method calc_SWE

calc_SWE(method='avg', ice_layer_density=680)

Functino to compute SWE using three methods: avg SWE for all pit ‘avg’, SWE based on density samples ‘samples’, and SWE based

Args:

  • method (str): ‘avg’, ‘samples’ or ‘layers’. no default - ‘avg’ is simply the - ‘samples’ is density by density samples. Top and bottom layer from all top to all bottom to half between density sample 1;2 and N-1;N. All others, make layer horizons between samples, use density sample in middle of these layers as density - ‘layers’ is density by strat-layer, find matching density sample.Ice layer density a given density.if more than one match, use average. if no matches, search for neareast. (or search for nearest two, upper and lower, and make average)

  • ice_layer_density (int): assign a constant density to ice layers (An ice layer is detected when hand hardness index = knife = 6)

Returns:

  • float: SWE in [cm]

method import_caamlv6

import_caamlv6(print2term=True)

method import_sample_csv

import_sample_csv(bar_plot=False)

Function to import sample profiles.

Args:

  • bar_plot (bool): plot sample profile as bar instead of line-scatter. Default is False

method plot

plot(
    save=False,
    metadata=False,
    invert_depth=False,
    figsize=(8, 4),
    dpi=150,
    plot_order=['temperature', 'density', 'crystal size', 'stratigraphy', 'hardness', 'sample names', 'dD', 'd18O', 'd-ex']
)

Function to plot pit data

Args:

  • save (bool): save plot

  • metadata (bool): add metadata to plot

  • invert_depth (bool): invert depth/height axis. Default is height

  • figsize (tuple): size of plot in inch. default matplotlib setting

  • dpi (int): plot resolution, pixel per inches

  • plot_order (list): list of plots to add to the figure, the order defines the order of the plots

method print_layers

print_layers()

method print_metadata

print_metadata()
