grib-api (or ecCodes) - the grib-api library and set of commands for working with and manipulating GRIB files. GRIB is the file format used as input and output for OpenIFS. The grib-api software is available for download from the grib-api software pages. Please use the latest version. Although pre-compiled, binary packages are available, please download the source files and compile it. This is to ensure the same compiler and compiler version is used for the models and grib-api, otherwise errors from mismatching modules are likely. See the grib_api for OpenIFS install page for more details on how to build grib_api for the OpenIFS models.

Offline surface model
netCDF - an implementation of netCDF must be available on the system as the models read/write netcdf format.
