The National Science Foundation Office of Integrative Activities awarded the Desert Research Institute $299,567 on February 1, 2027, under the Integrative Activities program (CFDA 47.083) to support research on low cloud evolution and aerosol interactions. The award funds a fellowship for an assistant research professor and training for a graduate student at Desert Research Institute, with collaboration from Dr. Sarah Doherty at the University of Washington. The research investigates how marine low clouds evolve as they move across the subtropical eastern Pacific Ocean and how atmospheric aerosols affect their development and ability to reflect incoming sunlight. The project integrates satellite observations, Lagrangian trajectory analysis, machine learning, and large-eddy simulation modeling to identify environmental conditions and physical mechanisms controlling cloud evolution pathways. Deliverables include a comprehensive library of Lagrangian trajectories characterizing cloud evolution across aerosol and meteorological conditions, multiple machine learning models employing explainable artificial intelligence techniques to identify controlling atmospheric variables, and simulations of selected trajectories using large-eddy simulation. Work is performed in Seattle, Washington, with a period of performance from February 1, 2027, through January 31, 2029. The project aims to improve understanding of uncertainty in earth system prediction, strengthen institutional collaboration, train atmospheric scientists, and produce datasets and computational tools for the broader scientific community.
