I also needed something like this but @shoyer decided against this change until there is a cleaner datastore API.

A (very) dirty workaround it to subclass xarray.backends.NetCDF4DataStore and redefine __init__ to accept netcdf datasets as argument:

``` class _NetCDF4DataStore(NetCDF4DataStore): """Just another way to init xarray's datastore.""" def init(self, filename, mode='r', format='NETCDF4', group=None, writer=None, clobber=True, diskless=False, persist=False, ds=None): import netCDF4 as nc4 if format is None: format = 'NETCDF4' if ds is None: ds = nc4.Dataset(filename, mode=mode, clobber=clobber, diskless=diskless, persist=persist, format=format) with close_on_error(ds): self.ds = _nc4_group(ds, group, mode) self.format = format self.is_remote = False self._filename = filename super(NetCDF4DataStore, self).init(writer)

nc = netCDF4.Dataset(filename) ds = xr.open_dataset(_NetCDF4DataStore(filename, ds=nc)) ```
