SPINUP_ANALYTIC

1.1 create new experiment folder

cd ../../config/ORCHIDEE_OL/
cp -fr SPINUP_ANALYTIC/ MY_SPINUP_ANALYTIC/
cd MY_SPINUP_ANALYTIC/

1.2 tell libIGCM about the new input files (they are stored on the IMBALANCE-P disk on obelix)

modify the variable "ListNonDel?" in COMP/stomate.card:

ListNonDel= (${R_IN}/SRF/reftemp.nc, .), \	 
(/home/surface3/common/CNP_files/rev00/USDA_SoilSuborder.nc, .), \
(/home/surface3/common/CNP_files/rev00/lithology.nc, .), \
(/home/users/dgoll/ORC_data/N_deposition/LMDzINCA_DEP_2000.nc, .), \
(/home/surface3/common/CNP_files/rev00/deposition.nc, .)

REMARK: Although the file with N deposition is used in sechiba we add the file to the stomate.card. This is needed to ensure it is copied when we restart from a simulation with impose_cn. In that case, the N deposition variable will not be present in the sechiba_restart_out.nc but the libIGCM assumes all sechiba variables are present.

WARNING: the deposition file is a static field at the moment; it does not include N deposition either. At the moment N deposition is set to P deposition in the ORCHIDEE code. Anyway N deposition is not accounted for in the calculations for the N & P cycle for now.

tell that we use the new “soil_param.nc”; in COMP/sechiba.card:

(/home/surface3/common/CNP_files/rev00/soils_param.nc, .), \

1.3 adjust the libIGCM

disable XIOS in COMP/orchidee_ol.card

# Use XIOS as output library instead of IOIPSL
XIOS=n

disable XIOS in PARAM/run.def

# Use XIOS for writing diagnostics file
# defulat = n
XIOS_ORCHIDEE_OK = n

disable XIOS in config.card:

#IOS= (xios, XIOS)

[...]

#IOS= (xios, XIOS)

set the IO frequency to avoid crashes in PARAM/run.def

# Writefrequency in seconds in sechiba_history.nc
# default = 86400.0
WRITE_STEP = 1800.0

# Writefrequency in days in stomate_history.nc
# default = 10.
STOMATE_HIST_DT = 1

add the new flags for the nutrient cycles in PARAM/run.def:

# to activate P cycle set =y
STOMATE_OK_PCYCLE=y
STOMATE_IMPOSE_NP=y
# to activate N cycle set =y
STOMATE_OK_NCYCLE=y
STOMATE_IMPOSE_CN=y
# make sure we dont fake
LD_FAKE_HEIGHT=n
# you can enable mass conservation and stoichiometry checks by =y
STOMATE_MASS_CONSERVATION=y
STOMATE_DSG_DEBUG=y

Nammonium_FILE=LMDzINCA_DEP_2000.nc
Nnitrate_FILE=LMDzINCA_DEP_2000.nc
Nnitrate_VAR = NOY
Nammonium_VAR = NHX
Nfert_FILE=NONE
Nbnf_FILE=NONE
NINPUT_UPDATE=-1

in addition you should add all the PFT and soil parameter values as set in /home/users/dgoll/ORCHIDEE/DEFS_n_CARDS/run.def_NV2

disable river routing if you run on non-global scale in run.def

# Activate river routing
RIVER_ROUTING = n

1.4 adjust the job as usual

modify config.card as usual (see wiki) REMARK (curie only): If you want to run ORCHIDEE on spatial subdomain (here the example for a single grid box) you need to adjust the number before MPI line:

#OOL= (orchidee_ol, orchidee_ol, 32MPI)
OOL= (orchidee_ol, orchidee_ol, 1MPI)

modify run.def as usual (see wiki) plus if you want to archive, for example in the IMBALANCE-P storage; add to config.card:

ARCHIVE=/home/surface3/dgoll 

1.5 create job

../../../libIGCM/ins_job

1.6 adjust job_file (optional)

Header to run a site scale simulation on obelix
