Snow physical properties measurements

We can find in this file measurements of snow physical properties from every snow sample collected for this experiment. Each line corresponds to a snow layer of a given snow sample. We can find two measurements of snow hardness and two measurements of snow density. Snow hardness was measured with a thin-blade penetrometer (resolution: 0.1 N; certified accuracy of ± 0.6 N). This instrument measures the force required to drive a blade 6 cm deep into the snow. Strictly speaking, hardness should be the force applied divided by the surface area of the contact between the instrument and the snow (1.4 cm2). For simplicity, we just report here the force indicated by the instrument (N, Newton) but it can easily be converted to pressure (Pa, Pascal) by dividing the value by 1.4x10-4 m2. Snow density was measured manually with a 100 cm3 box cutter (kg/m3).
