SSP in cesm2.2.0

[ybj]

Hello everyone, I am currently simulating sea ice for the years 1980-2020 using CESM version 2.2.0. Initially, I conducted a BHIST simulation covering the period from 1980 to 2014. Now that I have the restart files for January 1, 2015, I want to continue my simulation with the SSP585 scenario. Here are the steps I have taken:
/work/software/cesm/2.2.0_openmpi2020/cime/scripts/create_newcase --case ~/ymt/case_cesm2/control_b.e22.BSSP585.f09_g17.CMIP6-historical.001 --compset SSP585_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD --res f09_g17 --run-unsupported
Subsequently, on my first attempt, I modified the pelayout and xml files, but encountered errors during the build process. On my second attempt, I tried not to make any changes and went straight to setup and build, but the same errors occurred as in the first attempt.Attached below is the log.

My question is: Is CESM 2.2.0 not compatible with SSP585? I didn't see SSP585 in the compset, but isn't the compset customizable according to one's requirements? Therefore, I modified the long_name based on BHIST to SSP585_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD. Or is it possible that the long_name I set is incorrect?

In your cesm directory,
cd cime/scripts
./query_config --compsets
to see short and long names that may help you verify if your compset name looks right.

You may also find it useful to compare the case directories of the two cases, the one that fails and the one that works. If nothing stands out, then maybe you do want to try a different ssp in case that is the problem.

Thank you for your suggestion.
I tried the command you mentioned: query_config --compsets. I only found the existence of ISSP585Clm50BgcCrop, but not BSSP585. This is because I saw only a slight difference in the long_name between BHIST and BSSP585 in the CESM 2.1.3 version. In CESM 2.1.3, the long_name for BHIST is: HIST_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD, and for BSSP585 it is: SSP585_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD. Could it be that this is not applicable to CESM 2.2.0? There are also differences in the BHIST between CESM 2.2.0 and CESM 2.1.3. In CESM 2.2.0, the BHIST is: HIST_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD.

Perhaps I need to try a different approach. I have a few more questions: 1. Since I just want to simulate the period from 1980 to 2020, I would like to know what kind of forcings will be used if I only use the entire BHIST period for the simulation from 2015 to 2020. 2. Are there already forcings available from 1850 to 2020 that can be directly used for model simulation. 3. Why can't I find the compset for CESM 2.1.5 on the compset introduction website.
Thanks.

In case this helps, please keep in mind that HIST ends in 2015 and SSP starts in 2015 in our compset definitions.
