About
Rachel Chang is an atmospheric scientist whose research illuminates the critical role of aerosols in the Arctic climate system and global radiative forcing. Her work centers on understanding aerosol sources, distributions, and optical properties—key to reducing uncertainty in climate models. Chang’s most influential contribution, her 2014 study on Arctic aerosol components and absorption (125 citations), used the GEOS-Chem model to construct a three-dimensional representation of Arctic aerosols and ozone, directly addressing why these species are poorly accounted for in models despite their significant warming potential. She has also advanced our understanding of sea spray aerosols, authoring a comprehensive 2013 review (60 citations) on their production mechanisms and optical properties—a vital but historically understudied area of climate science. Most recently, in 2023, Chang developed a novel parameterization for representing organic and secondary inorganic aerosol size distributions, enabling more efficient and accurate global aerosol optical property modeling. Her work bridges detailed microphysics with large-scale climate applications, providing essential tools for both modelers and remote sensing scientists. Chang’s research is foundational for improving predictions of Arctic warming and the global aerosol–climate feedback.
