Magics

Magics is the latest generation of the ECMWF’s meteorological plotting software and can be either accessed directly through its Python or Fortran interfaces or by using Metview.

Features:

supports plotting of contours, wind fields, observations, satellite images, symbols, text, axis and graphs (including boxplots)
can plot GRIB 1 and 2 coded data, gaussian grid, regularly spaced grid and fitted data

Limitations:

development stage: Alpha,

Installation

The package is installed from PyPI with:

$ pip install Magics

System dependencies

The python module depends on the ECMWF Magics and eccodes libraries

They can be installed from PyPI with::: $ pip install ecmwflibs

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

$ python -m Magics selfcheck
Found: Magics 'Magics 4.10.0'.
Library: /usr/local/lib/python3.9/site-packages/ecmwflibs/.dylibs/libMagPlus.dylib
Magics home: /usr/local/lib/python3.9/site-packages/ecmwflibs
Your system is ready.

Usage

First, you need a well-formed GRIB file, if you don’t have one at hand you can download our a 2m temperature grib file:

$ wget http://download.ecmwf.int/test-data/magics/2m_temperature.grib

You may try out the high level API in a python interpreter:

from Magics import macro as magics

name = 'magics'
#Setting of the output file name
output = magics.output(output_formats = ['png'],
             output_name_first_page_number = "off",
             output_name = "magics")

#Import the  data
data =  magics.mgrib(grib_input_file_name  = "2m_temperature.grib", )

#Apply an automatic styling
contour = magics.mcont( contour_automatic_setting = "ecmwf", )
coast = magics.mcoast()
magics.plot(output, data, contour, coast)

Running the test program will create a png named magics.png
