Informal Experiments

Lead coordinators: Yen-Ting Hwang, Allison Wing, and Thorsten Mauritsen

Why further CFMIP experiments?

CFMIP has promoted continuously model intercomparison studies which can contribute to answer important scientific questions about roles of clouds and their coupling with circulation in a changing climate. After the CFMIP3 experimental design, connected to CMIP6, was frozen, we received newer ideas of multi-GCM experiments. They are thus not included in the CFMIP3/CMIP6 experiments, but will be supported and encouraged in CFMIP. The CFMIP SSC is now discussing how to help drive these informal CFMIP experiments forward.
