Radiative forcing for each solution

[nfeldl]

I'm a researcher at UC Santa Cruz interested in the radiative forcing associated with each solution. Do you have any suggestions for the best way to access this data? I see that the radiative forcing is output from the FaIR model. I don't see this output on the solutions.geekhold.com interface.

I think I should be able to fork your repo and edit where the FaIR model is called in solutions/tools/excel_fair_results.py to output radiative forcing (right now it just returns CO2 concentration and temperature), however, a potential issue is that I don't have the xlsm input files:

file2017 = 'CORE-Global_Carbon_Budget_2017 v6.3 (Book V1 Updated Printing).xlsm'
file2020 = 'CORE-Global_GHG_Accounting_2-1-2020_FINAL.xlsm'
process_ghgs(file2020=file2020, file2017=file2017, outdir=args.outdir)

Alternatively, it occurred to me to try to identify the csv files with the emissions reductions timeseries and baseline timeseries and run a standalone instance of the OMS-NetZero/FAIR model.

Any advice you have on the best way to tackle this would be appreciated.

The two CORE-Global*.xlsm files contain results from the original Excel versions of the solution models—which the Project still uses for most things. The Excel models now comprise 100 separate files and have kindof outgrown Excel as a tool, which led to this Python development.

I sent a message to @chadfrisch (Chad Frischmann, VP Research at Project Drawdown) about your inquiry here, and about the Excel files.

I agree that it would be straightforward to modify excel_fair_results.py to output radiative forcing. That script was created to produce results for The Drawdown Review which only needed temperature and concentration.

Regarding the Jupyter interface: there were temperature graphs in the UI at one time but we had to remove them. We need to redo the temperature results to have FaIR compute the overall impact of emissions reductions from all of the Drawdown solutions together, and then compute the fraction of that overall reduction attributable to the one solution being run.

Thank you very much for the information. If you're able to share the CORE-Global*.xlsm files, I would be keen to give this a shot. I'm also happy to share more information about my usage if that's desired.

I appreciate the note about the nonlinearity of the temperature responses and your reimplementation plan. That's good to keep in mind, though for my purposes radiative forcing would be sufficient.

I'd like to start an email thread including you and Chad Frischmann, as me pinging about it on slack isn't working well.

I found an email address for you at https://eps.ucsc.edu/faculty/Profiles/fac-only.php, would it be ok to use that email?

Also: should I address you as Dr, Professor, something else?

[nfeldl]

That email address is the correct one to use. Thank you for doing that.

Either Dr. or Professor works (Nicole is fine too).
