iris-grib
The library iris-grib provides functionality for converting between weather and climate datasets that are stored as GRIB files and Iris cubes. GRIB files can be loaded as Iris cubes using iris-grib so that you can use Iris for analysing and visualising the contents of the GRIB files. Iris cubes can be saved to GRIB files using iris-grib.
The contents of iris-grib represent the former grib loading and saving capabilities of Iris itself. These capabilities have been separated into a discrete library so that Iris becomes less monolithic as a library.
