The research team including Dr. Atsushi Matsuki (Division of Atmospheric Environmental Studies), Mr. Nozomu Tsuchiya (Graduate School of Natural Science and Technology), Dr. Kazuo Kawasaki (University of Toyama), Dr. Takanori Nakano (RIHN) and Dr. Naoki Kaneyasu (AIST) published a paper in Atmospheric Environment.

By newly applying environmental magnetic analysis to atmospheric aerosol in the Asian continental outflow, the team found that the aerosol magnetization is primarily controlled by the magnetite content and found to be remarkably enhanced during Asian dust events rather than pollution episodes. A simple, non-destructive source identification involving aerosol magnetization was proposed as a novel method for monitoring air quality in downwind regions constantly subjected to the influence of mixed dust and air pollution.
