Variables
dataset_code
  • Label: Dataset Code
  • Definition: Internal dataset code.
  • Type: Nominal
  • Missing values: None specified
site
  • Label: Site
  • Definition: Location where sample was collected.
  • Type: Nominal
  • Missing values: None specified
sample_height_rel
  • Label: Relative sample height
  • Definition: Height above the ground where sample was collected. Relative terms (bottom lower, bottom middle, bottom upper, middle, top) loosely correspond with ~ 5, 10, 20, 50, 100 cm above the surface.
  • Type: Nominal
  • Missing values: None specified
sample_height_cm
  • Label: Sample height
  • Definition: Approximate sample height. The aeolian material collection trays were initially set to standardized heights above the surface (5, 10, 20, 50, and 100 cm). However, strong winds generated variation in heights among the individual units. Relative terms (bottom lower, bottom middle, bottom upper, middle, top) loosely correspond with ~ 5, 10, 20, 50, 100 cm above the surface.
