    Mollaret, Coline ; Hilbich, Christin ; Pellet, Cécile ; Flores-Orozco, Adrian ; Delaloye, Reynald ; Hauck, Christian

    In: The Cryosphere, 2019, vol. 13, no. 10, p. 2557–2578

    Mountain permafrost is sensitive to climate change and is expected to gradually degrade in response to the ongoing atmospheric warming trend. Long-term monitoring of the permafrost thermal state is a key task, but problematic where temperatures are close to 0 ∘C because the energy exchange is then dominantly related to latent heat effects associated with phase change (ice–water), rather...

    Monitoring soil moisture from middle to high elevation in Switzerland: set-up and first results from the SOMOMOUNT network

    Pellet, Cécile ; Hauck, Christian

    In: Hydrol. Earth Syst. Sci., 2017, vol. 21, no. 6, p. 3199–3220

    Besides its important role in the energy and water balance at the soil–atmosphere interface, soil moisture can be a particular important factor in mountain environments since it influences the amount of freezing and thawing in the subsurface and can affect the stability of slopes. In spite of its importance, the technical challenges and its strong spatial variability usually prevents soil...
