| Research Abstract |
In this study, we obtained the vertical distributions of size distribution and temperature dependence of volatility of aerosols, backscatteringcoefficients of aerosols and cirrus clouds, and humidity, using balloon borne optical particle counter, ground based lidar, and cryogenic frost point hygrometer, respectively, in tropical tropopause layer over Biak, Indonesia. We clarified the mechanism how the high super saturation of the humidity over ice is formed by using microphysical numerical model applying the observed parameters.
