checkpoint50g_post
o merged with release1_p17 (pkg/seaice and verification/lab_sea)
  - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
  - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
    made the default because of faster convergence than ADI

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     #undef SEAICE_EXTERNAL_FORCING
33    
34     C-- By default, the sea-ice package uses its own integrated bulk
35     C formulae to compute fluxes (fu, fv, EmPmR, Qnet, and Qsw) over
36     C open-ocean. When this flag is set, these variables are computed
37     C in a separate external package, for example, pkg/exf, and then
38     C modified for sea-ice effects by pkg/seaice.
39     #undef SEAICE_EXTERNAL_FLUXES
40 heimbach 1.2
41 dimitri 1.5 C-- By default, the sea-ice package uses 2-category thermodynamics.
42     C When this flag is set, an 8-category calculation of ice
43     C thermodynamics is carried out in groatb.F
44     #undef SEAICE_MULTILEVEL

46 dimitri 1.4 #endif /* ALLOW_SEAICE */
