LAYERNominalUnit of snow identified as distinct by hardness from other units in a snow pit.
THICKNESSPhysical quantityHeight of distinct layer in snow pit
TOTAL_MASSPhysical quantityMass of snow and bag measured by a scale in the field
SNOW_MASSPhysical quantity Subtraction of the mass of the bag from the total mass
DENSITYPhysical quantitySnow mass divided by 100cm3, which the volume of the sampling tool used to extract the snow sample
WEIGHTED_DENSITYPhysical quantitythe density times the thickness of the layer, which is used to weight the density if there are more than one layer in the pit
AVG_SNOWPACK_DENSITYPhysical quantitythe sum of the weighted densities dived by the sum of the thickness of all the layers.
SDCNominal(snow density competency) - a qualitative description of how readable the sample was extracted from the snow pit. One (1) indicates that a good sample, with little snow loss was collected, 2 indicates some loss of snow, while 3 indicates that obtaining a nearly complete sample was not possible due to either the lack of cohesion of the snow or the snow wasto hard to collect a sample.
