Visioni, Daniele; Pitari, Giovanni; Tuccella, Paolo; Curci, Gabriele (2018): Sulfur deposition changes under sulfate geoengineering conditions. Quasi-biennial oscillation effects on the transport and lifetime of stratospheric aerosols. In Atmos. Chem. Phys 18 (4), pp.[nbsp]2787–2808. DOI: 10.5194/acp-18-2787-2018.
„Among several possible environmental side effects, the increase in sulfur deposition deserves additional investigation. In this study we present results from a composition–climate coupled model (University of L’Aquila Composition-Chemistry Model, ULAQ-CCM) and a chemistry-transport model (Goddard Earth Observing System Chemistry-Transport Model, GEOS-Chem), assuming a sustained lower-stratospheric equatorial injection of 8 Tg SO2 yr−1. Total S deposition is found to globally increase by 5.2 % when sulfate geoengineering is deployed, with a clear interhemispheric asymmetry (+3.8 and +10.3 % in the Northern Hemisphere (NH) and the Southern Hemisphere (SH), due to +2.2 and +1.8 Tg S yr−1, respectively).„
