Atmospheric Chemistry, Isotope Geochemistry

Outline of research

With the aim of understanding the natural atmospheric environment before the spread of anthropogenic pollution, I am studying how information on the chemical composition of the atmosphere is recorded in ice cores. For example, I am interested in how and to what extent triple-oxygen isotopic composition (Δ17O), the unique signature originated via ozone production, is transferred to which substances through chemical reactions in the atmosphere and snow, and what kind of environmental information is ultimately recorded in ice cores. Understanding these indicators is inextricably linked to understanding atmospheric chemistry. With this interest, I am working on observations of chemical and isotopic indices in the atmosphere and snow, understanding of the factors that cause variations in indices by comparing estimated values by atmospheric chemical transport models with observations, and the development of chemical and isotopic measurement techniques.
