This study provides an intercomparison of different Stratospheric Aerosol Injection strategies. The strategy choice affects the distribution of aerosol optical depth, the injection efficiency and, crucially, the surface climate response. These results lay the foundation for future trade-off analyses and design strategy optimization.

Short summary
Injecting SO2 into the lower stratosphere can temporarily reduce global mean temperature and mitigate some risks associated with climate change, but injecting it at different latitudes and seasons would have different impacts. This study introduces new stratospheric aerosol injection (SAI) strategies and explores the importance of the choice of SAI strategy, demonstrating that it notably affects the distribution of aerosol cloud, injection efficiency, and various surface climate impacts.
