Python index-calculator is an xclim wrapperto calculate climate indices from CMORized netCDF files.
Project description
index_calculator
Python index_calculator is an xclim wrapper to calculate climate indices from CMORized netCDF files.
Free software: MIT license
Documentation: https://index-calculator.readthedocs.io.
Features
Calculate climate indices via xclim.
Write standardized netCDF attributes.
Write on disk with a project-specific output file name.
Installation
You can install the package directly with pip:
pip install index_calculator
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/index_calculator
cd index_calculator
pip install -e .
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
xarray
xclim
