| Outline of Final Research Achievements |
Carbonaceous particles are one of the biggest uncertainties in climate modeling. Particularly, the generation mechanism of cloud droplets with soot particles as a scaffold is very complicated, so it is strongly desired to develop a novel experimental approach that can characterize individual soot particles levitated in air. In this study, we constructed a new laser trapping and Raman spectroscopy system capable of trapping single carbonaceous particles in air, in which an annular laser beam was employed as a trapping light source.
