source: NEMO/releases/release-4.0/cfgs/SPITZ12/EXPREF/namelist_ice_cfg @ 10910

Last change on this file since 10910 was 10910, checked in by clem, 19 months ago

Major change: the advection scheme UMx has been revisited to clean all the unphysical values which occured. Minor change: the ref config SPITZ12 has been slightly modified to test more parameterizations that are available in the code (melt ponds and landfast)
