This package offers python tools for the CORDEX community and should make your work with CORDEX grids and meta data easy. Most of the tools leverage the xarray API to create grid and coordinate informations and data of CORDEX domains in the form of an xarray.Dataset directly from the official CORDEX archive specifications.

Please have a look at the introduction noteboook!

Features

• Tools to manage CORDEX grids as xarray datasets.
• Includes coordinate transformations, bounds and vertices for CORDEX datasets.
• Utitlities for cmorization to make the CORDEX ensembles more consistent.

You can use this package, e.g., to easily access CORDEX grid definitions:

import cordex as cx

cx.domain("EUR-11")

to create an xarray Dataset:

and make a quick plot using the accessor:

cx.domain("EUR-11").cx.map()

For planned features, please have a look at the issues, grab one, and contribute!

Installation

You can install py-cordex using pip or conda, e.g.
