The parameterization of the ocean skin of Bellenger et al. (2017) can be activated by setting: activate_ocean_skin = 1 or 2 in physiq.def. The default value is 0 (parameterization not activated). If activate_ocean_skin = 1 then the parameterization is activated in diagnostic mode only: it has no retroaction on LMDZ. If activate_ocean_skin = 2 then the parameterization is activated with retroaction on LMDZ. | The parameterization of the ocean skin of Bellenger et al.

Some additional NetCDF variables can be output in history files when the parameterization is activated:
- ds_ns: subskin salinity minus foundation salinity, in ppt
- dt_ns: subskin temperature minus foundation temperature, in K
- s_int: interface salinity, in ppt
- t_int: interface temperature, in K
- dter: ocean-air interface temperature minus subskin temperature, in K
- dser: ocean-air interface salinity minus subskin salinity, in ppt
- tkt: thickness of cool skin (microlayer), in m
- tks: thickness of mass diffusion layer (microlayer), in m
- taur: momentum flux due to rain, in Pa
- delta_SST: ocean-air interface temperature minus bulk SST, in K
- delta_sal: ocean-air interface salinity minus bulk salinity, in ppt
- SSS: bulk sea-surface salinity, in ppt
