C-- Write "text-plots" of certain fields in STDOUT for debugging. |

#undef SEAICE_DEBUG |

C-- Allow sea-ice dynamic code. |
| 20 |
C This option is provided to allow use of TAMC |
| 21 |
C on the thermodynamics component of the code only. |
| 22 |
C Sea-ice dynamics can also be turned off at runtime |
| 23 |
C using variable SEAICEuseDYNAMICS. |
| 24 |
#define SEAICE_ALLOW_DYNAMICS |
| 25 |
|
| 26 |
C-- By default, pkg/seaice defines forcing variable internally, in |
| 27 |
C SEAICE_FFIELDS.h, and reads them in from files. When CPP option |
| 28 |
C SEAICE_EXTERNAL_FORCING is defined, the above forcing variables |
| 29 |
C are defined and provided by an external package. At present this |
| 30 |
C option is hardwired for pkg/exf and the variables are passed using |
| 31 |
C include file exf_fields.h. |
| 32 |
#define SEAICE_EXTERNAL_FORCING |
| 33 |
#ifdef SEAICE_EXTERNAL_FORCING |
| 34 |
#include "EXF_OPTIONS.h" |

#endif /* SEAICE_EXTERNAL_FORCING */ |
| 36 |
|
| 37 |
C-- By default, the sea-ice package uses its own integrated bulk |
| 38 |
C formulae to compute fluxes (fu, fv, EmPmR, Qnet, and Qsw) over |
| 39 |
C open-ocean. When this flag is set, these variables are computed |
| 40 |
C in a separate external package, for example, pkg/exf, and then |
| 41 |
C modified for sea-ice effects by pkg/seaice. |
| 42 |
#define SEAICE_EXTERNAL_FLUXES |
| 43 |
|
| 44 |
C-- By default, the sea-ice package uses 2-category thermodynamics. |
| 45 |
C When this flag is set, an 8-category calculation of ice |
| 46 |
C thermodynamics is carried out in groatb.F |
| 47 |
C Note the pickup_seaice.* generated by this option differ |
| 48 |
C from those generated with the default 2-category model. |
| 49 |
C Therefore it is not possible to switch between the two |
| 50 |
C in the middle of an integration. |
| 51 |
#undef SEAICE_MULTILEVEL |
| 52 |
|
| 53 |
C-- By default cdm wind stress under sea-ice is set to the |
| 54 |
C same value as it would be if there was no sea-ice. |
| 55 |
C This is a placeholder until a more physically-sensible |
| 56 |
C stable solution is developed. Apparently ocean stress |
| 57 |
C that is based on sea-ice velocity can cause trouble in |
| 58 |
C Arctic Ocean configurations. This temporary solution |
| 59 |
C also corresponds to that adopted by CCSM-2. For the |
| 60 |
C adventurous user who requires ice-modified stress, |
| 61 |
C following options are available. |
| 62 |
#undef SEAICE_ORIGINAL_BAD_ICE_STRESS |
| 63 |
#undef SEAICE_TEST_ICE_STRESS_1 |
| 64 |
|
| 65 |
#endif /* SEAICE_OPTIONS_H */ |
