Simulating melt crust and ice lens formation in a physically based snowpack model

Michael Lehning, Nander Wever, Charles Fierz

Water flow in a natural snow cover is generally a complex process because of the strongly stratified and changing structure of the snowpack. Important differences in, for example, density and grain size between layers cause sometimes very sharp transitions ...

Event-driven deposition of snow on the Antarctic Plateau: analyzing field measurements with SNOWPACK

Michael Lehning, Charles Fierz

Antarctic surface snow has been studied by means of continuous measurements and observations over a period of 3 yr at Dome C. Snow observations include solid deposits in form of precipitation, diamond dust, or hoar, snow temperatures at several depths, rec ...

Soil Moisture & Snow Properties Determination with GNSS in Alpine Environments: Challenges, Status, and Perspectives

Pierre-André Farine, Jan Skaloud, Cyril Botteron, Steven Vincent Weijs, Jérôme Leclère

Moisture content in the soil and snow in the alpine environment is an important factor, not only for environmentally oriented research, but also for decision making in agriculture and hazard management. Current observation techniques quantifying soil moist ...

A comparison between two statistical and a physically-based model in snow water equivalent mapping

Michael Lehning, Mathias Thierry Pierre Bavay, Tobias Jonas

Snow water equivalent (SWE) estimates at the end of the winter season have been compared for the 2002–2006 period in a 200 km2 mountainous area in Switzerland, using three different models. The first model, ALPINE3D, is a physically based process-oriented ...

The Uncertainty of Seasonal Snow Energy- and Mass Balance Simulations as a Function of Typical Input Uncertainty

Michael Lehning, Mathias Thierry Pierre Bavay, Charles Fierz

The assessment of water resources and their change in time as well as many other applications from hydrology to meteorology require the successful modelling of the dynamics of the seasonal snow cover. Especially if extrapolation in time, e.g. for climate c ...

Snow cover runoff and stream discharge modelling during snow melt in Alpine terrain

Michael Lehning, Nander Wever, Mathias Thierry Pierre Bavay, Charles Fierz

The understanding of the role of snow cover runoff in complex terrain for the hydrological cycle is still limited. Water flow in snow is a complex process, because the strong layering of the snow cover causes strong vertical variation in hydraulic properti ...

Studies of the spatial variability of alpine snowfall using an X-band polarimetric radar

Michael Lehning, Alexis Berne, Danny Eddy Scipion Castillo

A mobile polarimetric X-band radar (MXPol) was deployed in Davos, Switzerland in collaboration with SLF (WSL - Institute for Snow and Avalanche Research). MXPol was installed in the beginning of October 2009 and collected valuable and continuous informatio ...

Drifting snow sublimation: A high-resolution 3-D model with temperature and moisture feedbacks

Michael Lehning, Mathias Thierry Pierre Bavay

The snow transport model of Alpine3D is augmented with a drifting snow sublimation routine. Contrary to other three-dimensional high-resolution snow transport models, Alpine3D now accounts for feedback mechanisms on the air temperature, humidity, and snow ...
