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 $1,882,550 National Science Foundation project grant supports research into the evolution of secondary organic aerosol (SOA) formation processes in urban atmospheres. Funded under the Geosciences program (CFDA 47.050), the three-year award to the University of Colorado will investigate the key gas-phase precursors and sources contributing to SOA, and evolution of associated chemistry over the past decade. A six-week field campaign in the Los Angeles area in summer 2022 aims to compare...
This Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) provides $350,018 to the University of Texas at Dallas (UTD) to conduct research on the coagulation sink rates of sub-10 nm atmospheric particles. The key objectives are to: 1) investigate the effects of van der Waals potentials on coagulation rates, 2) explore the impact of image potentials on coagulation rates, and 3) evaluate how chemical composition influences coagulation sink rates. The...
The National Science Foundation (NSF) Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded a $383,716 Project Grant to The Regents of the University of Colorado to improve understanding and predictive modeling of soot formation in wildfires.
