Data for: Comparing observations of subglacial linations to the output of ice sheet models: The Likelihood of Accordant Lineations Analysis (LALA) Tool

NetCDF file of a model simulation of the former British Irish Ice Sheet. Supplement to: Archer, R.E., Ely, J.C., Heaton, T.J., Butcher, F.E.G., Hughes, A.L.C. and Clark, C.D. Comparing observations of subglacial linations to the output of ice sheet models: The Likelihood of Accordant Lineations Analysis (LALA) Tool. Earth Surface Processes and Landforms The folder is provided as a .tar.gz file. This can be uncompressed using a command (linux) such as: tar -xf archive.tar.gz or in Windows using 7zip. Within the folder is output from a numerical model simulation of the former British Irish Ice Sheet, modelled using PISM: https://www.pism.io/ The netcdf file contains several variables, output every 100 years: thk - ice thickness uvel - ice velocity in the x direction vvel - ice velocity in the y direction mask - a mask of ice cover This can be viewed using the ncview software and manipulated in python using packages such as netCDF4 and xarray.

本数据集为前不列颠-爱尔兰冰盖（former British Irish Ice Sheet）模式模拟结果的NetCDF文件（NetCDF file），为以下文献的补充数据：Archer, R.E.、Ely, J.C.、Heaton, T.J.、Butcher, F.E.G.、Hughes, A.L.C. 与 Clark, C.D. 发表于《Earth Surface Processes and Landforms》的论文《将冰下线状构造观测结果与冰盖模式输出结果对比：一致性线状构造分析（Likelihood of Accordant Lineations Analysis，缩写LALA）工具》。
本数据集以.tar.gz压缩包形式提供，Linux系统下可通过`tar -xf archive.tar.gz`命令解压，Windows系统可使用7-Zip软件完成解压。
解压后的文件夹包含前不列颠-爱尔兰冰盖的数值模式模拟结果，该模拟采用PISM模式（PISM）完成，相关官网：https://www.pism.io/。
该NetCDF文件包含多个每100年输出一次的变量：
- thk：冰厚（ice thickness）
- uvel：x方向冰流速（ice velocity in the x direction）
- vvel：y方向冰流速（ice velocity in the y direction）
- mask：冰覆盖掩码（ice cover mask）
可通过ncview软件（ncview）查看该文件，也可借助netCDF4、xarray等Python包对其进行处理。
