[Dart-dev] CESM modelers only - anyone with an opinion, please weigh in

[Nancy Collins]

overall, this looks very good to me.  i'm very happy
trying to keep the scripts with the same name across
cesm components, and have them do similar things.

minor quibbles:

i'd prefer 'perfect_model' as the script name instead of
'perfect_model_obs' because i've heard it called a
'perfect model' experiment more times than a
'perfect model observation' experiment - but maybe
that's a minority opinion.

i'd vote that the cam, pop, and clm scripts that are
for single component assimilations just have the simpler
names (no xxx prepended) and only the fully coupled
version would need the component names prepended.
again - i can be outvoted on this if everyone else feels
differently.

for the cam-only ones - i'm not sure setup_startup is
a helpful name - can't what it needs to do be part of
setup_initial or setup_hybrid?   and perhaps you meant
no_assimiliate.csh in the cam-only section?  you already
have an assimilate.csh script listed as something all
the components would have.

thanks,
n.
