Ok I see...the basic problem, as @shoyer says, is that `siglay` is used as a dimension coordinate, but it `siglay` itself is two-dimensional: `siglay(siglay, node)`. Xarray can't fit this into...

These are precisely the sort of issues we are trying to solve with [xgcm](https://github.com/xgcm/xgcm). I am about to make a big new release. Using the xgcm concept of an `Axis`...

On today's Xarray dev call, we discussed pursuing another CZI grant to support this feature in Xarray. The image pyramid use case would provide a strong link to the bioimaging...
