Improvements in methods of analyzing dust concentrations, and influence of the storage processes on dust concentrations in polar snow and ice samples

Antarctic Record, 2014
We sought to improve the analytical methods employed when operating a laser particle counter and to evaluate the influence of the storage processes on dust concentrations in polar snow and ice samples.

European In-Situ Snow Measurements: Practices and Purposes

Sensors, 2018
In-situ snow measurements conducted by European institutions for operational, research, and energy business applications were surveyed in the framework of the European Cooperation in Science and Technology (COST) Action ES1404, called “A European network

Size of snow particles in a powder-snow avalanche

, 2009
The size of the snow particles involved in a powder-snow avalanche is a key parameter of the local dynamic of the flow. An experimental device has been realized to collect snow particles within powder-snow avalanches. Snow particles have been captured in the powder-snow part of an avalanche triggered artificially on the experimental test site of the ...

Impact of Magnetohydrodynamic Disk Wind on Early Evolutionary Stage of Protoplanetary Disk and Dust Growth

The Astrophysical Journal
We perform one-dimensional protoplanetary disk evolution calculations to investigate the impact of the magnetohydrodynamic (MHD) disk wind on disk evolution and dust particle growth.

The Precipitation Imaging Package: Assessment of Microphysical and Bulk Characteristics of Snow

Atmosphere, 2020
Remote-sensing observations are needed to estimate the regional and global impacts of snow. However, to retrieve accurate estimates of snow mass and rate, these observations require augmentation through additional information and assumptions about ...

A method to retrieve the spectral complex refractive index and single scattering optical properties of dust deposited in mountain snow

Journal of Glaciology, 2017
Dust deposition to snow can have regionally important climatic and hydrologic impacts resulting from direct reduction of surface albedo and indirectly from the initiation of snow albedo feedbacks.

Wind Tunnel Tests of Wind-Induced Snow Distribution for Cubes with Holes

Advances in Civil Engineering, 2019
The nonuniform distribution of snow around structures with holes is extremely unfavorable for structural safety, and the mechanism of wind-snow interaction between adjacent structures with holes needs to be explored.

Experimental study on the unconfined apparent shear strength of compacted snow

Journal of Glaciology
To address the scarcity of data on compacted snow shear damage under complex conditions, unconfined shear tests were conducted in Northeast China. This study examined apparent shear strength variations with density (300–550 kg·m−3), temperature (−17.4°C ...
