Laakso, Anton; Korhonen, Hannele; Romakkaniemi, Sami; Kokkola, Harri (2017): Radiative and climate effects of stratospheric sulfur geoengineering using seasonally varying injection areas. In: Atmos. Chem. Phys. Discuss., S. 1–25. DOI: 10.5194/acp-2017-107.

"In this study we employ alternative aerosol injection scenarios to investigate if the resulting radiative forcing can be optimized to be zonally more uniform without decreasing the global efficacy. We used a global aerosol-climate model together with an Earth system model to study the radiative and climate effects of stratospheric sulfur injection scenarios with different injection areas. According to our simulations, varying the SO2 injection area seasonally would result in a similar global mean cooling effect as injecting SO2 to the equator, but with a more uniform zonal distribution of shortwave radiative forcing."
