Did you know Xarray is part of SWE-bench? We are proud of our little contribution to AI research ☺️

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. 🧵👇

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 earthmover.io/blog/scientifi…

Scientific Data Visualization with Xarray and Napari | Earthmover

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 🥳. docs.coiled.io/blog/array-qu…

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! xarray.dev/blog/datatree

Xarray x NASA: xarray.DataTree for hierarchical data structures

The new xarray.DataTree class allows working with netCDF/Zarr groups, brought to you in collaboration with NASA!
