[MITgcm-devel] obcs and passive

[Martin Losch]

Hi,

I am now (after almost a year of procrastinating) ready to check-in 
code that allows open boundary conditions for passive tracers. This 
will affect files of the obcs-pkg and the ptracers-pkg and the file 
pkg/generic_advdiff/gad_advection.F. Not all parts of the code are 
thoroughly tested (in particular, the obcs_external_fields_load part).
There is still no code to deal with Orlanski boundary conditions for 
passive tracers, and honestly, I don't know if I ever get around to 
doing that. I don't know enough about the Orlanski code, and it seems 
to be too tricky for me to do it on the fly.

My question: Should I create a new tag (checkpoint57u_post) after 
checking in my code? I am asking because I no longer see a clear 
pattern in when a tag should be created and I don't want to interfere 
with a policy that I maybe should know (but don't) (o:
