PEM:

  • It is now possible to set the number of initial PCM calls independently of the number of "inter-PEM" PCM calls. It is useful to get a stable situation for the start of the simulation.
  • Correction of a bug: 'reshape_XIOS_output' treated the first two PCM runs instead of the last two. The numbering has been adapted in "launch_pem.sh" to get it right.
  • PEM outputs ("diagpem.nc" and "diagsoil_pem.nc") has been improved: 'Time' now evolves according to 'dt_pem' (usually year by year) and 'ecritpem' is a full variable of "time_evol_mod.F90".

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
