    6161The water column setup, called NEMO1D, is activated with the inclusion of the CPP key ``key_c1d`` and has a horizontal domain of 3x3 grid points. 
    6262 
    63 This reference configuration uses 75 vertical levels grid (1m at the surface), GLS turbulence scheme with K-epsilon closure and the CORE Bulk formulae.

    9494Note that, the default grid size is 30x20 grid points (with ``nn_GYRE = 1``) and vertical levels are set by ``jpkglo``.

    96 **Running GYRE as a benchmark** :  this simple configuration can be used as a benchmark since it is easy to increase resolution, with the drawback of getting results that have a very limited physical meaning (see e.g., `Levy et al 2010 <https://www.sciencedirect.com/science/article/pii/S1463500310000582>`_). 
    97  
    98 GYRE grid resolution can be easily increased at runtime by setting a different value of ``nn_GYRE`` that is an integer multiplier factor to scale the grid size,  as described in the following table:

    110110Note that,  it is necessary to set ``ln_bench = .true.`` in ``namusr_def`` to avoid problems in the physics computation and that the model timestep should be adequately rescaled.

    112 For example if ``nn_GYRE = 150``, that is equivalent to ORCA 1/12° the timestep should be set to 1200 seconds

    210 ``ORCA2_OFF_PISCES`` uses the ORCA2 configuration in which the `PISCES biogeochemical model`_ has been activated in 
    211 standalone using the dynamical fields that are pre calculated. 
    212  
    213 See `ORCA2_ICE_PISCES`_ for general description of ORCA2. 
    214  
    215 The input files for PISCES are needed, in addition the dynamical fields are used as input. 
    216 They are coming from a 2000 years of an ORCA2_LIM climatological run using ERA40 atmospheric forcing. 
     210ORCA2_OFF_PISCES  shares the same general configuration of ORCA2_ICE_PISCES, but dynamical fields are pre-calculated and stored with 5 days frequency. 
     211This enables for an offline coupling of all TOP components, here specifically dealing with PISCES biogeochemical model. 
     212 
     213Pre-calculated dynamical fields are provided to NEMO using the namelist ``&namdta_dyn``  in ``namelist_cfg`` :
