xrft: Fourier transforms for xarray data¶
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.
xrft is at early stage of development and will keep improving in the future. The discrete Fourier transform API should be quite stable, but minor utilities could change in the next version. If you find any bugs or would like to request any enhancements, please raise an issue on GitHub.
