[MITgcm-support] linear EOS and Tref

[Jean-Michel Campin]

Hi Martin,

As you mentioned, you should get the same results (not identical
results, because I don't expect to have the same truncation error
in both cases) in the ~.1oC  and ~3.oC initial temp. runs.
So, there is something strange.

Now, to rule out some hypothesis (e.g., advection scheme ???), 
what happens if you change Tref so that you have the same T-Tref 
as in the 1rst run (meaning, setting Tref= 3+1-.1 =3.9 ?) ?
I guess you will reproduce the initial solution, but I think 
it's worth to check.

Cheers,

Jean-Michel
