How to do a BSSP126 run with cesm2.1.3 and resolution f09_g17 with the extended SSP126 scenario for years 2100-2300

Dear all,

I did a BSSP126 run with CESM version 2.1.3. and with resolution f09_g17 run for years 2015-2100.

It was setup with command:

./create_newcase --run-unsupported --case b.e21.BSSP126_BPRPcmip6_hosing.f09_g17.001 --compset SSP126_CAM60_CLM50%BGC-CROP-CMIP6DECK_CICE%CMIP6_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BPRP --res f09_g17 --output-root /projects/0/prace_imau/prace_2013081679/cesm2_1_3/

I would now like to extend it to year 2300 under the extended SSP 126 scenario.
How do I do this? I guess I only need different files for ozone, aircrafts etc? e.g.

prescribed_ozone_file = 'ozone_strataero_WACCM_L70_zm5day_2015-2100_SSP126_c190221.nc'
aircraft_specifier = 'ac_CO2 -> emissions-cmip6_CO2_anthro_ac_ssp126_201401-210112_fv_0.9x1.25_c20190207.txt'

Where can I get them?

Do I need to think of certain other things?

Many thanks,
Michael

The SSP extensions weren't available at the time that cesm2.1.3 was made. So I recommend that you use:

release-cesm2.1.4

The main change was to add the extensions and get them working. So I'm pretty sure that it will be compatible
with your previous 2.1.3 simulation. However, I do recommend looking over the ChangeLog in the tag to see what
might have changed and if it matters for what you are doing. I just scanned it and only see a couple mentions of things
that sound answer changing (cesm2.1.4-rc.13, and cesm2.1.4-rc.05 has some CAM changes, and SSP emissions updates
in cesm2.1.4-rc.04). With this branch we made efforts to restrict answer changes unless they were absolutely necessary.


Since, the extensions have datasets for most of the components, the list of datasets you need is quite large, and we
wouldn't be able to list them all off.

Dear Erik,

I am now looking at my old messages and can't believe that I did not respond to your message! I'm very sorry, I thought I did.
Your suggestion was very helpful though, we indeed used release 2.1.4 and were able to extend our run to year 2300 under the extended SSP 126 scenario.

Many thanks!
Michael
