49 stars 12 forks source link

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:

Limitations:

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
