I am resampling from 3hr data to 1hr data.
```python
resampled_ds = ds.resample('1H', dim='time', keep_attrs=True)

I am using it here:

I ran into the issue there and had to add code to make sure the coordinates were copied.
Thanks!

I'm wary of always keeping coordinates, because some applied operations could make existing coordinates no longer valid. For example, suppose you want to use pandas's faster time-resampling, i.e., `ds.apply(lambda x: x.to_pandas().resample('24H'))`. Any coordinates along the `time` would no longer be valid. We could automatically align the coordinates, but that starts to get increasingly magical...
