A nice addition to the time-series functionality that is built into xray would be the ability to calculate a rolling mean (e.g. for those cases where you've got daily data but you want to work on the 10-day running mean or something).

As far as I'm aware (apologies if I'm wrong), to do a rolling mean at the moment you have to convert to a pandas DataFrame, used the pandas rolling_mean() function and then convert back to an xray data array. This is fine for one dimensional data, but not so nice when you want to do it over a large (time, lat, lon) array.
