PEM:

  • Handling the situation in the layering algorithm when CO2 ice sublimation and H2O ice condensation happen simultaneously.
  • Correction of the incorporation of the sub-surface sublimation tendency into the overall tendency to be more robust.
  • Revision of the layering initialization in the case where there is no "startpem.nc" file.
