Multi-year time series of daily solute and isotope measurements from three Swiss pre-Alpine catchments

Time series analyses of solute concentrations in streamwater and precipitation are powerful tools for unraveling the interplay of hydrological and biogeochemical processes at the catchment scale. While such datasets are available for many sites around the ...

Influence of sun cups on surface albedo of wet Alpine snowpack

Michael Lehning, Mathias Thierry Pierre Bavay, Francesca Carletti

In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...

Impact of intercepted and sub-canopy snow microstructure on snowpack response to rain-on-snow events under a boreal canopy

Michael Lehning, Adrien Michel, Nander Wever, Daniel Nadeau, Benjamin Bouchard

Rain-on-snow events can cause severe flooding in snow-dominated regions. These are expected to become more frequent in the future as climate change shifts the precipitation from snowfall to rainfall. However, little is known about how winter rainfall inter ...

Towards a fully physical representation of snow on Arctic sea ice using a 3D snow-atmosphere model

Michael Lehning, Adrien Michel, Mahdi Jafari, Océane Hames, Nander Wever, Marc Schneebeli Zeugin, David Nicholas Wagner

In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...

Hydrological trends for three headwater catchments in the Alptal valley, Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

Hydrological research in the Alptal valley in central Switzerland started in the late 1960s and has mainly focused on the runoff mechanisms that lead to the very quick runoff response, the relation between forest management and floods, biogeochemistry and ...

Surface snow isotopic composition: Post-depositional processes in an alpine snowpack

Michael Lehning, Luca Bianchi, Yoann Nicolas Sadowski

Stable water isotopes are natural tracers allowing to reconstruct the history of a water parcel. They are used as climate proxies and to better understand the hydrological cycle. The snow isotopic composition is directly influenced by temperatures and atmo ...

Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...

A comparison of hydrological models with different level of complexity in Alpine regions in the context of climate change

Michael Lehning, Adrien Michel, Mathias Thierry Pierre Bavay, Francesca Carletti

This study compares the ability of two degree-day models (Poli-Hydro and a degree-day implementation of Alpine3D) and one full energy-balance melt model (Alpine3D) to predict the discharge on two partly glacierized Alpine catchments of different size and i ...

Dissolved major and trace geochemical dynamics in Antarctic lacustrine systems

Tyler Joe Kohler

Clearwater Mesa Uames Ross Island, northeast Antarctic Peninsula) provides a unique opportunity to study solute dynamics and geochemical weathering in the pristine lacustrine systems of a high latitude environment. In order to determine major controls on t ...

Recent patterns of discharge and sediment output of the Gorner Glacier, Switzerland

François Mettra

Recent climate change is causing rapid retreat of alpine glaciers around the globe. As ice melts and glaciers thin, glacier motion and subglacial processes will change. One of the most relevant aspects for down-valley environments, settlements and infrastr ...
