This three-year $570,934 National Science Foundation project grant supports research at the University of California, Irvine to study the effects of phase state on secondary organic aerosol partitioning and its impacts on atmospheric processes at regional and global scales. Specifically, the university will implement methods in the GEOS-Chem model to predict glass transition temperatures and viscosity of secondary organic aerosol. Researchers will derive equilibration timescales of...
The National Science Foundation (NSF) awarded a $797,203 Project Grant under its Geosciences program (CFDA 47.050) to the University of California Irvine (UC Irvine). The goal of this 3-year project, with an end date of January 2027, is to better understand how photochemical reactions in the solid or liquid phase of organic compounds affect the key properties of organic aerosol in the atmosphere. The research will focus on secondary organic aerosol (SOA) and/or biomass burning organic aerosol...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $356,844 to Carnegie Mellon University (CMU) supports research focused on studying the formation and growth of atmospheric particles in the upper troposphere. The project aims to improve understanding of how oxidized organic compounds and inorganic acids interact to drive new-particle formation, as well as the mechanisms governing particle growth from 1-10 nm in size. This research will address key...
