[MITgcm-support] couplimg to EBM

[Hezi Gildor]

hi Patrick,

Yossi and I are aware of the ebm/pkg and indeed it doesn't seem to suit 
what we are looking for (we am looking for a time-dependent model and 
less constrained by present-day observations).  is there any example 
which use the atm_ocn_coupler package?

thanks, hezi.
