15) The OFFLIN output fields are adapted to plot their fields with EPyGrAM.

The documentation to plot SURFEX OFFLIN output fields with EPyGrAM is available here.

To make it possible, several changes are applied to the ....OUT.nc output files:

• Each field to be plotted has a new attribute, grid_mapping = "Projection_Type".
• The variable Projection_Type is added to each OUT.nc file and filled according to:
  • the projection of the run,
  • the needs of EPyGrAM to plot it correctly.
• This implies the creation of the new file ol_write_proj.F90.
