I'm pleased to announce the first beta release of ECMWF `cfgrib`, a Python interface to map GRIB files to the NetCDF Common Data Model following the CF Conventions using ECMWF ecCodes for decoding. Included in the package is a GRIB driver for xarray. https://pypi.org/project/cfgrib/0.9.0 Features with development status **Beta**: - read-only GRIB driver for xarray, - support reading most GRIB 1 and 2 files, - support all modern versions of Python 3.7, 3.6, 3.5 and 2.7, plus PyPy and PyPy3, - support most Linux distributions and MacOS, - only system dependency is the ecCodes C-library (not the Python2-only module), - no install time build (binds with CFFI ABI mode), - read the data lazily and efficiently in terms of both memory usage and disk access. The main repository is hosted on GitHub, testing, bug report and contributions are highly welcomed and appreciated. https://github.com/ecmwf/cfgrib The project is free and open source software distributed under the terms of the Apache License, Version 2.0, the development is led by B-Open <http://bopen.eu> on behalf of ECMWF <https://ecmwf.int>. -- Alessandro Amici <a.amici@bopen.eu> - CTO at B-Open - http://bopen.eu
