Athabasca oil sands region snow contains efficient micron and nano-sized ice nucleating particles
Environmental Pollution, 2019The Athabasca Oil Sands Region (AOSR) in Alberta, Canada, is an important source of atmospheric pollutants, such as aerosols, that have repercussions on both the climate and human health. We show that the mean freezing temperature of snow-borne particles from AOSR was elevated (-7.1 ± 1.8 °C), higher than mineral dust which freezes at ∼ -15 °C and is ...

The snow medium is treated as densely packed sticky ice particles following a size distribution. We apply the quasicrystalline approximation (QCA) dense medium theory to calculate the absorption, scattering and emission of snow at multiple frequencies.

A technique is proposed for X-ray electron-probe microanalysis (EPMA) of individual particles of solid snow sediment. Two sample preparation procedures were used to analyze the sediments. The PAP-method and the original bi-exponential model were used for matrix correction and the calculation of elemental composition. A method of calculating composition

AbstractIn this study, snow particle size variability was investigated along a transect in Dronning Maud Land from the coast to the polar plateau. The aim of the study was to better understand the spatial and temporal variations in surface snow properties.

From transport to deposition: Mapping snow distribution under the particle size effects
Physics of FluidsNatural snow is a heterogeneous material whose mechanical properties are significantly influenced by its varying particle size and gradation. This study systematically investigates the effects of snow particle size and gradation on roof snow distribution through integrated computational fluid dynamics (CFD) simulations and wind tunnel tests.

Abstract A simple method has been devised for taking shadow photographs of snow crystals, or of their melt water, without use of a lens. It permits study of the form, size, and mass characteristics at intervals of several minutes during a snowfall. As an application of the method, the coalescence of crystals was studied.
