Advances in newly-fallen snow density research
暴雨灾害, 2020 The prediction of newly-fallen snow depth is a key and difficult task for winter meteorological service in Northern China. The es-timation of newly-fallen snow density is its essential technology. In this paper we review the important influencing factors

Standard and non-standard primordial neutrinos [PDF]
, 2006 The standard cosmological model predicts the existence of a cosmic neutrino background with a present density of about 110 cm^{-3} per flavour, which affects big-bang nucleosynthesis, cosmic microwave background anisotropies, and the evolution of large ...

Frontiers in Remote Sensing, 2022 Snow depth can be mapped from airborne platforms and measured in situ rapidly, but manual snow density and snow water equivalent (SWE) measurements are time consuming to obtain using traditional survey methods.

A simple model for predicting snow albedo decay using observations from the Community Collaborative Rain, Hail, and Snow-Albedo (CoCoRAHS-Albedo) Network [PDF]
, 2017 The albedo of seasonal snow cover plays an important role in the global climate system due to its influence on Earth’s radiation budget and energy balance.

Snow accumulation, surface height change, and firn densification at Summit, Greenland: Insights from 2 years of in situ observation [PDF]
, 2004 Weekly measurements of surface height change were made at an accumulation forest of 100 stakes at Summit, Greenland, over a 2-year period (17 August 2000 to 8 August 2002).

Density Variations in Alpine Snow [PDF]
Journal of Glaciology, 1967 AbstractStratigraphic studies of the annual snow layer in the Beartooth Mountains of south-western Montana and on Mount Logan in the St. Elias Range have disclosed a similiar distribution of at least one physical property of the snow pack in the two areas.

Acoustic impedance measurement of snow density [PDF]
Annals of Glaciology, 1998 Today, it is possible to estimate the density of snow in many different ways (gravimetry, attenuation of gamma rays and velocity of electromagnetic waves). In this paper, we suggest using the acoustic properties of snow. First, we recall the main studies on the acoustic properties of snow.

Development of the Surface Urban Energy and Water balance Scheme (SUEWS) for cold climate cities [PDF]
, 2014 The Surface Urban Energy and Water Balance Scheme (SUEWS) is developed to include snow. The processes addressed include accumulation of snow on the different urban surface types: snow albedo and density aging, snow melting and re-freezing of meltwater ...

Equivalent snow density to estimate snow load in extremely heavy snow areas
Journal of the Japanese Society of Snow and Ice, 2004 約10年にわたる山地積雪観測ネットワークによる積雪深および積雪重量の連続観測結果に基づき,最大積雪深から最大積雪重量を算定するための等価積雪密度の新たな実用式を提案した.これは,本州に限定されるが,最大積雪深が3mを超えると,従来のすべての設計指針に示された値より大きくなる.今後,多雪地の雪荷重を推定する場合は,用いる等価積雪密度に注意を払う必要がある.
