add TRACI gwp's with biogenic variations

[DEQmbrown2]

in his short list of impact categories to publish in the 1.0 version of WIC, Peter C marked TRACI-based GWP's as desirable outputs for some WIC users (even though DEQ itself is using IPCC GWP's). See highlighted squares below, which Peter marked "TRUE" but I changed to blank.

i have temporarily removed the TRACI based values from the shortlist because I see that TRACI has both biogenic and non-biogenic options. I need to examine my own code to make sure those things will get imported correctly.

@DEQpcanepa, do our Slash-based and EpaFcs-based modifications still apply when using the TRACI framework?

Thanks, Martin

Hi Martin - the Slash and EPA FCS correction factors do apply when using the TRACI methodology, itself based on the IPCC methodology. Of course they only apply when selecting the version that "includes biogenic carbon," and that's the same whether using IPCC or TRACI.

I did a short check (see attached) to compare the differences between IPCC and TRACI. IPCC's latest impact category indicator contains many more types of greenhouse gas emissions than TRACI (263 in IPCC vs. 144 in TRACI 2.1). Of the 144 emissions classified by TRACI 142 of them are also in IPCC. So all of this suggests that IPCC perhaps is more comprehensive than TRACI, so it might be best to favor IPCC over TRACI.

Ok, thanks for the clarification. I'm not sure how much work this is, so I may put it off into the first bugfix release.

Result: I did put this issue into the project for the first revised release because TRACI isn't specifically promised in our existing documentation. @DEQpcanepa , you don't need to work on this at all, but if you want to add issues to that project, you can see the project board at https://github.com/OR-Dept-Environmental-Quality/wic-base/projects/3 .
