xweights 0.2.6

Python xweights contains functionsto create grid weighted area means

xweights

Python “xweights” contains functions to calculate grid weighted area means from predefined regions or from an user-given shapefile. This tool is a wrapper around the python package xesmf https://xesmf.readthedocs.io

• Free software: MIT license

• Documentation: https://xweights.readthedocs.io

Features

• Calculate grid-weighted-means and save the output as CSV file

• As input you can choose between files on disk and intake-esm catalogues. Xarray dataset input is under development.

• Use all these features as an command-line tool too

Installation

Note: Before building xweights from source, you nedd first install cartopy by using conda:

conda install -c conda-forge cartopy

You can install the package directly with pip:

pip install xweights

If you want to contribute, I recommend cloning the repository and installing the package in development mode, e.g.

git clone https://github.com/ludwiglierhammer/xweights.git
cd xweights
pip install -e .

In additon you have to install xESMF using _Conda:

conda install -c conda-forge xesmf

This will install the package but you can still edit it and you don’t need the package in your PYTHONPATH

Requirements

• python3.6 or higher

• numpy

• pandas

• geopandas

• intake-esm

• xarray

• py-cordex

• xesmf
