### What is your issue? **Meta-issue to track all the smaller issues around making xarray and the array API standard compatible with each other.** We've already had - #6804 -...

xarray DataTree

Hi there, I was just wondering if you had seen the prototype [xarray DataTree](https://github.com/TomNicholas/datatree) we're working on? Supporting multi-scale image arrays is supposed to be one of the use cases...

Xarray has objects with both a HTML representation and a printable string repr. The HTML repr is implemented through a `_repr_html_` method, and works great in jupyter normally, where it...

Executing a cell causes the slides to advance, meaning you can't see the output of your cell. This is with the code cell a `fragment` and the next cell a...

Chunking along dimensions of images

The [dask-image library](https://github.com/dask/dask-image) has limited support for dask-powered versions of the `scipy.ndimage` functions that ocetrac wraps. What is a bit confusing though is that some of the functions in dask-image...

Can't call open_mfdataset without creating chunked dask arrays

### What happened? Passing `chunks=None` to `xr.open_dataset`/`open_mfdataset` is supposed to avoid using dask at all, returning lazily-indexed numpy arrays even if dask is installed. However `chunks=None` doesn't currently work for...

New filament statistics analysis module?

Hi, Firstly, what you're doing here is great, this kind of integrated open-source tooling is exactly what the plasma community should be doing! I am planning to write a repo...

open_dict_of_datasets function to open any file containing nested groups

Unclear error message when combine_by_coords doesn't find an index

4

### What is your issue? The error you get from inside `xr.combine_by_coords` when a 1D dimension coordinate is not backed by an index uses outdated verbiage. That's because it predates...

Refactor Dataset internals to store data variables and coordinate variables as separate dicts

There's a _lot_ of other discussion in #9063, but I wanted to pull out this suggestion for independent discussion: >> * Our list of internal attributes on a `DataTree` node...
