New URL for NEMO forge!   http://forge.nemo-ocean.eu

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.

Various corrections on chapters

Cleaning the indexes by fixing/removing wrong entries (or appending a ? to unknown items) and
improve the classification with new index definitions for CPP keys and namelist blocks:

  • from \key{...} cmd, key_ prefix no longer precedes the index entry
  • namelist block declaration moves from \ngn{nam...} to \nam{...} (i.e. \ngn{namtra\_ldf} -> \nam{tra\_ldf}) The expected prefix nam is added to the printed word but not the index entry.

Now we have indexes with a better sorting instead of all CPP keys under 'K' and namelists blocks under 'N'.

Fix missing space issues with alias commands by adding a trailing backslash (\NEMO\, \ie\, \eg\, ...).
There is no perfect solution for this, and I prefer not using a particular package to solve it.

Review the initial LaTeX code snippet for the historic changes in chapters

Finally, for readability and future diff visualisations, please avoid writing paragraphs with continuous lines.
Break the lines around 80 to 100 characters long

    2626These are read into the model from a NetCDF file which may be produced by separate data assimilation code. 
    2727The code can also output model background fields which are used as an input to data assimilation code. 
    28 This is all controlled by the namelist \textit{\ngn{nam\_asminc} }.

    102102It is quite challenging for data assimilation systems to provide non-divergent velocity increments. 
    103 Applying divergent velocity increments will likely cause spurious vertical velocities in the model. This section describes a method to take velocity increments provided to \NEMO ($u^0_I$ and $v^0_I$) and adjust them by the iterative application of a divergence damping operator. The method is also described in \citet{dobricic.pinardi.ea_OS07}.

    105105In iteration step $n$ (starting at $n=1$) new estimates of velocity increments $u^{n}_I$ and $v^{n}_I$ are updated by:

    135135Diffusion coefficients are defined as $A_D = \alpha e_{1t} e_{2t}$, where $\alpha = 0.2$.

    137137a value greater than zero. 
    138138This specifies the number of iterations of the divergence damping. Setting a value of the order of 100 will result in a significant reduction in the vertical velocity induced by the increments.
