The high Arctic Bayleva site is located on western Spitsbergen about 3 km from the settlement of Ny Ålesund. Snow water equivalent (SWE) measurements were performed at the Bayelva site during the winter season 2019/2020. The manual measurements consist of measuring the snow depth and weighing a known volume of snow to within ±0.01 kg using a steel tube with a radius of 0.04 m and a length of 0.6 m. If the snow depth exceeds 0.6 m the measurement has to be performed in more than one layer, which can add some uncertainty to the recorded values. In each measurement session several snow pits were dug in a radial pattern around the automatic SWE system, covering approximately the same snow conditions as covered by the footprint of the CS725 in order to validate the automatic measurements. ...
