SURFACE SNOW DENSITY OF EAST ANTARCTICA DERIVED FROM IN-SITU OBSERVATIONS
Surface snow density Matrix completion Empirical Orthogonal Function Kriging
2018/5/15
Models based on physical principles or semi-empirical parameterizations have used to compute the firn density, which is essential for the study of surface processes in the Antarctic ice sheet. However...
VALIDATION OF THE DAILY PASSIVE MICROWAVE SNOW DEPTH PRODUCTS OVER NORTHERN CHINA
Snow Depth Products Snow Cover Passive Microwave Validation Northern China
2018/5/15
Passive microwave sensors have the capability to provide information on snow depth (SD), which is critically important for hydrological modeling and water resource management. However, the different a...

Coal mine dust lowers spectral reflectance Arctic snow up to 84 percent
2017/2/16
Dust released by an active coal mine in Svalbard, Norway, reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new University of Colorado Boulder-led research.The ...
Theory of cooperation in a micro-organismal snow-drift game
Theory micro-organismal snow-drift game
2010/11/12
We present a mean field model for the phase diagram of a community of micro-organisms, interacting through their metabolism so that they are, in effect, engaging in a cooperative social game. We show ...
Modelling longwave radiation to snow beneath forest canopies using hemispherical photography or linear regression
forest snow canopy radiation modelling longwave radiation hemispherical photography
2014/4/3
Forest canopies reduce shortwave radiation and increase longwave radiation reaching the underlying surface, compared with
open areas, and thus influence rates at which forest snowpacks melt. Th...
Estimating sub-canopy shortwave irradiance to melting snow on forested slopes
snow hydrology sub-canopy radiation forest transmissivity snowmelt energy needle-leaf forest mountain hydrology
2014/4/3
Estimates of shortwave irradiance energy beneath needle-leaf forests over complex terrain are needed to drive energy balance
snowmelt models and to evaluate the potential hydrological impacts of fore...
