    68    The current version in MICT works (couple and force mode) but is not fully implicit and the energy conservation at each time step should be checked!  
    79    The work to make it fully implicit needs to be quantified with Tao (Anticipated to be relatively straightforward) 
    8   - Eventually implement a soil freezing for the "thin layers of the new vertical discretization" => ?? 
    9     A solution to avoid large oscillations needs to be proposed and tested.

    4646  - We then further add a fractional snow cover so that the problem of "very thin" snow layer (linked to the non fully implicit scheme) becomes most likely negligeable. FOR THAT, we need to start an email discussion about the requested changes (how does it change the call sequences to "thermosoil" and "ES" ?): Anyone is wellcome to launch the email discussion. Then, JLD propose that Fuxing helps with this implementation but other organizations are possible.  
    4747  - Few persons needs to gather to establish properly the equation-changes that are needed for a full implicit implementation between "enerbyl" "ES" and "Thermosoil": the list of the "few" needs to be decided ? (volunter ?) 
    48  - Soil freezing 
    49   - We start for CMIP6 with the current scheme of Isabelle G. 
    50   - GK/PP will ask IG if she wants to further work on improving the scheme (given that she is working a bit with ORC) with the objective of energy conservation per layer and not only over the whole year; Other person to work on it are welcome!
