Haywood, Jim M.; Jones, Andy; Bellouin, Nicolas; Stephenson, David (2013): Asymmetric forcing from stratospheric aerosols impacts Sahelian rainfall. In: Nature Climate change. DOI 10.1038/nclimate1857

Aerosol modeling study that is connected to SRM. "We suggest that sporadic volcanic eruptions in the Northern Hemisphere also strongly influence this gradient and cause Sahelian drought. Using de-trended observations from 1900 to 2010, we show that three of the four driest Sahelian summers were preceded by substantial Northern Hemisphere volcanic eruptions."

"Here, we show that using stratospheric passenger flights to inject sulfate aerosols would not cause significant forcing under realistic injection scenarios."
