The March 2020 release of our software provides many new features, improvements and fixes!

ecCodes, the heart of GRIB and BUFR handling, brings performance improvements, new parameters and several smaller bug fixes/improvements. Please note that ecCodes' Python 2 interface is no longer being developed. Users are strongly advised to migrate to Python 3.

Metview, ECMWF's interactive and batch software for manipulation and plotting of data, brings a number of new features and improvements, such as:

Metview now offers a more streamlined way to view the layer metadata in a plot, plus a large selection of pre-defined areas


Magics, ECMWF's plotting library, adds some smaller improvements:


CodesUI, the standalone combination of Metview's GRIB and BUFR examiners, provides a highly improved initial BUFR message scan (about 50-100 times faster than before), a filter bar for the GRIB namespace list and extra information about BUFR elements.

Please note that when building from source, the minimum CMake version requirement is 3.6.

Metview is built at ECMWF with all the versions of our libraries listed in the table below, and all are included in the March 2020 Metview Bundle. The versions are available on all ECMWF computer systems as "new" versions. If you encounter any issues please feel free to send feedback to Software.Support@ecmwf.int.
