Snowpit snow water equivalent collected with an ETH tube during the MOSAiC expedition

DOI

SWE is the amount of water contained within the snowpack. To determine SWE, the snow depth and density are required. Snow depth (HS) is related to SWE by the local bulk density of snow (ρb): SWE = HS ρb / ρw, where HS is measured in mm, ρb in kg m−3, ρw is the density of water (1000 kg m−3), and SWE is measured in mm of water equivalent. At each snowpit, the ETH-SWE tube, was inserted into the snow vertically and then sealed at the bottom. The weight of the snow inside the cylindrical tube was then measured with a spring scale. If the snow cover is deeper than 0.45 m (height of the tube), then the SWE must be measured in several steps, using a ruler to note the snow height that the sample was taken from. The total water equivalent of the snow cover must be calculated as the sum of the vertically aligned samples. This dataset records the individual sample measurements, explaining why there may be multiple data entries for one snowpit event. We also measured the height of snow in each measurement, so we can back-calculate the snow density using an independent method.Please direct inquiries to; David Wagner (PS122/1), Martin Schneebeli (PS122/2), Amy Macfarlane (PS122/3 and PS122/4), Ruzica Dadic (PS122/5).
