Major achievements
Dr. Hitoshi Matsui has advanced the understanding of aerosol microphysical properties through the development of an innovative climate-aerosol model, enabling a new evaluation of aerosol impacts on climate. The microphysical properties of aerosols—such as number concentration, particle size distribution, and mixing state—complicate their interactions with the climate system and are a major source of its uncertainty. Dr. Matsui developed the aerosol model ATRAS, which simulates detailed aerosol microphysical processes and properties based on fundamental physical and chemical principles. By implementing this state-of-the-art aerosol model into a climate model, he successfully reproduced aerosol microphysical properties observed through surface, aircraft, and satellite measurements. This work has led to significant advances, including a deeper understanding of aerosol-cloud interactions and a clearer recognition of the climate impacts of black carbon and anthropogenic iron. These achievements have opened new directions for both observational research and model development. In addition, Dr. Matsui has received international recognition for designing and leading several international collaborative studies.
