About
Christina Hsu is a leading figure in satellite remote sensing of aerosols, whose work has fundamentally advanced our understanding of how airborne particles influence climate. Her research centers on the development and intercomparison of satellite-derived aerosol optical depth (AOD) datasets, a critical constraint for climate models. In her landmark 2020 AeroCom–AeroSat study, cited over 80 times, she led a comprehensive evaluation of 14 satellite products from five different sensors, systematically characterizing uncertainties across nine retrieval algorithm families. This work has become a foundational reference for model evaluation. Hsu has also made pivotal contributions to understanding the radiative impact of absorbing aerosols, particularly biomass burning smoke. Her 2019 study on smoke transport and optical properties over the southeast Atlantic, using the ALADIN regional climate model, directly addressed the complex interactions between aerosols and stratocumulus clouds. Earlier, her 2009 work during the Dust and Biomass-burning Experiment (DABEX) provided critical aircraft, satellite, and ground-based measurements that validated remote sensing retrievals over West Africa. Through these studies, Hsu has established herself as a key architect of the observational framework used to assess aerosol radiative forcing.
