Message:

For IPSLCM6.0.9 configuration :

• NEMO : sbccpl.f90, zdftke.f90 and namelist parameters
• LMDZ : renamed *.defNPv6.0.8.1 into *.def_NPv6.0.9 and activation of the use of NPv6.0.9

Location:

CONFIG/UNIFORM/v6/IPSLCM6/GENERAL/PARAM

Files:

• gcm.def_144x142_NPv6.0.9 (moved) (moved from CONFIG/UNIFORM/v6/IPSLCM6/GENERAL/PARAM/gcm.def_144x142_NPv6.0.8.1)
• namelist_lim3_ORCA1_cfg (modified) (2 diffs)
• physiq.def_NPv6.0.9 (moved) (moved from CONFIG/UNIFORM/v6/IPSLCM6/GENERAL/PARAM/physiq.def_NPv6.0.8.1)
