c |
| 13 |
2. Enable inclusion of atmospheric fields |
c 1. 'No forcing' should be possible for each field type, |
| 14 |
as part of the control vector. |
c e.g., by leaving file name blank. |
| 15 |
|
c |
| 16 |
|
c 2. Cyclic forcing should be available for each field type |
| 17 |
|
c (surface forcing and relaxation to climatology). |

|
c Many assumptions that are made in the current version should, and |
| 23 |
|
c can, be relaxed in later versions: |
| 24 |
|
c |
| 25 |
|
c - There is an inconsistency in the formulation of forcing variables |
| 26 |
|
c defined on southern and western points on the C-grid, since the |
| 27 |
|
c the atmospheric stability is calculated on center points of the |
| 28 |
|
c C-grid. |

|
c - gridded data sets --> general data set (other grids, inter- |
| 31 |
|
c polation in space) |
| 32 |
|
c |
| 33 |
|
c - equidistancy in time --> general data set (non-equidistant in |
| 34 |
|
c time) |
| 35 |
|
c |
| 36 |
|
c - climatologies --> arbitrary subinterval of a year, not |
| 37 |
|
c just monthly values. |
| 38 |
|
c |
| 39 |
|
c - relaxation --> relaxation could be done to a given |
| 40 |
|
c data set over the model's integration |
| 41 |
|
c time. This would generalise the clima- |
| 42 |
|
c tology block. One could have 'cyclic' |
| 43 |
|
c and 'non-cyclic' fields. In the first |
| 44 |
|
c case, the cycle length has to be spe- |
| 45 |
|
c cified ('monthly','yearly','period') as |
| 46 |
|
c well as the start of the cycle ( irec=1 |
| 47 |
|
c corresponds to a certain calendar date). |
| 48 |
|
c The second case can be treated analog- |
| 49 |
|
c ously. |
