[MITgcm-support] parameter set

[Martin Losch]

Hi Xiaohui,

in "data":
to set the monthly interval between forcing field records (months) set
  externForcingPeriod=2592000.,
to have your twelve month forcing repeat year after year set
  periodicExternalForcing=.TRUE.,
  externForcingCycle=31104000.,
These values are then also valid for the obcs-boundary conditions. In  
other words, in "data.obcs" you need to specify the boundary value  
files, just as in exp4 and that's it. This is convenient, but  
inflexible, because it requires that all your forcing and boundary  
values have to be available at the same forcing "frequency/period",  
but you have that.

Alternatively you could use the exf/cal package to be able to set the  
period/cycle indiviually for each external field, but for a simple  
configuration I don't recommend that.
