Hi all,

This is a bit of a late announcement, but NCL V4.3.1 and PyNIO V1.2.0
have support built-in for reading and writing netCDF-4 classic files
on systems where netcdf-4.0-beta1 is supported.

With NCL, you can write a netCDF-4 classic file by calling the
"setfileoption" procedure with the "format" option before you call
"addfile" to create a netCDF-4 classic 4 file:

   setfileoption("nc","format","netcdf4classic")
   a = addfile("file.nc","c")

You can further specify a compression level:

   setfileoption("nc","compressionlevel",5)

Similar code exists for PyNIO:

import Nio
opt                  = Nio.options()
opt.Format           = "netcdf4classic"
opt.CompressionLevel = 5

fout = Nio.open_file("file.nc","c",opt)

For more information, see the NCL "setfileoption" or PyNIO documentation:
