Lee, Walker Raymond; et al. (2021): High‐latitude stratospheric aerosol geoengineering can be more effective if injection is limited to spring

Lee, Walker Raymond; MacMartin, Douglas G.; Visioni, Daniele; Kravitz, Ben (2021): High‐latitude stratospheric aerosol geoengineering can be more effective if injection is limited to spring. In Geophysical Research Letters. DOI: 10.1029/2021GL092696.

"We demonstrate that spring injection produces approximately twice as much summer AOD as year‐round injection and restores approximately twice as much September sea ice, resulting in less increase in stratospheric sulfur burden, stratospheric heating, and stratospheric ozone depletion per unit of sea ice restored. We also find that differences in AOD between different seasonal injection strategies are small compared to the difference between annual and spring injection."
