pyicon-diagnostics 0.3.6

Diagnostic python software package for ICON

User guide for pyicon

Pyicon is a python post-processing and visualization toolbox for ICON with a focus on ocean data. The three main features of pyicon are:

• a number of functions to facilitate the every-day script-based plotting of ICON data
• an interactive (ncview-like) plotting GUI for Jupyter notebook
• a monitoring suite for ICON ocean simulations which combines dedicated diagnostic plots of an ICON simulation on a website

Pyicon is developed within the DFG-project TRR181 - Energy Transfers in Atmosphere and Ocean.

The pyicon documentation can be found here: documentation

Pyicon is hosted at: (https://gitlab.dkrz.de/m300602/pyicon/)

Installing locally

You can also install pyicon locally via pip. However, due to dependencies of cartopy it is advised to install cartopy first via conda.

conda install xarray cartopy dask -c conda-forge

Once, cartopy is installed in your environment:

pip install git+https://gitlab.dkrz.de/m300602/pyicon.git

Developing

When adding new functions, make sure to document them with a docstring. This should detail what the function does, the arguments and what type of objects it returns. Examples are encouraged. We use so-called "numpy" style docstrings which are then automatically rendered into the sphinx documentation. A guide to numpy style docstrings is available here and they even produce some nice examples.
