# This is the main user script of LMDZ_Setup. It defines basic options for the simulations, and runs setup.sh.
# Settings such as model and simulation paths are set in lmdz_env.sh. You must modify it to set the current LMDZ_Setup path as <root_dir>.
# Expert options are set directly in setup.sh via <define_expert_options>.
#
# Some expert options in setup.sh :
# * Orchidee version, through the "veget" option
# * Aerosol forcing, through the "aerosols" option
# * Radiation code, through the "rad" option
# * Compilation options (debug, netcdf)

## Using XIOS for IOs: "-xios" (enabled) / "" (disabled)

# Using or not the Cosp simulator: "-cosp" (enabled) / "" (disabled)

# 2. Simulation setup
#===========================================================

# Initial state and Boundary conditions
# init=   1: to create a new start in INIT
#         0: to read start files in INIT
#       SIM: to read start files from previous simulation SIM0, /!\ SIM0 must be in the same folder as the new SIM
# (limit.nc and aerosols forcing are put in ./LIMIT)
init=1

# climato=1 : Climatological SSTs with 360-day calendar
#        =0 : interannual SSTs with true (ie gregorian) calendar 
climato=1

# Nudging: Can only be activated with climato=0 and freq=mo
# "-nudging" (enabled) / "" (disabled)
nudging=""
#If using nudging, then check DEF/guide.def :
#  - ok_guide will be automatically set to "y" by setup.sh
#  - You may want to check/customize the nudging parameters

# Length of elementary simulations yr (year) or mo (month)
freq="yr"

# Initial/final month for simulation
# If $init=1, the INIT file will be called start.200001.nc,
# but the data correspond in fact to another day.
# NB : the run stops in the BEGINNING of mthend (test "next=stopsim")
mthini=200001
mthend=200501

#-----------------------------------------------------------
# Output files, frequencies, levels 
#   If you use IOIPSL (option xios=""), you may want to choose and customize DEF/config.def. 
#     A few versions are available as DEF/config.def_*; config.def is a copy of config.def_default 
#     See phys_out_filekeys, phys_out_filelevels, phys_out_filetimesteps, and supplementary variables
#   If you use XIOS (option xios="-xios"), check/modify DEF/XMLfiles*/file*xml 
#   In both cases, the default output is "histday".
#-----------------------------------------------------------
# Grid characteristics (regular, zoomed)
#   You may want to choose and customize DEF/gcm.def 
#   A few versions are available as DEF/gcm.def_*; 
#      The default, for regular grid 144x142x79, corresponds to _iperiod7 
#      (Expert : TEMPORARILY : setup.sh forces use of gcm.def_zNAfrica_BiJe for aerosols=spla)

#===========================================================
# 3. Example of calling setup.sh in loop
#===========================================================

# By default, the series is done on one or more of the various versions of physiq.def 
# to be chosen among DEF/PHYS/physiq.def_* , and listed in "physics" :
# NOTE : automatically choosing DEF/PHYS/physiq.def_NPiso for isotopes
