    215   the stem name of the NetCDF file to be opened. 
     230\item [File name]: the stem name of the NetCDF file to be opened. 
    216231  This stem will be completed automatically by the model, with the addition of a '.nc' at its end and 
    217232  by date information and possibly a prefix (when using AGRIF). 
    218233  \autoref{tab:SBC_fldread} provides the resulting file name in all possible cases according to 
    219234  whether it is a climatological file or not, and to the open/close frequency (see below for definition).

    249   the frequency of the records contained in the input file. 
     261\item [Record frequency]: the frequency of the records contained in the input file. 
    250262  Its unit is in hours if it is positive (for example 24 for daily forcing) or in months if negative 
    251263  (for example -1 for monthly forcing or -12 for annual forcing). 
    252264  Note that this frequency must REALLY be an integer and not a real. 
    253265  On some computers, setting it to '24.' can be interpreted as 240! 
    254  
    255 \item [Variable name]: 
    256   the name of the variable to be read in the input NetCDF file.

     267\item [Time interpolation]: a logical to activate, or not, the time interpolation. 
    260268  If set to 'false', the forcing will have a steplike shape remaining constant during each forcing period. 
    261269  For example, when using a daily forcing without time interpolation, the forcing remaining constant from 
     
    265273  For example, when using a daily forcing with time interpolation, 
    266274  linear interpolation will be performed between mid-day of two consecutive days. 
    267  
    268 \item [Climatological forcing]: 
    269   a logical to specify if a input file contains climatological forcing which can be cycle in time, 
     275\item [Climatological forcing]: a logical to specify if a input file contains climatological forcing which can be cycle in time, 
    270276  or an interannual forcing which will requires additional files if 
    271277  the period covered by the simulation exceeds the one of the file. 
    272278  See the above file naming strategy which impacts the expected name of the file to be opened. 
    273  
    274 \item [Open/close frequency]: 
    275   the frequency at which forcing files must be opened/closed. 
     279\item [Open/close frequency]: the frequency at which forcing files must be opened/closed. 
    276280  Four cases are coded: 
    277281  'daily', 'weekLLL' (with 'LLL' the first 3 letters of the first day of the week), 'monthly' and 'yearly' which 
     
    280284  For example, the first record of a yearly file containing daily data is Jan 1st even if 
    281285  the experiment is not starting at the beginning of the year.

    480   This routine initialises the rest of the model and repeatedly calls the stp time stepping routine (\mdl{step}). 
     479\item \mdl{nemogcm}: This routine initialises the rest of the model and repeatedly calls the stp time stepping routine (\mdl{step}). 
    481480  Since the ocean state is not calculated all associated initialisations have been removed. 
    482 \item \mdl{step}: 
    483   The main time stepping routine now only needs to call the sbc routine (and a few utility functions). 
    484 \item \mdl{sbcmod}: 
    485   This has been cut down and now only calculates surface forcing and the ice model required. 
     481\item \mdl{step}: The main time stepping routine now only needs to call the sbc routine (and a few utility functions). 
     482\item \mdl{sbcmod}: This has been cut down and now only calculates surface forcing and the ice model required. 
    486483  New surface modules that can function when only the surface level of the ocean state is defined can also be added 
    487484  (\eg\ icebergs). 
    488 \item \mdl{daymod}: 
    489   No ocean restarts are read or written (though the ice model restarts are retained), 
     485\item \mdl{daymod}: No ocean restarts are read or written (though the ice model restarts are retained), 
    490486  so calls to restart functions have been removed. 
    491487  This also means that the calendar cannot be controlled by time in a restart file, 
    492488  so the user must check that nn\_date0 in the model namelist is correct for his or her purposes. 
    493 \item \mdl{stpctl}: 
    494   Since there is no free surface solver, references to it have been removed from \rou{stp\_ctl} module. 
    495 \item \mdl{diawri}: 
    496   All 3D data have been removed from the output. 
     489\item \mdl{stpctl}: Since there is no free surface solver, references to it have been removed from \rou{stp\_ctl} module.

    624   The NCAR bulk formulae have been developed by \citet{large.yeager_rpt04}. 
     616\item NCAR (\np[=.true.]{ln_NCAR}{ln\_NCAR}): The NCAR bulk formulae have been developed by \citet{large.yeager_rpt04}. 
    625617  They have been designed to handle the NCAR forcing, a mixture of NCEP reanalysis and satellite data. 
    626618  They use an inertial dissipative method to compute the turbulent transfer coefficients 
     
    630622  Note that substituting ERA40 to NCEP reanalysis fields does not require changes in the bulk formulea themself. 
    631623  This is the so-called DRAKKAR Forcing Set (DFS) \citep{brodeau.barnier.ea_OM10}. 
    632 \item COARE 3.0 (\np[=.true.]{ln_COARE_3p0}{ln\_COARE\_3p0}):
