Short summary

We document the historical (1750–2023) volcanic sulfur dioxide emission dataset created for phase 7 of the Coupled Model Intercomparison Project, which is a set of coordinated climate model experiments run by modelling center worldwide. Our dataset underpins the stratospheric aerosol optical property dataset which will be used as input by most climate models. However, models with interactive stratospheric aerosol capability can directly input our emission dataset to run CMIP7 experiments.
