Grib encoding errors

Some original files from Meteo-France have strange or erroneous metadata. They may not open with all tools, they may require custom grib tables and they may report strange or erroneous variables names. As a result, the associated .inv files are also contaminated by those errors.

Package files

Multiple parameters are merged in a same grib file. Each package has a special name:

HPx for altitude data
IPx for isobaric data
SPx for surface or single level data

The packages are not the same across different models. The SP1 package for arome-france does not contains the same data than the SP1 package from arpege-france.

We do not provide the documentation for the content of v1 packages, as this dataset is only provided for compatibility with already existing systems.

You can have a look to the .inv inventory files, but remember about the errors explained above.

We provide inventory files if you need to download only certain parts of the GRIBs.

To get the inventory files, replace .grib2 extension with .inv in the url.
