    1616Basic NEMO model configuration is described in Oddo et al. 2009. Model domain covers the whole Mediterranean Sea plus a “large” Atlantic box, where the model is nested with the Global ¼ Degree MERCATOR operational model. External Lateral Open Boundary Condition data are monthly climatology obtained from 10 year global experiment.  
    1717The main difference with standard NEMO code concerns the volume conservation. In Standard OPA code, in case of filtered free surface option, the volume conservation is imposed. In the present version of the model the Mass/Volume transport across the model domain lateral open boundaries is driven by a generalized Flather’s algoritm (Oddo et al. 2008) see eq. 3 in Odo et al 2010. 
    18 Four different experiment have been performed in order to understand the differences in using the Atmospherci pressure forcing in case of time-splitting and filtered free surface formulation. 
    19 EXP1 reproduces the Oddo et al 2010, experiment with NEMO_3.3.1, so it has the filtered free surface formulation and no atmospheric pressure (AP) 
    20 EXP2 is the same of EXP1 plus the introduction of the AP. 
    21 EXP3 is the same model step-up of EXP1 but with time-splitting option. 
    22 EXP4 is EXP3 plus the introduction of the AP forcing.
