Intake-esm adds the attribute intake_esm_varname to datasets, and I have encountered cases where that ends up being None (still looking for the exact model).

Zarr does not like that type of metadata:

import xarray as xr
ds_test = xr.DataArray(5).to_dataset(name='test')
ds_test.attrs['test'] = None

ds_test.to_zarr('test.zarr')

gives

------------------------

mybinder.org has https://grafana.mybinder.org. It would be good to combine this config with pangeo-data/pangeo#359 once that is finalized.

@jacobtomlinson - if you can help guide me in the right direction, I'm ready to give this a try.
