Did you know Xarray is part of SWE-bench? We are proud of our little contribution to AI research ☺️
May 2
We fine-tuned Alec Radford’s 1930 vintage LLM to solve SWE-bench issues.
After just ‼️250‼️ training examples, the model solves its first issue, a simple patch to the xarray library.

excited to be able to talk to @napari_imaging in the near future!
29 Oct 2025
Today, napari users can’t fully leverage Xarray’s labeled metadata, as slider names, units & dimensions often get out of sync. That’s changing, as napari, Xarray & CellProfiler devs begin a collab to build true metadata-aware visualization across sciences

Check out our new API for seasonal aggreggations, including support for custom seasons!
`ds.resample(time=SeasonResampler(["DJF", "MAM", "JJAS", "ON"]).mean()`
and
`ds.groupby(time=SeasonGrouper(["DJFM", "MAMJ", "JJAS", "SOND"]).mean()`

Calculating quantiles, a common application in
#geospatial workloads, used to be slow due to GIL contention in NumPy.
The new implementation in @dask_dev @xarray_dev is up to a hundred times faster and scales independently of the number of threads 🥳.

At AGU I talked to NASA people about how agencies could better support open-source tools they rely on. I argued that our recent collaboration between Xarray and NASA ESDIS on xarray.DataTree was a good model to copy - read about how it happened here!

Eni Awowale and @lucassterzinger from @NASA_GESDISC presenting on how they use @xarray_dev 's new DataTree functionality for organizing HDF files with many groups!
Wonderful to collaborate directly with @NASA on #opensource for science!
