% Descripton: |
| 25 |
|
|
% This function loads MNC data. The field to load is defined by 'fln'. |
| 26 |
|
|
% Typically, whatever 'fln' is set to is the fields that is read in, |
| 27 |
|
|
% though the AIM physics parameters in a noteable exception to this. The |
| 28 |
|
|
% data must be all located in the folder specified by 'dad', and this |
| 29 |
|
|
% string must end with a '/', and similarly for the grid data. |

|
% Generally, the data is read in by using the 'rdmds' function (see MITgcm) |
| 41 |
|
|
% with FNAME as [fln,filesuffix], and ITER = iter. There are some |
| 42 |
|
|
% exceptions, such as the AIM physics parameters. Some of the fields then |
| 43 |
|
|
% require some immediate manipulation. Examples are U (instantaneous) and |
| 44 |
|
|
% uVel (time-averaged) which are immediately converted to a lat-lon grid |
| 45 |
|
|
% because the 'U' and 'V' files of the cube-sphere do NOT correspond to the |
| 46 |
|
|
% typical zonal and meridional winds. Some other fields, such as 'KEpri' |
| 47 |
|
|
% require some simple calculations which are immediately done. |
