About
Becky Alexander is a leading atmospheric chemist whose research focuses on the sources, transport, and climate impacts of aerosols and reactive trace gases, particularly in the rapidly changing Arctic. Her work is instrumental in understanding how atmospheric composition drives polar warming. Her most cited paper, "Annual distributions and sources of Arctic aerosol components, aerosol optical depth, and aerosol absorption" (2014, 125 citations), provides a critical 3-D modeling framework using GEOS-Chem to quantify how poorly constrained aerosols and tropospheric ozone contribute to Arctic radiative forcing. This study directly addresses a major gap in climate models, highlighting the importance of long-range pollution transport versus local emissions. Alexander’s contributions have advanced our understanding of aerosol-cloud interactions and the sensitivity of the cryosphere to atmospheric changes. Her research is essential for improving predictions of future Arctic climate, making her a key voice in the field of global change science.
