history

Project history and usage

CDI, the Climate Data Interface, is a C and Fortran library for accessing climate and numerical weather prediction model data in formats such as GRIB, netCDF, SERVICE, EXTRA, and IEG.

Project history

The official MPI-M Redmine overview and wiki describe CDI as a C and Fortran interface to access Climate and NWP model data. The embedded C manual identifies Uwe Schulzweida of the Max Planck Institute for Meteorology as the author and documents CDI C manual version 1.9.9 from October 2020.

The project news on the official overview shows recent release cadence: version 2.0.0 in 2021, 2.1.0 in 2022, 2.2.0 and 2.3.0 in 2023, and 2.4.0 in 2024.

Adoption history

CDI appears as a specialized scientific package rather than a general CLI utility. Its official wiki lists software that uses CDI, including Climate Data Operators, ECHAM, MPIOM, ICON, afterburner, and MATLAB-CDI. Homebrew packaging gives macOS and Linux package-manager users access to the cdi executable and library.

How it is used

CDI is used by climate and meteorology software to read, write, and transform model-data streams across GRIB, netCDF, SERVICE, EXTRA, and IEG formats. The manuals cover C and Fortran bindings, file formats, stream APIs, and compiling/linking with the CDI library.

Why package nerds care

CDI is interesting in package-manager terms because it packages domain infrastructure from climate modeling: a format abstraction layer used by larger tools such as CDO and model workflows, not a standalone consumer application. Its value is in making scientific data formats available through distro and Homebrew dependency graphs.
