Appalachian State University received a three-year, $473,741 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to apply measurements, models, and machine learning to improve parameterization of aerosol water uptake and cloud condensation nuclei. The university will collaborate with Georgia Tech researchers to study how particle growth increases with humidity and identify the range of particle sizes that serve as cloud droplet bases. Field campaigns in 2024 will provide data to develop machine learning models, trained and evaluated to calculate aerosol liquid water content and cloud condensation nuclei spectra at Appalachian State's aerosol monitoring site in Boone, North Carolina. The models will then be applied retrospectively to examine changing aerosol hygroscopicity, liquid water content, and spectra over time. The research aims to advance understanding of atmospheric aerosols' crucial impacts on weather and climate through scattering sunlight and acting as cloud droplet bases. The grant also supports the involvement of 8-12 undergraduate and graduate students and collaboration between Appalachian State and a research-intensive institution.
