I have encountered a related issue here. When I read a file with netCDF4 compression into a Dataset, a subsequent call to write the dataset using to_netcdf fails.

For instance, using data from the POP model, I can convert output to netCDF4 using NCO $ ncks --netcdf4 --deflate 1 $file nc4-test.nc Then in Python: ds = xr.open_dataset('nc4-test.nc',decode_times=False,decode_coords=False) ds.to_netcdf('test-out.nc') The write fails with: "RuntimeError: NetCDF: Bad chunk sizes."

If I include format = NETCDF3_64BIT, the write completes.

This seems like a bug.
