 o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
   not mnc -- this mistake was found by JMC and is now corrected

11 edhill 1.7 #ifndef SEAICE_OPTIONS_H
12     #define SEAICE_OPTIONS_H
13     #include "PACKAGES_CONFIG.h"
14 heimbach 1.2 #include "CPP_OPTIONS.h"
15    
16 dimitri 1.3 C-- Write "text-plots" of certain fields in STDOUT for debugging.
17 heimbach 1.2 #undef SEAICE_DEBUG
18    
19 dimitri 1.3 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 heimbach 1.2 #define SEAICE_ALLOW_DYNAMICS
25 dimitri 1.3
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 dimitri 1.9 #define SEAICE_EXTERNAL_FORCING
33 dimitri 1.8 #ifdef SEAICE_EXTERNAL_FORCING
34     #include "EXF_OPTIONS.h"
35     #endif /* SEAICE_EXTERNAL_FORCING */
36 dimitri 1.3
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 dimitri 1.9 #define SEAICE_EXTERNAL_FLUXES
43 heimbach 1.2
44 dimitri 1.5 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 dimitri 1.10 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 dimitri 1.5 #undef SEAICE_MULTILEVEL
52    
53 dimitri 1.10 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 edhill 1.7 #endif /* SEAICE_OPTIONS_H */
