xarrayMannKendall is a module to compute linear trends over 2D and 3D arrays.
For 2D arrays xarrayMannKendall uses xarray parallel capabilities to speed up the computation.
For more information on the Mann-Kendall method please refer to:

A useful resource can be found here. Finally, another library that allows to compute a larger range of Mann-Kendall methods is pyMannKendall.
This package was primarily developed for the analyisis of ocean Kinetic Energy trends over the satellite record period that can be found at doi:10.1038/s41558-021-01006-9.
The data analysed with using this module can be found at EKE_SST_trends repository.
You can install the latest tagged release of this package via conda-forge by:
conda install -c conda-forge xarrayMannKendall
Alternatively, you can clone the repository and install. To do so, make sure you
have the module requirements (numpy & xarray):
pip install -r requirements.txt
conda install --file ./requirements.txt
Now you can install the module
pip install -e .
for local installation use
pip install --ignore-installed --user .
