NEMO vertical grid

I would like to create a vertical partial grid (z-coordinate - partial steps) of 75 levels with a very high resolution in the layer 30-100 m (with level thickness about 2 m).
Which values should be used for the coefficients ppsur, ppa0, ppa1, ppkth, ppdzmin, pphmax ?
Is there any recommendations ?

I’m not sure about the answer, but I remember one thing from experience: the difference of thickness between two neighbouring vertical cells should not exceed 10% (or even less, do check in the Nemo manual).
