PEM:

  • Albedo is now updated only at the end of the PEM (and not at every iteration) + Correct way to set it taking into account CO2/H2O ice and frost.
  • Cosmetic cleanings.

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

10! Authors: RV & LL
