How to use IPSLCM6 for millinum-like run ?

Model installation

1. Start to import modIPSL: svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
2. Install the model: cd modipsl/util ; ./model IPSLCM6.1-LR
3. If needed, add in code some diagnostics (stratomask, TAU_AER, volcanic response): procedure is describded ​here.
4. Check that compiler is intel2017!!'''
5. Compile: cd modipsl/config/LMDZOR ; gmake

NOTE: file_def_XXX.xml are taken from the model and not in PARAM subdir in default config (this could be changed in lmdz.card).

Simulation config

1. Copy a historical config.card taken from EXPERIMENTS/ dir. Modify JobName=Pmil-mysimu and run ../../libIGCM/ins_job to create simulation directory.
2. Go into simulation dir and modify config.card.
3. If simulation starts before 1800 edit COMP/opa.card and modify TimeOrigin=850 to get correct oceanic ouputs.
4. Edit COMP/orchidee.card to choose correct land use' and 'wood harvest' (starts in 850 so before this date fix to 850):

   List= (${R_IN}/SRF/PFTMAPS/CMIP6/ESA-LUH2v2/historical/15PFT.v1/PFTmap_${year}.nc, PFTmap.nc) ,\
         (${R_IN}/SRF/WOODHARVEST/LUH2v2/historical/woodharvest_${year}.nc, woodharvest.nc)
   

5.Edit COMP/pisces.card to put a 1850 climato for dust and ndeposition as below:

6. Edit 'COMP/lmdz.card` (OZONE will be changed soon to use a yearly file):

Orchidee analytic spin-up

To start simulation with orchidee's analytic spinup (for Carbon stock equilibrium) edit PARAM/orchidee.def_CWRR add or change following options:

# default = 1Y
VEGET_UPDATE = _AUTO_
# Force to read vegetation map at the beginning of the simulation
VEGET_UPDATE_at_start=y

# ORCHIDEE analytical spinup 20Y
SPINUP_ANALYTIC=y
SPINUP_PERIOD=20
