Xarray related projects
-----------------------

Below is a list of existing open source projects that build
functionality upon xarray. See also section :ref:`internals` for more
details on how to build xarray extensions. We also maintain the
`xarray-contrib <https://github.com/xarray-contrib>`_ GitHub organization
as a place to curate projects that build upon xarray.
