Outline of Final Research Achievements

The interaction of atmospheric aerosol particles with radiation and cloud processes is one of the largest uncertainties in predicting climate change. In this study, I developed a next-generation aerosol model, which can represent number concentration, size distribution, and chemical composition of each particle sufficiently, and validated the aerosol model through comparisons with various aerosol observations in the atmosphere. Then, I evaluated the impact of aerosol particles on climate, such as the heating effect of black carbon (soot) aerosols and its uncertainty and the response of aerosols to changes in emissions from the past to the future, by focusing on related microphysical and chemical processes of aerosols.
