An Experimental Investigation on the Size Distribution of Snow Particles during Artificial Snow Making

open access: yesEnergies, 2023
For artificial snowfall, snow particle size can have a direct impact on snow quality. The operating conditions of the snow-makers and environmental factors will influence the atomization and crystallization processes of artificial snow making, which ...

Case Investigation on the Influence of In‐Snow Particles' Size and Composition on the Snow Light Absorption and Albedo

open access: yesGeophysical Research Letters, 2023
The snow physical parameters are closely related to the sizes, shapes, and chemical composition of light‐absorbing particles (LAPs). By utilizing a computer‐controlled scanning electron microscope software called IntelliSEM‐EPASTM, we first report the ...

Sensitivity of modeled snow grain size retrievals to solar geometry, snow particle asphericity, and snowpack impurities [PDF]

open access: yesThe Cryosphere, 2022
Snow grain size is an important metric to determine snow age and metamorphism, but it is difficult to measure. The effective grain size can be derived from spaceborne and airborne radiance measurements due to strong attenuation of near-infrared energy by

Sea salt aerosol production via sublimating wind-blown saline snow particles over sea ice: parameterizations and relevant microphysical mechanisms [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Blowing snow over sea ice has been proposed as a significant source of sea salt aerosol (SSA) (Yang et al., 2008). In this study, using snow salinity data and blowing snow and aerosol particle measurements collected in the Weddell Sea sea ice zone (SIZ ...

Concentration and Physical Characteristics of Black Carbon in Winter Snow of Beijing in 2015

open access: yesAtmosphere, 2021
In Beijing, the probability of snowfall is decreasing as a result of global warming. At the same time, Beijing has suffered severe air pollution. In this paper, the concentration and particle size characteristics of BC (Black Carbon) in snow during the ...

Ensemble mean density and its connection to other microphysical properties of falling snow as observed in Southern Finland [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
In this study measurements collected during winters 2013/2014 and 2014/2015 at the University of Helsinki measurement station in Hyytiälä are used to investigate connections between ensemble mean snow density, particle fall velocity and parameters of the
