18 C Package-specific Options & Macros go here
19
20 C-- Write "text-plots" of certain fields in STDOUT for debugging.
21 #undef SEAICE_DEBUG
22
23 C-- Allow sea-ice dynamic code.
24 C This option is provided to allow use of TAMC
25 C on the thermodynamics component of the code only.
26 C Sea-ice dynamics can also be turned off at runtime
27 C using variable SEAICEuseDYNAMICS.
28 #undef SEAICE_ALLOW_DYNAMICS
29
30 C-- By default, the sea-ice package uses its own integrated bulk
31 C formulae to compute fluxes (fu, fv, EmPmR, Qnet, and Qsw) over
32 C open-ocean. When this flag is set, these variables are computed
33 C in a separate external package, for example, pkg/exf, and then
34 C modified for sea-ice effects by pkg/seaice.
35 #define SEAICE_EXTERNAL_FLUXES
36
37 C-- By default, the sea-ice package uses 2-category thermodynamics.
38 C When this flag is set, an 8-category calculation of ice
39 C thermodynamics is carried out in groatb.F
40 C Note the pickup_seaice.* generated by this option differ
41 C from those generated with the default 2-category model.
42 C Therefore it is not possible to switch between the two
43 C in the middle of an integration.
44 #undef SEAICE_MULTICATEGORY
45 #undef SEAICE_MODIFY_GROWTH_ADJ
46 #undef SEAICE_SIMPLIFY_GROWTH_ADJ
47
48 c Use the McPhee Ocean-Ice heat flux
49 #define MCPHEE_OCEAN_ICE_HEAT_FLUX
50 #define GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
51
52 #define SEAICE_DO_OPEN_WATER_GROWTH
53 #define SEAICE_DO_OPEN_WATER_MELT
54
55 #define FENTY_AREA_EXPANSION_CONTRACTION
56
57 #undef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
58
59 C-- By default cdm wind stress under sea-ice is set to the
60 C same value as it would be if there was no sea-ice.
61 C This is a placeholder until a more physically-sensible
62 C stable solution is developed. Apparently ocean stress
63 C that is based on sea-ice velocity can cause trouble in
64 C Arctic Ocean configurations. This temporary solution
65 C also corresponds to that adopted by CCSM-2. For the
66 C adventurous user who requires ice-modified stress,
67 C following options are available.
68 #undef SEAICE_ORIGINAL_BAD_ICE_STRESS
69 #undef SEAICE_TEST_ICE_STRESS_1
70
71 C-- By default the freezing point of water is set to the value of
72 C the parameter SEAICE_freeze (=-1.96 by default). To use a
73 C simple linear dependence of the freezing point on salinity,
74 C set the following flag (pressure is assumed to have no effect,
75 C which is a good assumption for the top 20 meters). With this
76 C option defined the parameter SEAICE_freeze has no effect.
77 #undef SEAICE_VARIABLE_FREEZING_POINT
78
79 C-- By default the seaice model is discretized on a B-Grid (for
80 C historical reasons). Define the following flag to use a new
81 C (not thoroughly) test version on a C-grid
82 #define SEAICE_CGRID
83
84 C-- Only for the C-grid version it is possible to enable EVP code by
85 C defining the following flag
86 #ifdef SEAICE_CGRID
87 #define SEAICE_ALLOW_EVP
88 #endif /* SEAICE_CGRID */
89
90 C-- Seaice flooding
91 #define ALLOW_SEAICE_FLOODING
92
93 C-- By default sea ice is fresh. Set following flag for salty ice.
94 #define SEAICE_VARIABLE_SALINITY
95
96 c-- Enable modified sea-ice thermodynamic by Ian Fenty
97 c-- Should improve adjoint, but doesnt work so far.
98 #undef SEAICE_ALLOW_TD_IF
99
100 #endif /* ALLOW_SEAICE */
101 #endif /* SEAICE_OPTIONS_H */
