12 | The usage of TOP is activated |
---|
13 | |
---|
14 | \begin{itemize} |
---|
15 | \item by including in the configuration definition the component TOP\_SRC |
---|
16 | \item by adding the macro \textit{key\_top} in the configuration cpp file |
---|
17 | \end{itemize} |
---|
18 | |
---|
19 | As an example, the user can refer to already available configurations in the code, GYRE\_PISCES being the NEMO biogeochemical demonstrator and GYRE\_BFM to see the required configuration elements to couple with an external biogeochemical model (see also section \S\ref{SMS_models}) . |

---|
21 | Note that, since version 4.0, TOP interface core functionalities are activated by means of logical keys and all submodules preprocessing macros from previous versions were removed. |
---|
22 | |
---|
23 | There are only three specific keys remaining in TOP |
---|
24 | |
---|
25 | \begin{itemize} |
---|
26 | \item \textit{key\_top} : to enables passive tracer module |
---|
27 | \item \textit{key\_trdtrc} and \textit{key\_trdmxl\_trc} : trend computation for tracers |
---|
28 | \end{itemize} |
---|
29 | |
---|
30 | For a remind, the revisited structure of TOP interface now counts for five different modules handled in namelist\_top : |
---|
31 | |
---|
32 | \begin{itemize} |
---|
33 | \item \textbf{PISCES}, default BGC model |
---|
34 | \item \textbf{MY\_TRC}, template for creation of new modules couplings (maybe run a single passive tracer) |
---|
35 | \item \textbf{CFC}, inert carbon tracers dynamics (CFC11,CFC12,SF6) Updated with OMIP-BGC guidelines (Orr et al, 2016) |
---|
36 | \item \textbf{C14}, radiocarbon passive tracer |
---|
37 | \item \textbf{AGE}, water age tracking revised implementation |
---|
38 | \end{itemize} |
---|
39 | |
---|
40 | The modular approach was implemented also in the definition of the total number of passive tracers (jptra). This results from to user setting from the namelist \textit{namtrc} |
