Аннотация: The spatial and temporal variability of the snow cover characteristics and identification of the corresponding changes in snow structure and snow cover properties can be assessed by different techniques. However, each of the methods has certain limitation and the results are rarely accurately compared due to rare possibility of simultaneous use of different devices. The aim of the study was to understand the "background" variability of various snow cover characteristics as represented by different methods. The study site was flat and uniform in vegetation area at the Meteorological observatory of the Lomonosov Moscow State University (Moscow). The involved methods included: Leica Viva (GS08, GS10) cm-accuracy measurements of the positions of the basic points at the ground and the snow cover surface with mathematical analysis of the results by Leica Geo Office-8 and Leica Infinity; results of measurements by Scanning tacheometer Leica Nova MS60; results of drone surface scanning with standard optical camera attached to the drone; 20-m-length snowpits with snow depth and snow structure description; and the SnowMicropen profiles with 50-cm intervals along these snowpit. Additionally, snow depth by ultrasonic sensor and the standard meteorological data were recorded. The data analysis showed high variability in snow depth and snow structure despite the uniform morphological conditions and assumingly uniform micro-meteorological conditions over whole the area. The differences in the variability as presented by different techniques is discussed.
