The December 2021 release of our software provides many new features, improvements and fixes!

ecCodes

ecCodes, the heart of GRIB and BUFR handling, brings several features and bug fixes in version 2.24.0.

Note that the high-level Python interface (in eccodes/high_level/*) was always experimental and has been removed in this release.
Please use metview,  cfgrib and/or pdbufr instead.

Also note that ecCodes' Python 2 interface is no longer being developed. Users are strongly advised to migrate to Python 3.

Magics

• The list of predefined geographical areas has been aligned with the list of geographical areas offered in the opencharts catalogue. To use them :

from Magics import macro as magics

area = magics.mmap(subpage_map_area_name=area_name, subpage_map_library_area='on') # where area_name specifies the predefined area to select.
magics.plot(area, magics.mcoast() ) 

• Improve positioning of axis labels in cartesian view

• Improve symbol plotting with NetCDF data
