[MITgcm-support] Converting mdsio output to netcdf, or reading mdsio in python

[Ryan Abernathey]

Hi Andrea,

You have 3 options:
- Simply read the mds files into python using np.fromfile (they are  
just raw binary data)
- Use Oliver Jahn's MITgcm python utils package, which contains a  
python mdsio and many other useful scripts (Oliver, is this publicly  
available yet?)
- Upgrade your code to the latest version of layers, which now does  
output via the diagnostics package and therefore should support netcdf  
format. (Disclaimer: I have not tested netcdf output, but maybe Gael  
has?)

Personally, I actually prefer mds output. The main reason is that  
netcdf does not support singleCPUio and consequently produces a  
ridiculous amount of output files that then have to be glued together  
in a separate step.

Best,
Ryan
