Accuracy of Manual Snow Sampling, Depending on the Sampler’s Cross-Section—A Comparative Study
Snow sampling, either by inserting a tube through the entire snowpack or by taking samples from the vertical profile, is widely applied to measure the snow depth, density, and snow water equivalent (SWE). A comparative study of snow-sampling methods was carried out on 24 March 2022 in Sodankylä, Fin...

A comparative study of snow-sampling methods was carried out on 24 March 2022 in Sodankylä, Finland. Six groups from five countries (Estonia, Finland, Greenland, Iceland, and Sweden) participated, using 12 different snow samplers, including 9 bulk tube samplers and 3 density cutters. The cross-sectional area of the SWE samplers varied from 11 to 100 cm 2 , while tube length varied from 30 cm to 100 cm. The cross-sectional area of the density profile cutters varied from 100 cm 2 to 200 cm 2 and the vertical sampling step varied from 5 cm to 10 cm.
