Abstract. Solar climate intervention using stratospheric aerosol injection is a proposed method of reducing global mean temperatures to reduce some of the consequences of climate change. A detailed assessment of responses and impacts of such an intervention is needed with multiple global models to support societal decisions regarding the use of these approaches to help address climate change. We present here a new modeling protocol and a 10-member ensemble of simulations using one of the most comprehensive Earth system models, aimed at simulating a plausible deployment of stratospheric aerosol injection and reproducibility of simulations using other Earth system models to enable community assessment of responses of the Earth system to solar climate intervention. The Assessing Responses and Impacts of Solar climate intervention on the Earth system with stratospheric aerosol injection (ARISE-SAI) simulations utilize a moderate emission scenario, introduce stratospheric aerosol injection at ~ 21 km in year 2035, and keep global mean surface air temperature near 1.5 °C above the pre-industrial value (ARISE-SAI-1.5). We present here the detailed set-up, aerosol injection strategy, and mean surface climate changes in these simulations so they can be reproduced in other global models.

Short summary
Solar climate intervention using stratospheric aerosol injection is a proposed method of reducing global mean temperatures to reduce some of the consequences of climate change. We present here a new modeling protocol and an ensemble of simulations using one of the most comprehensive Earth system models: the Assessing Responses and Impacts of Solar climate intervention on the Earth system with stratospheric aerosol injection (ARISE-SAI) simulations.
