Biography

Neil Donahue directs the Steinbrenner Institute for Environmental Education and Research. He seeks to understand how Earth’s atmosphere works, and how humans affect the atmosphere. Donahue’s research examines the behavior of organic compounds in Earth’s atmosphere, studying what happens to compounds from both natural sources and human activity when they are emitted into the atmosphere. Recently, his research has focused on the origin and transformations of very small organic particles, which play a critical role in climate change and human health.

Molecular Understanding of the Enhancement in Organic Aerosol Mass at High Relative Humidity

Environmental Science & Technology

2023

The mechanistic pathway by which high relative humidity (RH) affects gas–particle partitioning remains poorly understood, although many studies report increased secondary organic aerosol (SOA) yields at high RH. Here, we use real-time, molecular measurements of both the gas and particle phase to provide a mechanistic understanding of the effect of RH on the partitioning of biogenic oxidized organic molecules (from α-pinene and isoprene) at low temperatures (243 and 263 K) at the CLOUD chamber at CERN.

Sulfur Dioxide Transported From the Residual Layer Drives Atmospheric Nucleation During Haze Periods in Beijing

Geophysical Research Letters

2023

New particle formation (NPF) is a global phenomenon that significantly influences climate. NPF also contributes to haze, with pronounced negative impacts on human health. Theory and observations both show that nucleation is favored during clean days and inhibited during haze episodes due to a high pre-existing condensation sink (CS). Here we show that the surprising occurrence of NPF during haze days in Beijing is associated with a high concentration of sulfuric acid dimers.
