CliMetLab provides built-in functionalities regarging GRIB format handling.
CliMetLab can read gridded GRIB files and provide data as xarray.Dataset
objects.
CliMetLab has no support for writing grib files.
Warning
The API regarding the GRIB indexing is experimental, things may change.
In addition to reading GRIB from local or remote sources, CliMetLab can also use a precomputed index, avoiding the need to parse the GRIB file to know its content. Using this index allows partial read of local or remote files, and merging of mutliple GRIB sources.
CliMetLab can also create GRIB index files through its command line interface.
Add documentation on grib index.
