Correct mapping of variables to IPCC categories #88

Open danielhuppmann opened 2 months ago

danielhuppmann commented 2 months ago

While doing some clean-up of historical emissions timeseries, I was wondering whether the description for the variable "Emissions|CO2|AFOLU" is correct - the current description (copied from NAVIGATE) mentions only IPCC category 3, but if I understand it correctly, this should actually be the sum of IPCC categories 3 and 4.

https://github.com/IAMconsortium/common-definitions/blob/836c3fe6bf24f4ba86de54c6267241fd799714c9/definitions/variable/emissions/emissions.yaml#L14

By extension, "Emissions|CO2|AFOLU|Agriculture" should (closely) match IPCC category 3 and "Emissions|CO2|AFOLU|Land" should match IPCC category 4.

Or am I misinterpreting the variable structure? Please advise @IAMconsortium/common-definitions-emissions
