“…More sophisticated approaches capable of simulating complex energy exchanges at the bedrock-atmosphere interface have been proposed to model surface temperature of steep mountain slopes using specific algorithms to compute solar radiations (Stocker-Mittaz et al, 2002;Gruber et al, 2004; and heterogeneous snow accumulation effects (Pogliotti, 2011;Haberkorn et al, 2015aHaberkorn et al, , b, 2017Magnin et al, 2017). However such complex approaches induce a high degree of uncertainty due to the numerous input variables owning to their respective sources of error.…”

“…We observe a maximum difference of 0.7 • C between measured and modelled value at 10 m depth for the observation period, with a mean difference of 0.1 • C between the 60 measured points (two 3-4 months interruptions of the borehole records decrease the number of available data) and simulated temperatures at the same date. On the SE face, the almost continuous snow cover from autumn to spring/early summer (Magnin et al, 2017) and the high solar irradiation both affect the rock temperatures, which is not considered in the modelling approach. The solar radiation effect is visible on the measured profile from 1 July (Fig.…”

“…Several studies have been undertaken on this topic in European mountains (Haeberli, 1973;Grüber and Hoelzle, 2001;Luetschg et al, 2008;Farbrot et al, 2011Farbrot et al, , 2013Hasler et al, 2011;Pogliotti, 2011;Gisnås et al, 2014;Ardelean et al, 2015;Magnin et al, 2016;Beniston et al, 2017), in Japan (Ishikawa, 2003;Ishikawa and Hirakawa, 2000), in the Canadian Rocky Mountains (Harris, 1981;Lewkowicz and Ednie, Lewkowicz et al, 2012;Bonnaventure et al, 2012;Hasler et al, 2015), and most recently in the Andes (Apaloo et al 2012). The snow cover acts as a buffer layer controlling heat loss at the ground interface.…”
