Reduced Longwave Absorption of Magnesium Sulfate Aerosol as an Alternative to Sulfuric Acid for Stratospheric Aerosol Injection

Abstract Aqueous sulfuric acid is the benchmark sulfate aerosol for stratospheric aerosol injection (SAI), but /O aerosol absorbs strongly in the infrared, producing longwave warming that significantly offsets its shortwave cooling. Here, we evaluate magnesium sulfate () as a non...
