A discovery by former Carnegie Mellon Ph.D. student, Mingyi Wang, leading a large collaborative team, sheds light on one way new particles are forming in the upper troposphere. The study, published in Nature, reveals an unexpected volatile reaction between nitric acid, sulfuric acid, and ammonia, synergistically creating new particles at a rapid rate. The findings suggest that in addition to carbon dioxide, there are other compounds in need of attention and regulation.
