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 single-particle mass spectrometry, miniaturized static thermal gradient cloud condensation nuclei instruments, and an instrument for measuring aqueous hydroxyl radicals formed in nascent cloud droplets. This advanced chemical characterization of clouds aims to improve climate model representations of cloud formation by testing hypotheses around the chemical differentiation of activated versus unactivated aerosol particles and the impact of gas-phase compounds and aqueous oxidation on cloud droplet distributions. The project also includes training students in atmospheric research skills. Running from September 1, 2022 to August 31, 2025, this work supports the NSF's mission to expand fundamental earth science knowledge.
