The April 2024 release of our software provides many new features, improvements and fixes! Note that the packages below are part of a much larger software stack used at ECMWF, and this is part of a release that is synchronised between all these packages.

ecCodes

ecCodes, the heart of GRIB and BUFR handling, brings several new features, improvements and fixes in version 2.35.0:

• GRIB: Geoiterator for HEALPix nested ordering
• GRIB: Geoiterator for Lambert Conformal in the southern hemisphere
• GRIB2: EERIE (European Eddy RIch Earth System Models) metadata support
• GRIB2: New/updated parameters

Metview

Metview 5.22.0 brings tools to convert your macros to Python! See the documentation here, and also the release notes!

A new entry in the context menu for Macro files offers a conversion to Python; this also works when multiple Macro files are selected

A similar option also exists in the Macro editor

The software versions of this release are available on ECMWF's HPC as part of the module called ecmwf-toolbox (version 2024.04.0.0) and all are included in the The Metview Source Bundle. Versions on conda and brew should be available in the coming days. If you encounter any issues please feel free to use the ECMWF Support Portal.
