Random netcdf4-python notes

Some notes on using netcdf4-python

• Use the shared netcdf4 libraries to compile. (ROMS needs static netcdf4 libraries -- so you need to build both).
  
• The new version returns a np.ma.MaskedArray when there are missing values.
  
• Using ncks (from the netCDF operators) to compress -- need to be careful about specifying netcdf4_classic format. Standard netcdf4 format does not play nice with MFDataset.
  
• The new netCDF4 is DAP enabled, a feature that is passed through to netcdf4-python. All you need to do is specify a DAP-URL, and you can see your data over the internet!
