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 Project Grant award for $317,959 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support collaborative research to gain predictive understanding of the physical processes driving rapid wildfire spread and associated smoke transport. The research aims to help guide firefighters to more safely and effectively suppress wildfires by improving adaptation to diverse atmospheric conditions. Key activities include non-modal instability analysis of fire smoke plumes,...
This Project Grant award of $108,519 from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to gain predictive understanding of the physical processes driving rapid wildfire spread and associated smoke transport within the atmospheric boundary layer. The research project, led by the University of Oklahoma, will utilize non-modal instability analysis and large-eddy simulations to investigate the dynamics and thermodynamic processes underlying the rapid growth of billows...
This National Science Foundation project grant of $291,231 supports collaborative research on coastal cloud chemistry during the Eastern Pacific Cloud Aerosol Precipitation Experiment campaign. Funded under the Geosciences program (CFDA 47.050), the award will leverage recent instrumentation developments to augment the Department of Energy's campaign conducted in La Jolla, California from February 2023 to January 2024. Specifically, the University of California, Los Angeles will utilize...
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 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 $150,000 Project Grant under the Geosciences (CFDA 47.050) program to the University of California, Los Angeles (UCLA) - Office of Research Administration. The grant, awarded on October 1, 2023, will support a research project to characterize and understand smoke transport from the 2023 Hawaii wildfires using geostationary satellite observations and numerical modeling. Key objectives include: 1) quantifying the characteristics and temporal...
This three-year project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences provides $195,299 to the University of North Carolina at Chapel Hill for research characterizing the cloud formation properties of secondary organic aerosol formed from aqueous multiphase chemical processes. The research will be conducted from October 2021 through September 2024 under the Geosciences program (CFDA 47.050), which supports basic research into the integrated Earth system...
This National Science Foundation (NSF) Project Grant award, funded under the NSF Geosciences Program (CFDA 47.050), will support a $366,958 research project at the University of Hawaii at Manoa to study the impacts of smoke particles and lofted dust from the 2019-2020 "Black Summer" wildfires in Australia on mixed-phase clouds over the Southern Ocean. The project aims to improve understanding of key aerosol-cloud interaction processes that influence weather, climate, and air quality....
This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to understand the interactions between shallow clouds and Earth's climate system. The award totaling $596,100 was granted to the University of California San Diego's Scripps Institution of Oceanography on February 15, 2025 with a planned completion date of January 31, 2030. The research aims to develop a model that can simulate cloud-scale processes while also capturing...
