What I would want is the rolling period to start offsetted e.g. 10 years, with center = False the first 10 years are null. If I set it to False the first 20 years are null. Another option would be to center on the right or something like this? |

Basically, I would like a way to create the same output as this would produce with the flexibility to change the stride (in this case 10 years) xr.concat(
[stack_periods(data), stack_periods(data.isel(time=slice(7200, 360 * 100 - 7200)))],
dim="period",
).sortby("period")is there any way to do that using rolling? |

I would like to split/stack a timeseries into various periods e.g. imagine a 100 year timeseries. That I would like to split into periods of 20 years. I can do this e.g. like this
As you can see, I am creating an artificial time series since the periods dont really have the same timestamps.
Now what I couldnt figure out is, how to generate periods that overlap - e.g. 20 year periods but for every 10 years. I thought
.rolling+.construct< 8000 /code> should somehow do the trick but I am missing an option to center the rolling groups on the left.The data is shifted I think by 10 years that's why there are NaNs in the beginning.
I guess I could somehow shift or add data before doing the rolling, to make that work but maybe there is a more straightforward way to achieve this?
