Currently, in the Swiss alpine region snow depth is measured
at specific locations by automated weather stations or
observers in the field, while both observations are restricted
to flat sites exhibiting a rather homogeneous snow cover
(Bründl et al., 2004; Egli, 2008). These flat field point measurements
are assumed to represent snow cover characteristics
for a larger area around the stations and are therefore interpolated
over large distances and are combined with snow
cover information from optical satellites (Foppa et al., 2007).
This method is unable to capture the small-scale variability
of snow depth. Investigations into the representativeness of
point snow depth measurements on snow depth for entire
catchments are sparse (Grünewald and Lehning, 2014).
