Cost analysis of stratospheric albedo modification delivery systems
Environmental Research Letters, 2012 We perform engineering cost analyses of systems capable of delivering 1–5 million metric tonnes (Mt) of albedo modification material to altitudes of 18–30 km. The goal is to compare a range of delivery systems evaluated on a consistent cost basis.
