attempted.

Recording microscale variations in snowpack layering using near-infrared photography [PDF]

open access: yes, 2010
Deposition of snow from precipitation and wind events creates layering within seasonal snowpacks. The thickness and horizontal continuity of layers within seasonal snowpacks can be highly variable, due to snow blowing around topography and vegetation ...
