Last change on this file since 2372 was 2372, checked in by aclsce, 8 years ago

Modified in order to :

  • use writing of diaptr file by using XIOS library (SOURCES/NEMO and opa9.card)
  • IPSLCM6 specific NEMO sources coherent with updated NEMO revision
  • IPSLCM6 specific NEMO namelist files coherent with updated NEMO revision
  • use only XIOS in LMDZ trunk revision (run.def parameter)
  • coherent TS coherent with output variables (green TSC)
  • significative monitoring (ATM and MBG)
