Dear Peng,

Thank you for the explanation. I will check it.

Best regards,

Igor,

The normal velocity specified on the OBCS may yield a net inflow and hence growth in SSH.
You may want to try the OBCS balance package, or in a better way, to match the volume on OBCS offline with whatever you used from a coarse resolution product.

Best, Peng

Dear all,

I am trying to model the North Atlantic with MITgcm, but am experiencing unrealistic growth of the sea surface height.
Is there something suspicious in the configuration files (attached) which can provoke such a growth?

Thank you very much in advance!

Best regards,
Igor
