[MITgcm-devel] this weeks share of stupid suggestions about netcdf

[Jean-Michel Campin]

Hi Martin,

I have a comment about point (2):

I whant to keep the possibility of not having missing_value
(as well as having missing_value) for 2 reasons:
a) debugging: I would like to keep the possibility to see in the output 
file the true array that the model has in memory.
b) masking is a funny story, because it does not only depend
on the location of the variable on the C-gridi + vertical location, 
but also the kind of variable: for instance, 
if maskC(i-1)=0; maskC(i)=1, maskW(i)=0
uTrans(i) should be zero (and not missing-value), but at the same 
location, diffusive flux of Temp (=diffKh*d.Theta/dx) should be set 
to missing-value.
To conclude, my impression is that there is a not negligeable
probability that the masking ends up to be wrong, sometimes, for
some variables, depending on what options are used, ...
and in this case, it's good to be able to switch off the "missing_value".
