- update CPPs and run time params (SEAICE_tempFrz0    = -1.96,
  SEAICE_dTempFrz_dS = 0., to use constant freezing point).
- no result chnages.

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-- Since the missing sublimation term is now included
49 C this flag is needed for backward compatibility
50 #define SEAICE_DISABLE_SUBLIM
51
52 C-- By default cdm wind stress under sea-ice is set to the
53 C same value as it would be if there was no sea-ice.
54 C This is a placeholder until a more physically-sensible
55 C stable solution is developed. Apparently ocean stress
56 C that is based on sea-ice velocity can cause trouble in
57 C Arctic Ocean configurations. This temporary solution
58 C also corresponds to that adopted by CCSM-2. For the
59 C adventurous user who requires ice-modified stress,
60 C following options are available.
61 #undef SEAICE_ORIGINAL_BAD_ICE_STRESS
62 #undef SEAICE_TEST_ICE_STRESS_1
63
64 C-- The freezing point of water is a simple linear dependence to salinity.
65 C The flag below is now obsolete, but kept to ease the transition
66 C from the old constant freezing point default (see seaice_check.F).
67 #define SEAICE_VARIABLE_FREEZING_POINT
68
69 C-- By default the seaice model is discretized on a B-Grid (for
70 C historical reasons). Define the following flag to use a new
71 C (not thoroughly) test version on a C-grid
72 #define SEAICE_CGRID
73
74 C-- Only for the C-grid version it is possible to enable EVP code by
75 C defining the following flag
76 #ifdef SEAICE_CGRID
77 #define SEAICE_ALLOW_EVP
78 #endif /* SEAICE_CGRID */
79
80 C-- By default sea ice is fresh. Set following flag for salty ice.
81 #define SEAICE_VARIABLE_SALINITY
82
83 #endif /* ALLOW_SEAICE */
84 #endif /* SEAICE_OPTIONS_H */
