    • NULL = None given
BAG_MASS
  • Label:
  • Definition: Mass of the bag before adding snow
  • Type: Physical quantity
  • Unit: gram
  • Maximum: Not specified
  • Minimum: Not specified
  • Precision: 0.1
  • Missing values:
    • NULL = None given
SNOW_MASS
  • Label:
  • Definition: Subtraction of the mass of the bag from the total mass
  • Type: Physical quantity
  • Unit: gram
  • Maximum: Not specified
  • Minimum: Not specified
  • Precision: 0.1
  • Missing values:
    • NULL = None given
DENSITY
  • Label:
  • Definition: Snow mass divided by 100cm3, which the volume of the sampling tool used to extract the snow sample
  • Type: Physical quantity
  • Unit: gramsPerCubicCentimeter
  • Maximum: 1
  • Minimum: 0
  • Precision: 0.1
  • Missing values:
    • NULL = None given
WEIGHTED_DENSITY
  • Label:
  • Definition: the density times the thickness of the layer, which is used to weight the density if there are more than one layer in the pit
  • Type: Physical quantity

SDC
  • Label:
  • Definition: (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.
  • Type: Nominal
  • Missing values: None specified
LAYER_DESCRIPTION
  • Label:
  • Definition: Field observations of the snow layer: hardness of the snow, and snow grain shapes and sizes.
  • Type: Nominal
  • Missing values: None specified
COMMENTS
  • Label:
  • Definition: Notes on snow density measurements
  • Type: Nominal
  • Missing values: None specified

  • Type: Nominal
  • Missing values: None specified
FILE NAME
  • Label:
  • Definition: RAW DATA FILE CONTAINING INFORMATION
  • Type: Nominal
  • Missing values: None specified
