[MITgcm-support] MIT OGCM - Anamoly run

[anuradha.modi at iccsir.org]

Dear Users,

I spun up the MIT OGCM model with climatological data for 500 years
Now I am going to start the experiments.

I need to force the model with monthly EmP anomalies (which I computed using observations),
To use this input EmP data file in the model, 
Whether I need to change the format of this EmP anomaly file?
Whether model requires a particular input file format ?
If so, to change the input into model required format, what software I should use?

Right now, during this climatological run, I plotted the climatological forcing fields using Grads software.
It have only one record with these specifications...
The grads ctl file as follows
dset ^eSatSea22.dat
title model temperature
undef -999.
options little_endian

So, now for EmP anomaly run, the input should be in the above ctl file mentioned format?

Any help is highly appreciable..
