In this section the simulations done for ERACLIM2 project are described

== 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 \\

== 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@ipsl.jussieu.fr ou Sophie.Cloche@latmos.ipsl.fr \\

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@lsce.ipsl.fr \\

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: \\
