When making a CDS request you use a long variable name like ‘2m_temperature’. The resulting netcdf download uses a different much shorter variable name. Like ‘t2m’.
Is this mapping from long to short name documented anywhere? thanks

The list is quite excessive as there are many parameters in the full dataset. This is part of the documentation. See for the parameter listings:

Sweet! Thanks, Laurens_Stoop. I’ve been looking for this full variable name cross-reference for a couple years, and just never found the right place in the documentation etc.
Does anyone know if this “data dictionary” is downloadable in a machine-readable format like an XML, JSON, or Excel file? It would be handy to load this metadata in to our own local database, so it could be used in our client-side code for doing downloads and managing local ERA5 data files. (I see the “Parameter Database” link there, but that seems to be just an interactive “search” web page, not a data set download.) I think I could just scrape this doco web page with BeautifulSoup or the like, but it would be handier to have it in a data-interchange format.
Cheers,
Andrew
