Trying again

Hi @aidanheerdegen - I am belatedly getting back to this data publishing pipeline.
First attempt revealed some errors like this:

Deleting following variables with a time dimension from ocean_grid.nc: ['time', 'drag_coeff']
Traceback (most recent call last):

I am testing out whether this is due to the 19.07 update and will report back.

[AndyHoggANU]

Just to confirm - this is fixed by reverting back to 19.04, but it would be good if the unstable branch could be updated so that it works there too.

[aidanheerdegen]

This is a bug in xarray

pydata/xarray#3215

Work-around is to set this environment variable:

NUMPY_EXPERIMENTAL_ARRAY_FUNCTION=0

I have submitted a PR with a code fix pydata/xarray#3220
