\subsection{Model initialization (./src/TOP/trcini.F90)}
This module consists on inital set up of passive tracers variables and parameters : read the namelist, set initial tracer fields (either read restart or read data or analytical formulation and specific initailisation in each SMS module ( analytical initialisation of tracers or constant values )
\begin{minted}{bash}

\section{Coupling an external BGC model using NEMO framework}
The coupling with an external BGC model through the NEMO compilation framework can be achieved in different ways according to the degree of coding complexity of the Biogeochemical model, like e.g., the whole code is made only by one file or it has multiple modules and interfaces spread across several subfolders.\\ \\
Beside the 6 core files of MY\_TRC module, see (see \label{Mytrc}, let's assume an external BGC model named \textit{"MYBGC"} and constituted by a rather essential coding structure, likely few Fortran files. The new coupled configuration name is NEMO\_MYBGC. \\ \\
The best solution is to have all files (the modified MY\_TRC routines and the BGC model ones) placed in a unique folder with root \path{<MYBGCPATH>} and to use the \textit{makenemo} external readdressing of MY\_SRC folder. \\ \\
The coupled configuration listed in \textbf{cfg.txt} will look like
\begin{minted}{bash}
NEMO_MYBGC OPA_SRC TOP_SRC
\end{minted}
and the related cpp\_MYBGC.fcm content will be
%
\begin{minted}{bash}
bld::tool::fppkeys key_xios key_top
\end{minted}
The compilation with \textit{makenemo} will be executed through the following syntax
\begin{minted}{bash}
makenemo -n NEMO_MYBGC -m <arch_my_machine> -j 8 -e <MYBGCPATH>
\end{minted}
The makenemo feature \textit{-e} was introduced to readdress at compilation time the standard MY\_SRC folder (usually found in NEMO configurations) with a user defined external one. \\ \\
The compilation of more articulated BGC model code \& infrastructure, like in the case of BFM (BFM-NEMO coupling manual), requires some additional features. \\ \\
As before, let's assume a coupled configuration name NEMO\_MYBGC, but in this case MYBGC model root becomes <MYBGCPATH> that contains 4 different subfolders for biogeochemistry, named initialization, pelagic, and benthic, and a separate one named nemo\_coupling including the modified MY\_SRC routines. The latter folder containing the modified NEMO coupling interface will be still linked using the makenemo \textit{-e} option. \\ \\
In order to include the BGC model subfolders in the compilation of NEMO code, it will be necessary to extend the configuration \textit{cpp\_NEMO\_MYBGC.fcm} file to include the specific paths of MYBGC folders, as in the following example
\begin{minted}{bash}
bld::tool::fppkeys key_xios key_top
src::MYBGC::initialization <MYBGCPATH>/initialization
src::MYBGC::pelagic <MYBGCPATH>/pelagic

Note that, the additional lines specific for the BGC model source and build paths, can be written into a separate file, e.g. named MYBGC.fcm, and then simply included in the cpp\_NEMO\_MYBGC.fcm as follow:
\begin{minted}{bash}
bld::tool::fppkeys key_zdftke key_dynspg_ts key_xios key_top

Important: the coupling interface contained in nemo\_coupling cannot be added using the FCM syntax, as the same files already exists in NEMO and they are overridden only with the readdressing of MY\_SRC contents to avoid compilation conflicts due to duplicate routines. \\ \\
All modifications illustrated above, can be easily implemented using shell or python scripting to edit the NEMO configuration cpp.fcm file and to create the BGC model specific FCM compilation file with code paths.

\section{Coupling an external BGC model using NEMO framework}
The coupling with an external BGC model through the NEMO compilation framework can be achieved in different ways according to the degree of coding complexity of the Biogeochemical model, like e.g., the whole code is made only by one file or it has multiple modules and interfaces spread across several subfolders.\\ \\
Beside the 6 core files of MY\_TRC module, see (see \label{Mytrc}, let's assume an external BGC model named \textit{"MYBGC"} and constituted by a rather essential coding structure, likely few Fortran files. The new coupled configuration name is NEMO\_MYBGC. \\ \\
The best solution is to have all files (the modified MY\_TRC routines and the BGC model ones) placed in a unique folder with root \path{<MYBGCPATH>} and to use the \textit{makenemo} external readdressing of MY\_SRC folder. \\ \\
Before compiling the code it is necessary to create the new configuration folder
\begin{minted}{bash}
$[nemo-code-root]> mkdir cfgs/NEMO_MYBGC
\end{minted}
and add in it the configuration file cpp\_MYBGC.fcm whose content will be
\begin{minted}{bash}
bld::tool::fppkeys key_xios key_top
\end{minted}
The compilation with \textit{makenemo} will be executed through the following syntax, by including OCE and TOP components
\begin{minted}{bash}
$[nemo-code-root]> ./makenemo -r GYRE_PISCES -n NEMO_MYBGC -d "OCE TOP" -m <arch_my_machine> -j 8 -e <MYBGCPATH>
\end{minted}
The makenemo feature \textit{-e} was introduced to readdress at compilation time the standard MY\_SRC folder (usually found in NEMO configurations) with a user defined external one.
After the compilation, the coupled configuration will be listed in \textbf{work\_cfg.txt} and it will look like
\begin{minted}{bash}
NEMO_MYBGC OCE TOP
\end{minted}
The compilation of more articulated BGC model code \& infrastructure, like in the case of BFM \citep{bfm_nemo_coupling}, requires some additional features. \\
As before, let's assume a coupled configuration name NEMO\_MYBGC, but in this case MYBGC model root becomes <MYBGCPATH> that contains 4 different subfolders for biogeochemistry, named initialization, pelagic, and benthic, and a separate one named nemo\_coupling including the modified MY\_SRC routines. The latter folder containing the modified NEMO coupling interface will be still linked using the makenemo \textit{-e} option. \\
In order to include the BGC model subfolders in the compilation of NEMO code, it will be necessary to extend the configuration \textit{cpp\_NEMO\_MYBGC.fcm} file to include the specific paths of MYBGC folders, as in the following example
\begin{minted}{bash}
bld::tool::fppkeys key_xios key_top
src::MYBGC::initialization <MYBGCPATH>/initialization
src::MYBGC::pelagic <MYBGCPATH>/pelagic
src::MYBGC::benthic <MYBGCPATH>/benthic
bld::pp::MYBGC 1
bld::tool::fppflags::MYBGC \%FPPFLAGS

\end{minted}
where MYBGC\_MACROS is the space delimited list of macros used in MYBGC model for selecting/excluding specific parts of the code. The BGC model code will be preprocessed in the configuration BLD folder as for NEMO, but with an independent path, like NEMO\_MYBGC/BLD/MYBGC/<subfolders>.\\

\chapter{TOP structure and workflow}
\label{chap:ModDes}
TOP is the NEMO hardwired interface toward biogeochemical models, which provides the physical constraints/boundaries for oceanic tracers (Fig. ~\ref{fig:topstructure}).
Based on a modular structure, this component allows one to exploit available built-in modules and further develop a range of applications, spanning from the implementation of a dye passive tracer to evaluate dispersion processes (by means of MY\_TRC), track water masses age (AGE module), assess the ocean interior penetration of persistent chemical compounds (e.g., gases like CFC or even PCBs), up to the full set of equations to simulate marine biogeochemical cycles.
TOP interface has the following location in the code repository : \path{<nemo-repository>/src/TOP/}
and the following modules are available:
%----------- tableau ------------------------------------
\begin{itemize}
\item \textbf{TRP} : Interface to NEMO physical core for computing tracers transport
\item \textbf{CFC} : Inert tracers (CFC11,CFC12, SF6)
\item \textbf{C14} : Radiocarbon passive tracer
\item \textbf{AGE} : Water age tracking
\item \textbf{MY\_TRC} : Template for creation of new modules and external BGC models coupling
\item \textbf{PISCES} : Built in BGC model. See \cite{aumont_2015} for a complete description
\end{itemize}

The workflow of the TOP interface within the NEMO framework is organized around two main blocks of the code, the initialization (\autoref{fig:topinit}) and time marching or "stepping" (\autoref{fig:topstep}) procedures.\\
The initialization (\forcode{trc_init}) of passive tracers variables and parameters include reading namelist, set initial tracer fields (either read restart or read data), and specific initialisation for each SMS module.

In the time-marching procedure of the model (trc\_stp), trends are computed for all tracers in relation to biogeochemical processes (source minus sinks of each TOP sub-module),
physical transport (advective \& diffusive, forcing and boundary conditions) and output is managed using the I/O library XIOS.
