- 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 ifenty 1.1 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 ifenty 1.4 #undef SEAICE_ALLOW_DYNAMICS
29 ifenty 1.1
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 jmc 1.6 #undef SEAICE_SIMPLIFY_GROWTH_ADJ
47 ifenty 1.1
48 gforget 1.9 C-- Since the missing sublimation term is now included
49     C this flag is needed for backward compatibility
50     #define SEAICE_DISABLE_SUBLIM
51 ifenty 1.1
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 gforget 1.9 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 ifenty 1.1
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 ifenty 1.2 #define SEAICE_VARIABLE_SALINITY
82 ifenty 1.1
83 jmc 1.6 #endif /* ALLOW_SEAICE */
84 ifenty 1.1 #endif /* SEAICE_OPTIONS_H */
