How to use the data

  • Choose the type of boundary condition you want to use. Look at the available data below, and at the ice-sheet gallery page.
    • Do not forget to document what you have chosen!
  • Read the appropriate paper(s) in the References above
  • After processing the boundary condition data, send a copy the BC data as seen by your model to Jean-Yves Peterschmitt: netCDF file and plot

Ice-sheet data

The input data for the boundary conditions is available in netCDF files provided by Dick Peltier and Lev Tarasov. You will find below some technical details about the data, and the related publications to cite

Data history

The data files may change a bit (rename or standardize the data, etc…) and you will find the change list below
