Metview Python bindings

Python interface to Metview, a meteorological workstation and batch system for accessing, examining, manipulating and visualising meteorological data. See documentation at

Requirements

• A working Metview 5 installation (at least version 5.0.3, ideally 5.3.0 or above), either from binaries or built from source. Conda packages are available for Linux, and native packages are available for many Linux distributions. See

  • An alternative is to build from the Metview Source Bundle. See

• Ensure that the command 'metview' will run this version by setting your PATH to include the 'bin' directory from where you built or installed it if it's not in a default location.

• A Python 3 interpreter (ideally version >= 3.5)

Install

The package is installed from PyPI with:

$ pip install metview

or from conda-forge with:

$ conda install metview-python -c conda-forge

Test

You may run a simple selfcheck command to ensure that your system is set up correctly:

$ python -m metview selfcheck
Hello world - printed from Metview!
Trying to connect to a Metview installation...
Metview version 5.2.0 found
Your system is ready.

To manually test that your system is properly setup open a Python 3 interpreter and try:

>>> import metview as mv
>>> mv.lowercase('Hello World!')
'hello world!'

Examples
