Data supporting "Sliding relations for glacier slip with cavities over three-dimensional beds"

This data supports the paper “Sliding relations for glacier slip with cavities over three-dimensional beds” (Geophysical Res. Lett. Paper 2019GL084924RR) by C. Helanow, N. Iverson, L. Zoet and O. Gagliardini.

The data consists of numerical values for the variables used in equation 7 of the main paper to produce the graphs plotted in figures 1b, 2b and 3 and figures S1 and S2 in the supplementary information. Additionally the functions used to create the bed topographies are provided in the form of Fortran functions.

The files and directories are:

• data/
• read_and_print_data.py
• data_print_output.txt
• bed_functions.F90

data/

Contains the data in a set of python dictionaries saved in JSON format (.json). The naming of the files follows the terminology of the main paper. For the repository this directory is zipped (.zip) and needs to be unzipped before the python script is executed.

read_and_print_data.py

A python script that reads (loads) the data contained data/ and prints it onto the screen. Run as

python read_and_print_data.py

If run interactively, the script contains functions to explicitly load data and scale it accoring to equation 7 in the main paper.

data_print_output.txt

A text file containing the output of read_and_print_data.py (i.e. what is printed on the screen when executed).

bed_functions.F90

A Fortran file containing the functions used for the bed topographies in the main paper. Note that these functions use Fortran modules that are specific to Elmer/Ice and cannot be used stand alone.

python read_and_print_data.py

If run interactively, the script contains functions to explicitly load data and scale it according to equation 7 in the main paper.

data_print_output.txt

A text file containing the output of read_and_print_data.py (i.e. what is printed on the screen when executed).

bed_functions.F90

A Fortran file containing the functions used for the bed topographies in the main paper. Note that these functions use Fortran modules that are specific to Elmer/Ice and cannot be used stand alone.
