• xarray_extras: Advanced algorithms for xarray
• View page source

This module offers several extensions to xarray, which could not be included into the main module because they fall into one or more of the following categories:

• They’re too experimental
• They’re too niche
• They introduce major new dependencies (e.g.numba or a C compiler)
• They would be better done by doing major rework on multiple packages, and then one would need to wait for said changes to reach a stable release of each package - in the right order.

The API of xarray-extras is unstable by definition, as features will be progressively migrated upwards towards xarray, dask, numpy, pandas, etc.

Features

csv

Multi-threaded CSV writer, much faster thanpandas.DataFrame.to_csv(), with full support fordask anddask distributed.

cumulatives

Advanced cumulative sum/productory/mean functions

interpolate

dask-optimized n-dimensional spline interpolation

numba_extras

Additions to numba

sort

Advanced sort/take functions

stack

Tools for stacking/unstacking dimensions

Credits

• proper_unstack() was originally developed by Legal & General and released to the open source community in 2018.
• All boilerplate is frompython_project_template, which in turn is from xarray.
