O článku:
The aim of the investigation was assessment of spatial variability of the characteristics of snowpack, including
the snow water equivalent (SWE) as the main hydrological characteristic of a seasonal snow cover. The study was performed
in Khibiny Mountains (Russia), where snow density and snow cover stratigraphy were documented with the help
of the SnowMicropen measurements, allowing to determine the exact position of the snow layers’ boundaries with accuracy
of 0.1 cm. The study site was located at the geomorphologically and topographically uniform area with uniform
vegetation cover. The measurement was conducted at maximum seasonal SWE on 27 March 2016. Twenty vertical profiles
were measured along the 10 m long transect. Vertical resolution depended on the thickness of individual layers and
was not less than 10 cm. The spatial variation of the measured snowpack characteristics was substantial even within such
a homogeneous landscape. Bulk snow density variability was similar to the variability in snow height. The total variation
of the snowpack SWE values along the transect was about 20%, which is more than the variability in snow height or
snow density, and should be taken into account in analysis of the results of normally performed in operational hydrology
snow course SWE estimations by snow tubes.
