| Research Abstract |
Understanding the mixing state of atmospheric aerosols, i.e., the differences among individual particles in them, is crucial for assessing the effect of aerosols on climate. In this study, we performed atmospheric aerosol measurements with a focus on particle hygroscopicity as a measure of the aerosol mixing state, thereby acquiring knowledge of the relationship of the particles' hygroscopicity to their composition and cloud condensation nucleus activity. We also assessed the contribution of aerosol particles to cloud formation by making use of the hygroscopicity data. The outcome of this study could serve as a guide for future studies on aerosol mixing states.
