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.pydata_print_output.txtbed_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.

本数据集支撑C. Helanow、N. Iverson、L. Zoet与O. Gagliardini发表的论文《三维基底带空腔的冰川滑移滑动关系》（*Geophysical Res. Lett.* Paper 2019GL084924RR）。本数据集包含主论文第7式所涉变量的数值，用于绘制图1b、图2b、图3以及补充材料中的图S1与图S2。此外，还以Fortran函数的形式提供了生成基底地形所用的函数。

文件与目录说明如下：
1. `data/`：以JSON（JavaScript Object Notation）格式保存的Python字典数据集，文件名遵循主论文中的术语体系。该目录已打包为ZIP压缩文件，执行Python脚本前需先解压。
2. `read_and_print_data.py`：用于读取（加载）`data/`目录下数据集的Python脚本，运行命令为`python read_and_print_data.py`。若以交互模式运行，脚本内置可显式加载数据并依据主论文第7式进行标度转换的函数。
3. `data_print_output.txt`：存储`read_and_print_data.py`运行输出的文本文件，即脚本执行时屏幕上显示的内容。
4. `bed_functions.F90`：包含主论文中基底地形生成所用函数的Fortran源文件。请注意，这些函数依赖于Elmer/Ice专属的Fortran模块，无法独立运行。
