     43= LMDZOR experience for running the gcm = 
     44This configuration only contains only one directory for running the gcm.e : LMDZOR. This directory can be used for different type of simulation for example AMIP interannual or climatological run. Or nudged run with regular or zoomed grid. Only the .card changes for different run. The PARAM directory and the .driver are the same. Two possibilities are predefined using the different .cards that are available. To do a climatological simulation, use cards with suffix ''_Climat'', do following link : 
     45{{{ 
     46cd LMDZOR/COMP; ln -s lmdz.card_Climat lmdz.card; ln -s orchidee.card_Climat orchidee.card 
     47}}} 
     48Or to do an AMIP interannual simulation use cards with suffix ''_AMIP'', do following link : 
     49{{{ 
     50cd LMDZOR/COMP; ln -s lmdz.card_AMIP lmdz.card; ln -s orchidee.card_AMIP orchidee.card 
     51}}} 
     52 
     53The cards with suffix _Climat correspond to the experience LMDZOR in configuration LMDZ4OR_v3 and the cards with suffix _AMIP correspond to the experience in directory AMIP in LMDZ4OR_v3 configuration. 
     54 
     55Parameters in config.card such as !JobName, !CalendarType, !DateBegin, !DateEnd must always be considered and eventually modified according to desired experience.

     58 
     59= Simulation with nudging = 
     60 
     61=== Interpolation of nudge files === 
     62The files that will be used for the nudging (''fr'' guidage) must be interpolated to the model grid before running the gcm. Scripts to do this are stored in directory CREATE/SCRIPT. To interpolate ERA-Interim use the script [http://forge.ipsl.jussieu.fr/igcmg/browser/CONFIG/LMDZOR/branches/LMDZOR_v4/CREATE/SCRIPT/interp_from_era.ksh interp_from_era.ksh]. You must first modify the beginning of this script. To interpolate LMDZ model output files use the script [http://forge.ipsl.jussieu.fr/igcmg/browser/CONFIG/LMDZOR/branches/LMDZOR_v4/CREATE/SCRIPT/interp_from_TS.ksh interp_from_TS.ksh]. Both scripts depend on the script [http://forge.ipsl.jussieu.fr/igcmg/browser/CONFIG/LMDZOR/branches/LMDZOR_v4/CREATE/SCRIPT/era2gcm.ksh era2gcm.ksh]. These script access the archive directory with a use in ferret. Therefore it is not possible to use them from vargas or brodie. These scripts are tested at mercure and ulam. Follow step 1 to 3 :  
     63 
     641) Create file grilles_gcm.nc[[BR]] 
     65The file grilles_gcm.nc is created by default during the CREATE experience '''if''' you use revision 1508 of LMDZ5/trunk or later and revision 1333 or later of the configuration LMDZOR_v4.  
     66The file grilles_gcm.nc contains the different grids used as target for the interpolation. The file is created with ce0l if the parameter grille_gcm_netcdf=T(default in CREATE). After a normal CREATE experience the file can be found in the archive directory IGCM_OUT/LMDZOR/ELXXXX/ATM/Output/Boundary/. If the grid contains a zoom it is important that the file grilles_gcm.nc is created at the same time as the other boundary conditions and initial state files, using the same .def parameter files describing the grid. 
     67 
     682) Modify and run the script interp_from_era.ksh from a machine that access the ERA files by use in ferret. Script tested at mercure and ulam. [[BR]] 
     69 
     703) Move interpolated files to archive directory.[[BR]] 
     71 
     72=== For running === 
     73Follow 3 steps to activate nudging in LMDZ : [[BR]] 
     74 
     751) Set parameter ok_guide=y in lmdz.card. The lmdz.driver will then put ok_guide=y in the guide.def file.[[BR]] 
     76 
     772) Add files containing the nudging variables in lmdz.card (''_Climat'' or ''_AMIP'') in section !BoundaryFiles. These files have to be interpolated previously to the model horizontal grid.  
     78 
     793) Most probably you have to modify parameter file guide.def containing specifications for the nudging according to your experience.[[BR]]

     83= Using IPSL coupled model output = 
    4284 
    4385Do following steps to create boundary conditions using output from a previous LMDZ run.[[BR]] 
    … …  
    78120To do this, use the script CREATE/SCRIPT/create_sst_anomly.ksh instead of step 1 above. See the script [http://forge.ipsl.jussieu.fr/igcmg/browser/CONFIG/LMDZOR/branches/LMDZOR_v4/CREATE/SCRIPT/create_sst_anomaly.ksh here].

    83 = LMDZOR experience for running the gcm = 
    84 This configuration only contains only one directory for running the gcm.e : LMDZOR. This directory can be used for different type of simulation for example AMIP interannual or climatological run. Or nudged run with regular or zoomed grid. Only the .card changes for different run. The PARAM directory and the .driver are the same. Two possibilities are predefined using the different .cards that are available. To do a climatological simulation, use cards with suffix ''_Climat'', do following link : 
    85 {{{ 
    86 cd LMDZOR/COMP; ln -s lmdz.card_Climat lmdz.card; ln -s orchidee.card_Climat orchidee.card 
    87 }}} 
    88 Or to do an AMIP interannual simulation use cards with suffix ''_AMIP'', do following link : 
    89 {{{ 
    90 cd LMDZOR/COMP; ln -s lmdz.card_AMIP lmdz.card; ln -s orchidee.card_AMIP orchidee.card 
    91 }}} 
    92  
    93 The cards with suffix _Climat correspond to the experience LMDZOR in configuration LMDZ4OR_v3 and the cards with suffix _AMIP correspond to the experience in directory AMIP in LMDZ4OR_v3 configuration. 
    94  
    95 Parameters in config.card such as !JobName, !CalendarType, !DateBegin, !DateEnd must always be considered and eventually modified according to desired experience.
