cmip table names

[bnlawrence]

We want to make sure we use appropriate table names for our output files. The CMIP list is here, but we probably don't want to comply fully, not least because we have our own output frequencies. We should ensure our file names (and global attributes) include:

• Omon_ (all ocean data will be monthly)
• Ice (to discuss)

Draft for atmosphere (not land):

• Amon_ pt_(all our atmospheric monthly 1m_pt data)
• Amon_ (all our 1m_ average data)
• Aday (all our 1d_ averaged data)
• Aday_pt (all our instantaneous data, 1d_pt)
• A1hr_
• A1hr_pt
• A3hr_
• A3hr_pt_
• A6hr_
• A6hr_pt_

Points of distinction from CMIP, everything starts with A, not just Amon ... and everything is averaged unless it includes pt.

As above, for land, but with L ...

Note that the ESGF records the following options for frequency as opposed to table names:

• 3hr (3573)
• 6hr (1952)
• day (13057)
• fx (2264)
• mon (35607)
• monClim (342)
• subhr (229)
• yr (799)

We can't distinguish L from A short of making a stash item-by-item choice -- but then, what is the criteria to use?

[bnlawrence]

We'd have to distinguish L and A by the CMIP tables if we decide to do it. Every instinct says not to bother, and use the ESGF frequency names, supplemented by _pt as necessary.

Worth noting that there is a discussion about moving away from using table names in CMIP7: A Nomenclature Suitable for Uniquely Defining CMIP Variables. However, for this project it may be better to stay with the CMIP6 naming structure.

Thanks Martin, I hadn't seen that. It might be better to use those as we are almost certainly not going to use the standard CMIP ones ... not least because we will have multiple fields in one file.

[grenville]

We've gone with the ESGF names with an additional pt for instantaneous
