initial |
NRREC: Switch to indicate start or re-start from a previous solution. nrrec is the
time index of the initial or re-start NetCDF file assigned for initialization.
If nrrec is negative (say nrrec = -1), the model will start from the most recent time
record. That is, the initialization record is assigned internally.
filename: Name of file containing the initial state.

sponge |
sponge parameters are only needed if SPONGE_GRID is undefined in set_global_definitions.h;
otherwise, these parameters are assigned internally.
X_SPONGE [m]: width of sponge layers
V_SPONGE [m2/s]: viscosity/diffusivity values in sponge layers. These values follow a
cosine profile from zero interior value to V_SPONGE at the boundary.
|
nudg_cof |
TauT_in [days]: Short nudging time scale used in radiative open boundary conditions for
tracer signal propagating inward the computational domain. This coefficient is used at
boundary points and imposes strong nudging towards external data
TauT_out [days]: Long nudging time scale used in radiative open boundary conditions for
tracer signal propagating outward the computational domain. This coefficient is used at
boundary points and imposes mild nudging towards external data. If CLIMATOLOGY is defined,
it is also used in nudging layers with gradual decrease (cosine profile) from the open
boundary to the inner border of the nudging layer.
TauM_in [days]: Same as above, but for momentum equations
TauM_out [days]: Same as above, but for momentum equations
