Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

    104= '''PHC_9 run''' =  
    115This run is based on the PHC_8 one except on the way the wind stress and module are managed.[[BR]] 
    126Wind stress seems to be too low (in PHC_8) in high latitudes compared to what we have in using standard [[BR]] 
    13 CLIO data this component is capital for the water mass formation & penetration in these areas so it must be increased. 
     7CLIO data this component is capital for the water mass formation & penetration in these areas so it must be increased.[[BR]] 
    148So we do the following test:[[BR]] 
    15 - compute off-line the daily climatology of the fields (||U||.u)clim and (||U||.v)clim using 6hourly wind velocities.[[BR]] 
     9- compute off-line the daily climatology of the fields (wndm.u)clim and (wndm.v)clim using 6hourly wind velocities.[[BR]] 
    1610- we use the wind module computed with the 6hourly wind velocities which is much more energetics than the one computed using climatological velocities.[[BR]]
