Outline of Final Research Achievements

Field observations of the hygroscopicity and optical properties of atmospheric aerosol were conducted in a forest area of the Kii Peninsula. Hygroscopicity parameters of organic aerosol and biogenic secondary organic aerosol were calculated based on measurements of cloud condensation nuclei. The contributions of organic aerosol and biogenic secondary organic aerosol to the number concentrations of cloud condensation nuclei were assessed. Further, the coatings of black carbon particles were analyzed based on light absorption measurements of the aerosol with and without heating. The hygroscopic growth factors of aerosol particles, the concentrations of tracer species of biogenic secondary organic aerosol, and sky-radiometer data were also obtained. Results and data from this study are expected to be the basis for further characterization of forest aerosols.
