Airborne Mineral Dust Adds Sulfate To Aerosols
Aerosol particles in the air undergo chemical reactions that change their size and hygroscopicity. Those properties in turn influence how airborne aerosols affect climate by scattering radiation and modifying the brightness and lifetime of clouds. Adding sulfate to those particles is a particularly important process. A research group led by Peter Hoppe, Eliza Harris, and Bärbel Sinha of the Max Planck Institute for Chemistry, in Germany, now pinpoints transition-metal . . .
