Stratospheric aerosol particles and solar-radiation management

"The deliberate injection of particles into the stratosphere has been suggested as a possible geoengineering scheme to mitigate the global warming aspect of climate change."

Lifting options for stratospheric aerosol geoengineering: advantages of tethered balloon systems

"The Royal Society report ‘Geoengineering the Climate’ identified solar radiation management using albedo-enhancing aerosols injected into the stratosphere as the most affordable and effective option for geoengineering, but did not consider in any detail the options for delivery."
