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.
