In this section the simulations done for ERACLIM2 project are described

1) Simulations set-up

Resolution : 1 x 1 degree

Model Version: 3977

Meteo forcing files :

/ccc/store/cont003/dsm/p24palm/CERA20C_ORCHIDEE

Run.def is set as follow:

   # Soil resistance
   DO_RSOIL=y

   # Stress on plants 
   STRESS_GS=1.,1.,1.,1.,1.,1.,1.,1.,1.,1.,1.,1.,1.  
   STRESS_GM=1.,1.,1.,1.,1.,1.,1.,1.,1.,1.,1.,1.,1.

2) Where to find the principal files?

Outputs are stored in curie :

/ccc/store/cont003/dsm/p24palm/IGCM_OUT/OL2/PROD/ref3977

Configuration files are:

Spin-up: /ccc/work/cont003/dsm/p24palm/ORCHIDEE_TRUNK/modipsl/config/ORCHIDEE_OL/FG1med.CERA20C.3977
Transient: /ccc/work/cont003/dsm/p24palm/ORCHIDEE_TRUNK/modipsl/config/ORCHIDEE_OL/FG1transmed.CERA20C.3977
Historical: /ccc/work/cont003/dsm/p24palm/ORCHIDEE_TRUNK/modipsl/config/ORCHIDEE_OL/FG2med.CERA20C.3977

3) Where the CERA-20C files are stored and how these kind of files can be downloaded again

Meteorological CERA-20C are temporarily stored here:

/ccc/scratch/cont003/dsm/p24palm/CERA20C/NETCDF/GLOBAL_100/daily/FC_SF

If you want to download other files from ECMWF MARS system please contact:
Sophie Cloché
sbcipsl@… ou Sophie.Cloche@…

In general the files are put in the IDRIS server. So if you want to transfer the files from IDRIS to CURIE or other servers of the LSCE, please contact:
Anne Cozic
anne.cozic@…

A script to make the download from IDRIS to CURIE is here:
/ccc/cont003/home/dsm/p24palm/SYNC_CERA20C/synchro_ecmwf_gaya_to_mercure_2
But to run it the password from Anne is necessary.

4) How the forcing file are built up

The fortran script to transform the raw CERA-20C files in forcing for ORCHIDEE can be found here:

/ccc/work/cont003/dsm/p24palm/makeforc_CERA20C/prepare_forcing_cera20c.f90

To compile it, the following file has to be used:

/ccc/work/cont003/dsm/p24palm/makeforc_CERA20C/compile.sh

The Land-Sea-Mask file (lsm.19000101.fshce2.GLOBAL_100.nc), that is necessary to run the script, is copied in the same folder and it can be also found here:

/ccc/scratch/cont003/dsm/p24palm/CERA20C/NETCDF/GLOBAL_100/daily/FC_SF/lsm.19000101.fshce2.GLOBAL_100.nc

Some parts of the script to verify before running it again are reported below:
