Hi @cloneof sorry for the delay! Looking at these questions and the post you mentioned above I think you would need to either (1) update the input files to the Socioeconomic component to match the ones you are hoping to use or (2) use the scenconverter.jl component and link it up if you don’t have all of the variables that the Socioeconomic component wants.
I see some scenario data here but I don’t think the current FUND model in Mimi has a simple switch or Parameter to use different SRES scenarios. If you have the driving scenario data that you would want to use, I can help you step through how you would update the parameters to try running it though. The advice may look a lot like the post mentioned already … but we can see if anything in Mimi has updated since then since it was a few years ago.
