The MITgcm has several packages that are related to the output |
| 13 |
|
|
produced during a model integration that is used for analysis |
| 14 |
|
|
of the results. The packages are related to the choice of output |
| 15 |
|
|
fields and to the format of the model output. |

\section{Pre- and Post- Processing Scripts and Utilities} |

1.3 |
There are numerous tools for pre-processing data, converting model |
| 36 |
|
|
output and analysis written in Matlab, fortran (f77 and f90) and perl. |
| 37 |
|
|
As yet they remain undocumented although many are self-documenting |
| 38 |
|
|
(Matlab routines have "help" written into them). |
| 39 |
|
|
|
| 40 |
|
|
Here we'll summarize what is available but this is an ever growing resource |
| 41 |
|
|
so this may not cover everything that is out there: |

\subsection{Utilities supplied with the model} |
| 44 |
adcroft |
1.3 |
|
| 45 |
|
|
We supply some basic scripts with the model to facilitate conversion or reading |
| 46 |
|
|
of data into analysis software. |

1.4 |
In the directory {\em utils/scripts} you will find {\em joinds} and {\em joinmds}: |
| 51 |
adcroft |
1.3 |
these are perl scripts used from joining the multi-part files created by |
| 52 |
|
|
MITgcm. {\bf Use {\em joinmds} always}. You will only need {\em joinds} if you |
| 53 |
|
|
are working with output older than two years (prior to c23). |

\subsubsection{utils/matlab} |
| 56 |
adcroft |
1.3 |
|
| 57 |
|
|
In the directory {\em utils/matlab} you will find several Matlab scripts |
| 58 |
|
|
(.m or dot-em files). The priniciple script is {\em rdmds.m} used for reading |
| 59 |
|
|
the multi-part model output files in to matlab. Place the scripts in your |
| 60 |
|
|
matlab path or change the path appropriately, then at the matlab prompt type: |
| 61 |
|
|
\begin{verbatim} |
| 62 |
|
|
>> help rdmds |
| 63 |
|
|
\end{verbatim} |
| 64 |
|
|
to get help on how to use rdmds. |
| 65 |
|
|
|
| 66 |
|
|
Another useful script scans the terminal output file for "monitor" information. |
| 67 |
|
|
|
| 68 |
|
|
Most other scripts are for working in the curvilinear coordinate systems which |
| 69 |
|
|
as yet are unpublished and undocumented. |

\subsection{Pre-processing software} |
| 72 |
adcroft |
1.3 |
|
| 73 |
|
|
There is a suite of pre-processing software for intepolating bathymetry |
| 74 |
|
|
and forcing data, written by Adcroft and Biastoch. At some point, |
| 75 |
|
|
these will be made available for download. If you are in need of such |
| 76 |
|
|
software, contact one of them. |
