# Script that prepares the PCMDI-AMIP-1-1-9 files to be read by ce0l in LMDZ. 
# These new files are stored in IGCM/ATM/LIMIT/AMIP.v20230512/original
# and can be used to produce limit.nc files on model grid.
# The input files from input4MIPs should be copied before launching this script. See comments in section 0).
#
# Use previous revision 5011 of this script for preparing version PCMDI-AMIP-1-1-6 files.
# Use previous revision 6059 of this script for preparing version PCMDI-AMIP-1-1-7 files.
