The September 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 2.38.0:

• Performance improvements
• Latest GRIB/BUFR WMO tables
• New/updated GRIB parameters
• Miscellaneous bug fixes
• See the release notes for full details

Metview

Metview 5.23.0 brings new and improved vertical interpolation functions! pl_to_hl() interpolates data on pressure levels onto height levels, and geometric_height_from_geopotential() and geopotential_from_geometric_height() convert data between geometric height and geopotential height.  See the release notes, which contain details and examples of these and more!

The new functionality allows for height-level cross sections with orography to be produced from pressure-level data.

The software versions of this release are available on ECMWF's HPC as part of the module called ecmwf-toolbox (version 2024.09.0.0) 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.

From Monday 9th September 2024, ecCodes' Python bindings installed from PyPi  additionally provide the ecCodes binary library, and will follow the version numbering of the ecCodes binary library. Thus, the latest version of the Python bindings is now 2.37.0 to match the latest release of the binaries. This improvement should aid installations in environments (such as various Jupyter services) where conda is not available.

ecCodes' Python bindings are installed from PyPi with this command:

pip install eccodes

This installation will, by default, include the ecCodes binary library (as of version 2.37.0), meaning that no external ecCodes binary library is required. If you have an external ecCodes binary library that you wish to use, set the following environment variable before you import eccodes:

export ECCODES_PYTHON_USE_FINDLIBS=1

If this is set, the ecCodes' Python bindings will use the findlibs package to locate the binary library (findlibs was the only mechanism used before version 2.37.0, so this effectively gives the behaviour that existed before version 2.37.0).

In order to gain insights into the search for the binary library, set the following environment variable before importing eccodes:

export ECCODES_PYTHON_TRACE_LIB_SEARCH=1

You may also install a version of ecCodes' Python interface that does not include a binary library at all, in which case the findlibs mechanism will be used as before:

pip install eccodes --no-binary eccodes

This information is also documented in the README file in the eccodes-python repository.

Note that this change does not affect conda installations of ecCodes.
