Nobuhiro Moteki gained various observational findings crucial for quantitative simulations of the aerosol-cloud interactions and radiation processes in the global atmosphere, mostly through his originally developed techniques for single-particle analysis. He is one of the world leaders in this ~15 years development of the single-particle laser induced incandescence (single-particle soot photometer) that enabled high-precision fast measurements of black carbon (BC) aerosols. This instrument was used not only for ground-based observations but also for the aircraft campaigns leaded by NASA in U.S.A. and Alfred Wegener Institute in Germany. BC data acquired by his research group have been used worldwide for model validations and contributed to constrain the spatial distribution of BC in global scale. He also developed techniques to quantify the mixing state of BC with other aerosols and BC concentration in water, snow, and ice core, and gained new findings on the wet deposition mechanisms of aerosols and long-term change of anthropogenic BC. In addition, he has developed a technique to measure various kinds of aerosols (e.g., iron oxides, dust) based on the theory of light scattering and absorption, and is conducting an international joint research with NOAA of the United States. In summary, he has leaded international research on climate effects of aerosols, and his cutting-edge achievements are highly regarded worldwide.
