Solid aerosols in Arctic atmosphere could impact cloud formation and climate 14 April 2022

Solid aerosols in Arctic atmosphere could impact cloud formation and climate

New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.
