xrft: Fourier transforms for xarray data

|pypi| |conda forge| |conda-forge| |Build Status| |codecov| |docs| |DOI| |license| |Code style|

xrft is an open-source Python package for taking the discrete Fourier transform (DFT) on xarray_ and dask_ arrays.

.. _xarray: http://xarray.pydata.org/en/stable/ .. _dask: https://dask.org

It is:

• Powerful: It keeps the metadata and coordinates of the original xarray dataset and provides a clean work flow of DFT.
• Easy-to-use: It uses the native arguments of numpy FFT_ and provides a simple, high-level API.
• Fast: It uses the dask API of FFT_ and map_blocks_ to allow parallelization of DFT.
