👍 This is a persistent problem for me as well.

I often find myself writing a preprocessor function like this python def process_coords(ds, concat_dim='time', drop=True): coord_vars = [v for v in ds.data_vars if concat_dim not in ds[v].dims] if drop: return ds.drop(coord_vars) else: return ds.set_coords(coord_vars) ds = xr.open_mfdataset('*.nc', preprocess=process_coords)

The reason to drop the coordinates is to avoid the comparison that happens when you concatenate coords.
