[MITgcm-support] input variables not recognised

[Martin Losch]

Elja,

put
forcing_In_AB = .false.,
into PARM03 in data, that should do it. This flag makes to model do a  
separate (Eulerian?) time step for the tendencies due to surface  
forcing. This is sometime favorable for stability reasons (and some  
package such as seaice work only with this).

Alternatively, if you really want to keep the momentum forcing within  
the Adams-Bashforth time stepping, then you could set  
tracForcingOutAB = 1, explicitly, but I don't see, why you would want  
to do this.
