To delete a size 1 domain axis that is spanned by other constructs is hard work. E.g.

n=cf.read(input)
n=n[0]
xkey=n.axis('ncdim%x',key=True)
n.squeeze(xkey,inplace=True)
n.coordinate('latitude').squeeze(n.get_data_axes('latitude').index(xkey),inplace=True)
n.set_data_axes(n.axis('ncdim%y',key=True),n.coordinate('latitude',key=True))
n.del_construct('longitude')
n.del_construct(xkey)

This method is correct, but should be wrapped in a method, e.g. something like

>> n.del_construct('ncdim%x')
ValueError: Can't remove size 1 domain axis that is spanned by other constructs. Consider using Field.del_domain_axis instead.
>>> n = n.del_doman_axis('ncdim%x', remove_size_1=True)
>>>
