[MITgcm-devel] changing offline_exf_seaice

[Jean-Michel Campin]

Hi,

I would like to change the test experiment "offline_exf_seaice",
to use a re-entrant channel with idealized costline (based on the
set-up I put few weeks ago in http://mitgcm.org/~jmc/icedyn_v02.tar.gz)
If things go well, would like to start the changes tomorrow (Friday)
with only the forward set-up for now.

I propose the following forward tests:
(1) input        : seaice-dynamics + thermodynamics and SST relaxation
                   (to replace current offline_exf_seaice/input.seaice)
(2) input.thsice : thermodynamics(pkg/thsice) and SST relaxation
(3) input.thermo : thermodynamics(pkg/seaice) and SST relaxation
(4) input.fixedSST : thermodynamics(pkg/seaice) and fixed SST
                   (to replace current offline_exf_seaice/input.seaicetd)
(5) input.dyn_lsr  : seaice-dynamics, using LSR
(6) input.dyn_jfnk : seaice-dynamics, using JFNK
(7) input.exf_bulk : no seaice, just bulk-formulae
                   (to replace current offline_exf_seaice/input)

I think I have 2 & 5 ready to go. I need to put something for (1)
(otherwise the other will not be tested), and as a temporary test,
I was going to use thsice and LSR (as in 2 + 5) but this could be changed 
later on.

Martin, when you have time, if you can take care of (6), it would be nice.
One thing we could try is to test both pkg/seaice advection and 
pkg/thsice advection in 5 & 6 (e.g., thsice in 5 ?).

Gael, I made several changes to the thermodynamic forcing you sent me,
so that it fits thsice, it's also a stronger forcing (but once I add 
the dynamics, it's still dominated by advection vs thermodynamic forcing),
and I get immediately some places with surface melting and other places
with melting and freezing from below.
When you are back, we could talk about (3) and (4), and from there
it should be easy to get (7) (+ update (1) ?).

Comments and suggestions are welcome (specially for dir name, since
it's a pain to changed them with CVS).

Cheers,
Jean-Michel
