16
17 #ifdef ALLOW_SEAICE
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 #define 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-- The actual number of ice categories used to solve for seaice flux is
38 C now a run-time parameter (SEAICE_multDim).
39 C This CPP-flag will be completely removed soon (no longer in main code);
40 C it is just used to set default number of categories, i.e., =1 if undef,
41 C or =MULTDIM if defined (MULTDIM=7 in default SEAICE_SIZE.h).
42 C Note: be aware of pickup_seaice.* compatibility issues when restarting
43 C a simulation with a different number of categories.
44 c#define SEAICE_MULTICATEGORY
45
46 C-- Since the missing sublimation term is now included
47 C this flag is needed for backward compatibility
48 #undef SEAICE_DISABLE_SUBLIM
49
50 C-- Suspected missing term in coupled ocn-ice heat budget (to be confirmed)
51 #undef SEAICE_DISABLE_HEATCONSFIX
52
53 C-- Default is constant seaice salinity (SEAICE_salt0); Define the following
54 C flag to consider (space & time) variable salinity: advected and forming
55 C seaice with a fraction (=SEAICE_saltFrac) of freezing seawater salinity.
56 C- Note: SItracer also offers an alternative way to handle variable salinity.
57 #undef SEAICE_VARIABLE_SALINITY
58
59 C-- Tracers of ice and/or ice cover.
60 #undef ALLOW_SITRACER
61 #ifdef ALLOW_SITRACER
62 C-- To try avoid 'spontaneous generation' of tracer maxima by advdiff.
63 # define ALLOW_SITRACER_ADVCAP
64 #endif
65
66 C-- By default the seaice model is discretized on a B-Grid (for
67 C historical reasons). Define the following flag to use a new
68 C (not thoroughly) test version on a C-grid
69 #define SEAICE_CGRID
70
71 C-- Only for the C-grid version it is possible to
72 #ifdef SEAICE_CGRID
73 C enable EVP code by defining the following flag
74 # undef SEAICE_ALLOW_EVP
75 # ifdef SEAICE_ALLOW_EVP
76 C-- When set use SEAICE_zetaMin and SEAICE_evpDampC to limit viscosities
77 C from below and above in seaice_evp: not necessary, and not recommended
78 # undef SEAICE_ALLOW_CLIPZETA
79 # endif /* SEAICE_ALLOW_EVP */
80 C allow the truncated ellipse rheology (runtime flag SEAICEuseTEM)
81 # undef SEAICE_ALLOW_TEM
82 #else /* not SEAICE_CGRID, but old B-grid */
83 C-- By default for B-grid dynamics solver wind stress under sea-ice is
84 C set to the same value as it would be if there was no sea-ice.
85 C Define following CPP flag for B-grid ice-ocean stress coupling.
86 # define SEAICE_BICE_STRESS
87
88 C-- By default for B-grid dynamics solver surface tilt is obtained
89 C indirectly via geostrophic velocities. Define following CPP
90 C in order to use ETAN instead.
91 # define EXPLICIT_SSH_SLOPE
92 C-- Defining this flag turns on FV-discretization of the B-grid LSOR solver.
93 C It is smoother and includes all metric terms, similar to C-grid solvers.
94 C It is here for completeness, but its usefulness is unclear.
95 # undef SEAICE_LSRBNEW
96 #endif /* SEAICE_CGRID */
97
98 C-- When set limit the Ice-Loading to mass of 1/5 of Surface ocean grid-box
99 #undef SEAICE_CAP_ICELOAD
100 C-- When set use SEAICE_clipVelocties = .true., to clip U/VICE at 40cm/s,
101 C not recommended
102 #define SEAICE_ALLOW_CLIPVELS
103 C-- When set cap the sublimation latent heat flux in solve4temp according
104 C to the available amount of ice+snow. Otherwise this term is treated
105 C like all of the others -- residuals heat and fw stocks are passed to
106 C the ocean at the end of seaice_growth in a conservative manner.
107 C SEAICE_CAP_SUBLIM is not needed as of now, but kept just in case.
108 #undef SEAICE_CAP_SUBLIM
109
110 C-- Enable free drift code
111 #undef SEAICE_ALLOW_FREEDRIFT
112
113 #endif /* ALLOW_SEAICE */
114 #endif /* SEAICE_OPTIONS_H */
