c Selection of forcing fields |
| 5 |
c |
| 6 |
c 1. Cyclic forcing should be available for each field type |
| 7 |
c (surface forcing and relaxation to climatology). |
| 8 |
c |
| 9 |
c Cleaning package |
| 10 |
c |
| 11 |
c 1. Reduce number of subroutines. |
| 12 |
c |
| 13 |
c 2. - Separate routine for bulk formulae exf_bulk_formulae |
| 14 |
c - Atmospheric control to exf_getsurfacefluxes |
| 15 |
- Calling tree will look like this: |
| 16 |
c exf_getforcing |
| 17 |
c |-- exf_getclim |
| 18 |
c |-- exf_getffields |
| 19 |
c |-- exf_getsurfacefluxes |
| 20 |
c |-- exf_bulk_formulae |
| 21 |
c |-- exf_mapfields |
| 22 |
c |
| 23 |
c Many assumptions that are made in the current version should, and |
| 24 |
c can, be relaxed in later versions: |
| 25 |
c |
| 26 |
c - There is an inconsistency in the formulation of forcing variables |
| 27 |
c defined on southern and western points on the C-grid, since the |
| 28 |
c the atmospheric stability is calculated on center points of the |
| 29 |
c C-grid. Also need to make sure that with options EXFwindOnBgrid |
| 30 |
c and/or SEAICEwindOnCgrid set, wind and wind stress is interpolated |
| 31 |
c to correct grid location. |
| 32 |
c |
| 33 |
c - gridded data sets --> general data set (other grids, inter- |
| 34 |
c polation in space) |
| 35 |
c |
| 36 |
c - equidistancy in time --> general data set (non-equidistant in |
| 37 |
c time) |
| 38 |
c |
| 39 |
c - climatologies --> arbitrary subinterval of a year, not |
| 40 |
c just monthly values. |
| 41 |
c |
| 42 |
c - relaxation --> relaxation could be done to a given |
| 43 |
c data set over the model's integration |
| 44 |
c time. This would generalise the clima- |
| 45 |
c tology block. One could have 'cyclic' |
| 46 |
c and 'non-cyclic' fields. In the first |
| 47 |
c case, the cycle length has to be spe- |
| 48 |
c cified ('monthly','yearly','period') as |
| 49 |
c well as the start of the cycle ( irec=1 |
| 50 |
c corresponds to a certain calendar date). |
| 51 |
c The second case can be treated analog- |
| 52 |
c ously. |
