Install: brew install eccodes

About:
Eccodes is a command-line tool and API for decoding and encoding meteorological data formats. It provides high-performance processing of GRIB (General Regularly-distributed Information in Binary form) and BUFR (Binary Universal Form for the Representation of meteorological data) files. This software is essential for weather forecasting, climate research, and atmospheric analysis workflows.

Key Features:

Supports GRIB 1/2 and BUFR 3/4 decoding/encoding
High-performance C library with Python and Fortran interfaces
Command-line utilities for data inspection and conversion
ECMWF-supported and open-source implementation

Use Cases:

Processing weather forecast model outputs for meteorological analysis
Converting satellite and observational data into standard formats
Building automated weather data ingestion pipelines

Alternatives:

wgrib2 – wgrib2 is specialized for GRIB2 only, while eccodes handles both GRIB and BUFR formats with a unified API
netcdf – NetCDF is a general scientific data format, whereas eccodes specifically targets meteorological data standards
