    210 ORCA2_OFF_PISCES  shares the same general configuration of ORCA2_ICE_PISCES, but dynamical fields are pre-calculated and stored with 5 days frequency. 
    211 This enables for an offline coupling of all TOP components, here specifically dealing with PISCES biogeochemical model. 
    212  
    213 Pre-calculated dynamical fields are provided to NEMO using the namelist ``&namdta_dyn``  in ``namelist_cfg`` : 
     216ORCA2_OFF_PISCES  shares the same general offline configuration of ORCA2_ICE_TRC, but only PISCES model is an active component of TOP. 
     217 
     218 
     219ORCA2_OFF_TRC 
     220------------- 
     221 
     222ORCA2_OFF_TRC is based on the ORCA2 global ocean configuration (see `ORCA2_ICE_PISCES`_ for general description) along with the tracer passive transport module (TOP), but dynamical fields are pre-calculated and read with specific time frequency. 
     223 
     224This enables for an offline coupling of TOP components, here specifically inorganic carbon compounds (cfc11, cfc12, sf6, c14) and water age module (age). See ``namelist_top_cfg`` to inspect the selection of each component with the dedicated logical keys. 
     225 
     226Pre-calculated dynamical fields are provided to NEMO using the namelist ``&namdta_dyn``  in ``namelist_cfg``, in this case with a 5 days frequency (120 hours):

    221234     ln_dynrnf_depth =  .false.    !  runoffs is spread in vertical (T) or not (F)

    250255Input dynamical fields for this configuration (ORCA2_OFF_v4.0.tar_) comes from a 2000 years long climatological simulation of ORCA2_ICE using ERA40 atmospheric forcing.

    253  
    254  
    255 ORCA2_OFF_TRC 
    256 ------------- 
    257  
    258 ``ORCA2_OFF_TRC`` uses the ORCA2_LIM configuration in which the tracer passive transport module TOP has been 
    259 activated in standalone using the dynamical fields that are pre calculated. 
    260  
    261 See `ORCA2_ICE_PISCES`_ for general description of ORCA2. 
    262  
    263 In ``namelist_top_cfg``, different passive tracers can be activated ( cfc11, cfc12, sf6, c14, age ) or my-trc, 
    264 a user-defined tracer. 
    265  
    266 The dynamical fields are used as input, they are coming from a 2000 years of an ORCA2_LIM climatological run using 
    267 ERA40 atmospheric forcing. 
     257Note that, this configuration default uses linear free surface (``ln_linssh = .true.``) assuming that model mesh is not varying in time and it includes the bottom boundary layer parameterization (``ln_trabbl = .true.``) that requires the provision of bbl coefficients through ``sn_ubl`` and ``sn_vbl`` fields. 
     258 
     259It is also possible to activate PISCES model (see ORCA2_OFF_PISCES_) or a user defined set of tracers and source-sink terms with ``ln_my_trc = .true.`` (and adaptation of trunk/src/TOP/MY_TRC routines). 
     260 
     261In addition, the offline module (OFF) allows for the provision of further fields: 
     262 
     2631. **River runoff** can be provided to TOP components by setting ``ln_dynrnf = .true.`` and by including an input datastream similarly to the following: 
     264 
     265.. code-block:: fortran 
     266 
     267     sn_rnf      = 'dyna_grid_T'           ,       120         , 'sorunoff'  ,  .true.   , .true. , 'yearly'  , ''               , ''       , '' 
     268 
     2692. **VVL dynamical fields**, in the case input data were produced by a dyamical core using variable volume (``ln_linssh = .false.``) it necessary to provide also diverce and E-P at before timestep by including input datastreams similarly to the following 
     270 
     271.. code-block:: fortran 
     272 
     273     sn_div       = 'dyna_grid_T'           ,       120         ,    'e3t'     ,  .true.   , .true. , 'yearly'  , ''               , ''       , '' 
     274     sn_empb      = 'dyna_grid_T'           ,       120         , 'sowaflupb'  ,  .true.   , .true. , 'yearly'  , ''               , ''       , '' 
     275 
     276 
     277More details can be found by inspecting the offline data manager at :trac:`source:/NEMO/trunk/src/OFF/dtadyn.F90`

    269280ORCA2_SAS_ICE 
    270281------------- 
    271282 
    272 ``ORCA2_SAS_ICE`` is a demonstrator of the SAS ( Stand-alone Surface module ) based on ORCA2_LIM configuration. 
    273  
    274 The standalone surface module allows surface elements such as sea-ice, iceberg drift and surface fluxes to 
    275 be run using prescribed model state fields. 
    276 For example, it can be used to inter-compare different bulk formulae or adjust the parameters of 
    277 a given bulk formula 
    278  
    279 See `ORCA2_ICE_PISCES`_ for general description of ORCA2. 
    280  
    281 Same input files as `ORCA2_ICE_PISCES`_ are needed plus fields from a previous ORCA2_LIM run. 
    282  
    283 More informations on input and configuration files in `NEMO manual`_. 
     283ORCA2_SAS_ICE is a demonstrator of the Stand-Alone Surface (SAS) module and it relies on ORCA2 global ocean configuration (see `ORCA2_ICE_PISCES`_ for general description). 
     284 
     285The standalone surface module allows surface elements such as sea-ice, iceberg drift, and surface fluxes to be run using prescribed model state fields. 
     286It can profitably be used to compare different bulk formulae or adjust the parameters of a given bulk formula. 
     287 
     288More informations about SAS can be found in NEMO manual.
