Why are some SSP scenarios not available for certain CMIP6 models? Are there specific reasons such as modeling constraints that explain why scenarios such as SSP1-1.9 are missing in some models in MPI-ESM1-2-HR? Are there plans to provide missing simulations in the future?
Dear Francisco,
As you can see in the CMIP6 CDS download form CMIP6 climate projections clicking to the various scenario experiments not all modelling centres run all the scenarios. I don’t think that there are any specific reasons than capacity issues, i.e. not being able to complete all simulations. So there are gaps especially in the less “popular” scenarios. The bad news is that I don’t think that any “missing” simulations will be completed later especially because now the Global Climate Model community is more focusing on to prepare their CMIP7 contribution than of having additional simulations for CMIP6.
I hope it helps, thank you, best regards
