Researchers have developed a new computer model for calculating the water content of snowpacks, providing an important tool for water resource managers and avalanche forecasters as well as scientists....
New research suggests that "flash droughts" — like the one that unexpectedly gripped the Southern Rockies and Midwest in the summer of 2012 — could be predicted months in advance using soil moisture a...
Snowpack in California’s Sierra Nevada in 2015 was at the lowest level in the past 500 years, according to a new report led by University of Arizona researchers. The team’s research is the first to s...
A new, two-layer canopy module with thermal inertia as part of the detailed snow model SNOWPACK (version 3.2.1) is presented and evaluated. As a by-product of these new developments, an exhaustive ...
Detailed studies of snow cover processes require models that offer a fine description of the snow cover properties. The detailed snowpack model Crocus is such a scheme, and has been run operationally ...
In a model reliating snow water equivalent to 6 combinations of topo- graphic and forest variables on Marmot Creek experimental basin, 36 per cent of the variance was accounted...
Abstract—An ensemble-based data assimilation approach isdeveloped to characterize the snow water equivalent (SWE)and underlying soil freeze–thaw tate (including the soil surfacetemperature and both so...
Recent ground-based and space borne observations suggest the presence of significant amounts of iodine monoxide in the boundary layer of Antarctica, which are expected to have an impact on the ozone b...
Acetaldehyde is a reactive intermediate in hydrocarbon oxidation. It is both emitted and taken up by snowpacks and photochemical and physical processes are probably involved. Understanding the reactiv...
The specific surface area (SSA) of the snow constitutes a powerful parameter to quantify the exchange of matter and energy between the snow and the atmosphere. However, currently no snow physics model...
Snow accumulation and depletion at specific locations can be monitored from space by observing related variations in microwave brightness temperatures. Using vertically and horizontally polarized br...
Prior microwave measurements of snow water equivalent and liquid water content and conceptualizations of emission and backscattering models are reviewed. The results of an experiment designed to col...
At the experimental plot of Weissfluhjoch in Switzerland, 2,540 m a d . , tritium, deuterium and oxygen-18 have been used to study exchange processes during the build-up and ablation of the snow cov...
Liquid water in a snowpack has been recognized for some time as a quantifiable variable of hydrologic significance. It is also important in the interpretation of snowpack microwave remote sensing da...
Microwave signatures have been found to, be related to variations in snow conditions found on the earth's surface. Most of these observations have been obtained by passive microwave radiometry. In g...
