Monitoring and modelling snow interactions with its environment in polar and alpine regions helps understand deeper the processes involved, while developing prediction tools regarding the impact of climate change and risks management in these areas.

This project investigates important processes driving snow deposition and ablation patterns on mountains. We apply process understanding at very small scales (1m) to larger scale (1km) behavior in a catchment.

Water temperature is a physical parameter which affects the habitat suitability of many living beings and directly controls the toxicity of some dissolved substances. In the context of climate change there is some raising concern about the future “health” of our rivers.

The total deposition of precipitation in Antarctica is currently poorly understood. Model predictions cannot be confirmed by local measurements, which are sparse and difficult due to high winds.

The mountainous parts of Switzerland provide much for the country: spectacular landscape, wildlife, tourism, energy and agriculture, to name but a few. In coming years, the country’s energy system will undergo a transition towards one dominated by renewable energy.

The assessment of uncertainties of snow measurements remains a challenging problem in snow sciences. Snow cover properties are highly heterogeneous in both space and time, and the representativeness of measurements of snow variables…
