windspharm
is a Python package for computing quantities derived from global wind
fields using spherical harmonics, licensed under the MIT license.
windspharm provides a user-friendly interface for vector wind computations on the
sphere (e.g., divergence, streamfunction etc.). It is based on the
pyspharm module.
windspharm provides a replacement for the windfield package from CDAT.
windspharm
only requires numpy
and pyspharm
(version 1.0.8 or higher), but for full functionality (meta-data interfaces) one or more of iris
, xarray
or the cdms2
module (from UV-CDAT is required.
The setuptools package is required for installation.
windspharm runs on Python 2 and 3.
Documentation is available online. The package docstrings are also very complete and can be used as a source of reference when working interactively.
If you use windspharm in published research, please cite it by referencing the peer-reviewed paper. You can additionally cite the Zenodo DOI if you need to cite a particular version (but please also cite the paper, it helps me justify my time working on this and similar projects).
The easiest way to install is via conda:
conda install -c conda-forge windspharm
You can also install from the source distribution. Download the archive, unpack it, then enter the source directory and use:
python setup.py install
