[MITgcm-support] MNC and variable types

[Jean-Michel Campin]

Hi Michael,

I think that the selection of output file precision is 
the same for NetCDF output (MNC) or plain binary output.
So, if you set 
 writeBinaryPrec=64,
in the main parameter file "data", 1rst namelist,
you should get double-precision NetCDF output files.
(in fact, it works for both plain binary
If you are using pkg/diagnostics + MNC,
you can also specify the precision on a per output-file basis,
e.g., in verification/ideal_2D_oce/input/data.diagnostics
  fileName(1) = 'surfDiag',
 fileFlags(1) = 'D       ',
switch this output file to be written in double prec (MNC or plain
binary, depending on what was selected).

Cheers,
Jean-Michel
