- This $213,206 five-year Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will provide new knowledge on the fate of peroxy radicals in the atmosphere. The University of California, Merced will conduct experiments in the NSF NCAR chamber facility to study the mechanisms and kinetics of peroxy radical reactions. The research aims to gain a mechanistic understanding of the interconversion and isomerization of peroxy radical structural isomers at extended...
- This $616,131 National Science Foundation project grant will fund the development of observation-based metrics to evaluate global atmospheric chemistry models at the University of California, Irvine through January 2025. As part of its Geosciences program, which supports basic research in atmospheric, earth, and ocean sciences, the NSF aims to strengthen the scientific enterprise's understanding of the integrated Earth system. Under this award, the university will design, test, and document a...
- This National Science Foundation (NSF) Geosciences program (CFDA 47.050) Project Grant award of $877,929 supports the acquisition of a high-resolution ion mobility time-of-flight mass spectrometer at the University of North Carolina (UNC) Department of Environmental Sciences and Engineering. This cutting-edge instrument will enhance a wide range of ongoing atmospheric chemistry and other research projects at UNC, as well as provide new training and educational opportunities for graduate,...
- The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $675,323 Project Grant to the University of California Irvine (UC Irvine) to study the role of urban and agricultural landscapes in biogenic volatile organic compound (BVOC) emissions and their impact on atmospheric ozone and aerosols. The project combines field and laboratory measurements with numerical modeling to quantify BVOC emissions from managed landscapes and their contribution to air pollution and...
- 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...
- The National Science Foundation (NSF) awarded a $189,884 Project Grant under the Geosciences (CFDA 47.050) program to the Regents of the University of California at Riverside (UC Riverside) for the "Collaborative Research: Coastal Cloud Chemistry during the Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE-CCC)" project. This project will provide an unprecedented characterization of cloud chemical processing to help reduce uncertainties in climate model predictions. The...
This National Science Foundation (NSF) Geosciences program Project Grant award to the University of California, Irvine (UC Irvine) provides $772,000 over a 3-year period from February 2024 to January 2027. The award supports research to study secondary organic particle oxidation mechanisms using novel mass spectrometry techniques, including Matrix Assisted Ionization Mass Spectrometry (MAI-MS) and Easy Ambient Sonic-Spray Ionization Mass Spectrometry (EASI-MS). The objectives are to: 1) elucidate the formation of peroxides and other surface-bound products under different reaction conditions, 2) directly observe organic radicals in viscous model particles, and 3) determine which aromatic oxidation products can be measured using solid organic matrix particles. This work aims to fill a critical knowledge gap in understanding aerosol processes and atmospheric chemistry. The award also includes funding for a postdoctoral researcher, graduate students, and undergraduate students, as well as community education and outreach activities.
