CR-CMIP-0-4-0: greenhouse gas concentrations - feedback, observations and issues

[znichollscr]

Known issues:

• still no EESC (equivalent effective stratospheric chlorine), but probably could be

From @vnaik60: Add the normal names for species into the variable attributes e.g. hcc140a should have a long_name of "CH3CCl3".

Me: Yep, I'll use the mapping we already have as the basis: https://input4mips-controlled-vocabularies-cvs.readthedocs.io/en/stable/dataset-overviews/greenhouse-gas-concentrations/#variable-name-mapping

Thank you!

@vnaik60 I'm thinking of using the more normal names for the variable names, and just leaving the standard names using these weird names. What do you think?

The affected variables would be:

• new name : current name
• "c2f6": "pfc116"
• "c3f8": "pfc218"
• "c4f10": "pfc3110"
• "c5f12": "pfc4112"
• "c6f14": "pfc5114"
• "c7f16": "pfc6116"
• "c8f18": "pfc7118"
• "cc4f8": "pfc318"
• "ch3ccl3": "hcc140a"

That would mean we would end up with the below instead

netcdf ch3ccl3_input4MIPs_GHGConcentrations_CMIP_CR-CMIP-testing_gnz_175001-202212 {
dimensions:
	time = UNLIMITED ; // (3276 currently)
	lat = 12 ;
	bnds = 2 ;
variables:
	float ch3ccl3(time, lat) ;
		ch3ccl3:standard_name = "mole_fraction_of_hcc140a_in_air" ;
		ch3ccl3:long_name = "ch3ccl3" ;
		ch3ccl3:units = "ppt" ;
		ch3ccl3:cell_methods = "area: time: mean" ;
...

Yes, this sounds good! Thanks.
