About

Gregory L. Schuster is an atmospheric scientist whose research has fundamentally advanced our understanding of aerosol properties, their classification, and their radiative impacts on Earth's climate system. His most influential work explores the relationship between aerosol optical properties and particle size, most notably his 2006 study on Ångström exponents and bimodal aerosol size distributions, which has become a foundational reference in the field with nearly 940 citations. Schuster has made significant contributions to characterizing black carbon and brown carbon aerosols, developing methods to infer black carbon content from AERONET retrievals and quantifying the direct radiative effects of light-absorbing organic aerosols over regions like the Indo-Gangetic Plain. A recurring theme in his work is improving aerosol measurement infrastructure and retrieval algorithms. He has contributed to the development of AERONET-OC, a critical network for validating ocean color satellite products, and has advanced multiparameter aerosol classification methods applicable to spaceborne polarimetry. His laboratory-based STEAR algorithm evaluation method reflects a rigorous commitment to measurement fidelity. Collectively, Schuster's research — spanning mineral dust characterization, spatial representativeness errors in black carbon networks, and global aerosol climatologies — has shaped how scientists measure, classify, and model atmospheric aerosols across multiple scales.
