Enhanced Python for Graphics and Analysis of Meteorological fields

The epygram library package is a set of Python classes and functions designed to handle meteorological fields in Python, as well as interfacing their storage in various usual (or not) data formats.

EPyGrAM dependencies are available from Pypi (pip install ...), and listed in pyproject.toml. Some packages are mandatory, others are optional, only necessary for the use of specific functionalities or formats. Formats for which the import of the according underlying package fails are deactivated at runtime.

pip install epygram

or

pip3 install epygram

To use specific functionalities which dependencies are not covered by default, you may need to manually pip install the according package(s).

You can also install all optional dependencies using:

pip install epygram[all]

or

more specifically one of the extra group of dependencies:

pip install epygram[<opt>]

with <opt> among (graphics, docs, features, extra_formats), cf. pyproject.toml.

To run tests, cf. tests/README.md.

To generate Sphinx doc: make doc. It will be generated in docs/build/html. Online doc of the latest release on master branch is available at https://umr-cnrm.github.io/EPyGrAM-doc

Some applicative tools in command line are provided and installed by pip.

These tools are available through a single command line epygram with sub-commands:

• epygram -h to list available sub-commands
• epygram <sub-command> -h for auto-documentation of each tool/sub-command.

or as epy_<sub-command> (pip should have placed them in your $PATH).

Example, to plot a field:

• epygram cartoplot <file> -f <field>

or

• epy_cartoplot <file> -f <field>

are equivalent to

• epy_cartoplot.py <file> -f <field> in versions prior to 1.6.0
