PEM:

  • Correction of a bug when running with ifort, XIOS and no sub-slopes. If compiled with ifort, the 'Reshape' program cashed because of sub-slopes variables were written in the XIOS output but not filled. A new file definition without sub-slopes can be chosen in the xml file to avoid this issue.
  • Addition in the 'Reshape' program of a check to remove the output files if they exist to prevent a crash.

3!=======================================================================
4!
5! Purpose: Read XIOS files, and convert them into the correct PCM grid
6!          XIOS  longitudes start at -180 but stop before -180 (not duplicated)
7!          We basically add the last point, and complete the XIOS file. Looped
8!          over the two PCM runs
