My apologies for having to re-open the issue, I should have tried the fix before closing.

I get the following error after changing my last line to: ds.to_netcdf('/tmp/test.nc', encoding={'lat': {'_FillValue': None}, 'lon': {'_FillValue': None}}) as suggested.

File "/path/to/python3.6/site-packages/xarray/backends/netCDF4_.py", line 354, in prepare_variable unlimited_dims=unlimited_dims) File "/path/to/python3.6/site-packages/xarray/backends/netCDF4_.py", line 176, in _extract_nc4_variable_encoding ' %r' % (backend, invalid)) ValueError: unexpected encoding parameters for 'netCDF4' backend: ['_FillValue'] Do we just need to append '_FillValue' to the list of ` valid_encodings = set(['zlib', 'complevel', 'fletcher32', 'contiguous', 'chunksizes', 'shuffle'])
