Compset for SSP2-1.9 simulation

[stevenDH]

Hi

I'm starting some new simulations and I was trying to find out which compset I would use, the idea is to run a simulation under the future climate scenario for an SSP2 world and an RCP1.9 forcing (i.e. 1.5 degrees compatible). I checked the lists of available compsets with CESM here (CESM2 Component Sets Definition) and saw that only a limited set of compset combinations were available, how can I approach this issue? Can I create my own compset for this? I want to do a fully coupled transient emissions driven simulation, is it correct of me to assume that my compset would be something like BSSP219 ?

Thanks a lot for any help with this!
Cheers
Steven

SSP1 1.9 is a low-priority CMIP6 experiment, which CESM has not done. I'm not sure where one can get the forcing data to use.
