Lauren Zamora, UMD: To Arctic Clouds From Saharan Dust

COMPASS 2026-01-14: Lauren Zamora, U Maryland & NASA Goddard Space Flight Center "To Arctic Clouds From Saharan Dust: An Alumnus Career Retrospective" Aerosol–cloud interactions are one of the largest sources of uncertainty in climate projections for the rapidly warming Arctic, particularly through their influence on the radiative properties of mixed‑phase clouds containing both liquid water and ice. In this talk, I will present a retrospective of my research on aerosol impacts on the environment, tracing a trajectory from PhD work at Rosenstiel on Saharan dust and atmospheric nutrient deposition to the ocean to my current focus on Arctic aerosol–cloud interactions. I will talk about how my training in marine and atmospheric chemistry with Dennis Hansell and Joe Prospero continues to inform my research approach. The presentation will focus primarily on recent developments in understanding Arctic aerosol-cloud interactions, including new satellite observational methods, community scientific priorities identified at a recent QuIESCENT international workshop, and new observations from NASA's 2024 ARCSIX (Arctic Radiation-Cloud-Aerosol-Surface Interaction Experiment) field campaign. I will also discuss emerging satellite remote sensing approaches and recent work on polar mixed‑phase cloud thinning as a potential climate intervention strategy. I will conclude by briefly reflecting on career lessons learned that may be helpful for current graduate students, including managing research transitions, building diverse mentoring networks, and approaching complex scientific problems strategically.
