Indeed, typical long names don't follow the snake_case convention, but are rather more free-form and human readable/understandable. They are chosen by the user, often giving information beyond the standard names. Examples from CMIP6 (Omon table, variables tos and tosga): tos: - standard name: sea_surface_temperature - long name: Sea Surface Temperature tosga: - standard name: sea_surface_temperature - long name: Global Average Sea Surface Temperature Cheers Klaus On 13/03/2019 10:11, Dan Say wrote: > Good morning, > > > I am happy to go with the IUPAC names if needs be however, hfc is > standard nomenclature and I would have thought the most likely term to > be searched.
