There are numerous tools for pre-processing data, converting model |
| 10 |
|
|
output and analysis written in Matlab, fortran (f77 and f90) and perl. |
| 11 |
|
|
As yet they remain undocumented although many are self-documenting |
| 12 |
|
|
(Matlab routines have "help" written into them). |
| 13 |
|
|
|
| 14 |
|
|
Here we'll summarize what is available but this is an ever growing resource |
| 15 |
|
|
so this may not cover everything that is out there: |

\section{Utilities supplied with the model} |
| 18 |
|
|
|
| 19 |
|
|
We supply some basic scripts with the model to facilitate conversion or reading |
| 20 |
|
|
of data into analysis software. |

In the directory {\em utils/scripts} you will find {\em joinds} and {\em joinmds}: |
| 25 |
adcroft |
1.3 |
these are perl scripts used from joining the multi-part files created by |
| 26 |
|
|
MITgcm. {\bf Use {\em joinmds} always}. You will only need {\em joinds} if you |
| 27 |
|
|
are working with output older than two years (prior to c23). |
| 28 |
|
|
|
| 29 |
|
|
\subsection{utils/matlab} |
| 30 |
|
|
|
| 31 |
|
|
In the directory {\em utils/matlab} you will find several Matlab scripts |
| 32 |
|
|
(.m or dot-em files). The priniciple script is {\em rdmds.m} used for reading |
| 33 |
|
|
the multi-part model output files in to matlab. Place the scripts in your |
| 34 |
|
|
matlab path or change the path appropriately, then at the matlab prompt type: |
| 35 |
|
|
\begin{verbatim} |
| 36 |
|
|
>> help rdmds |
| 37 |
|
|
\end{verbatim} |
| 38 |
|
|
to get help on how to use rdmds. |
| 39 |
|
|
|
| 40 |
|
|
Another useful script scans the terminal output file for "monitor" information. |
| 41 |
|
|
|
| 42 |
|
|
Most other scripts are for working in the curvilinear coordinate systems which |
| 43 |
|
|
as yet are unpublished and undocumented. |
| 44 |

\section{Pre-processing software} |
| 46 |
|
|
|
| 47 |
|
|
There is a suite of pre-processing software for intepolating bathymetry |
| 48 |
|
|
and forcing data, written by Adcroft and Biastoch. At some point, |
| 49 |
|
|
these will be made available for download. If you are in need of such |
| 50 |
|
|
software, contact one of them. |
