    2524The current zdfiwm.F90 (internal wave driven mixing) routine was coded prior to the CMIP6 exercise, as documented in chapter 5 of my PhD thesis (​https://tel.archives-ouvertes.fr/tel-01592475). A refined version has been published since (​https://doi.org/10.1029/2020MS002065). This refined version is simpler and has been thoroughly validated against observations.

    3330Only the zdfiwm.F90 routine is modified. \\ 
    3431One namelist parameter in namzdf_iwm is removed ('nn_zpyc'). There are no new namelist parameters, but there is a new forcing file. This file is called 'zdfiwm_forcing.nc' and contains six variables to be read: power_cri, power_bot, power_nsq, power_sho, scale_cri, scale_bot.\\

    42 Using previous parts, define the main changes to be done in the NEMO literature  
    43 (manuals, guide, web pages, …). 
    44 }}} 
     37Section 9.5 (Internal-wave-driven mixing) of the NEMO-OCE manual needs to be modified. The overall approach has not changed, only the number of input fields and the details of vertical structures. One namelist parameter has been removed. 
     38 
     39As for webpages, the only important change is in the forcing file(s) for internal-wave-driven mixing provided to users and developers of realistic configurations. The new forcing file is provided on ORCA2, ORCA1 and regular grids. For simulations at resolution finer than 1 degree, the file on the regular latitude-longitude grid must first be interpolated onto the employed grid.
