„By injecting different amounts of SO2 at multiple different latitudes, the spatial pattern of aerosol optical depth (AOD) can be partially controlled. This leads to the ability to influence the climate response to geoengineering with stratospheric aerosols, providing the potential for design. We use simulations from the fully-coupled whole-atmosphere chemistry-climate model CESM1(WACCM) to demonstrate that by appropriately combining injection at just four different locations, 30°[nbsp]S, 15°[nbsp]S, 15°[nbsp]N, and 30°[nbsp]N, then three spatial degrees of freedom of AOD can be achieved: an approximately spatially-uniform AOD distribution, the relative difference in AOD between Northern and Southern hemispheres, and the relative AOD in high versus low latitudes.“
