RESPONSE OF ALPINE GRASSLAND VEGETATION PHENOLOGY TO SNOW ACCUMULATION AND MELT IN NAMCO BASIN
Vegetation Greening Vegetation Growth Length Snow Cover Fraction Trend Analysis Relationship Namco Basin
2018/5/11
Snow/ice accumulation and melt, as a vital part of hydrological processes, is close related with vegetation activities. Taking Namco basin for example, based on multisource remote sensing data and the...
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...
Warm Arctic, Cold Continents: A Common Pattern Related to Arctic Sea Ice Melt, Snow Advance, and Extreme Winter Weather
Arctic sea ice statistical model the Eurasian snow winter temperatures
2015/7/16
Arctic sea ice was observed to be at a new record minimum in September 2012. Following this summer minimum, northern Eurasia and much of North America experienced severe winter weather during the wint...
Evaluation of North Eurasian snow-off dates in the ECHAM5.4 atmospheric general circulation model
atmospheric general circulation model North Eurasian snow-off dates
2014/12/19
The timing of springtime end of snowmelt (snow-off date) in northern Eurasia in version 5.4 of the ECHAM5 atmospheric general circulation model (GCM) is evaluated through comparison with a snow-off da...
Development of a new semi-empirical parameterization for below-cloud scavenging of size-resolved aerosol particles by both rain and snow
new semi-empirical parameterization rain
2014/12/18
t. A parameter called the scavenging coefficient 3
is widely used in aerosol chemical transport models (CTMs)
to describe below-cloud scavenging of aerosol particles by
rain and snow. However...
This paper presents a package of modified
temperature-index-based snow water equivalent models as
part of the hydrological modeling system NewAge-JGrass.

Snow water equivalent (SWE) is important for investigations of annual to decadal-scale changes in Arctic environment and energy-water cycles. Passive microwave satellite-based retrieval algorithm esti...
Multi-Satellite and Sensor Derived Trends and Variation of Snow Water Equivalent on the High-Latitudes of the Northern Hemisphere
Arctic Snow Water Equivalent Multi-Satellite Microwave Trends and Variations
2013/3/7
Utilizing more than 30 years of satellite-microwave sensor derived snow water equivalent data on the high-latitudes of the northern hemisphere we investigate regional trends and variations relative to...
The outcome of protoplanetary dust growth: pebbles, boulders, or planetesimals? III. Sedimentation driven coagulation inside the snow-line
Methods Numerical Planets satellites formation Protoplanetary disks
2011/10/20
We investigate dust growth due to settling in a 1D vertical column of a protoplanetary disk. It is known from the observed 10 micron feature in disk SEDs, that small micron-sized grains are present at...
