Polarization Optical Particle Counter data on the AGB Shirase in JARE65

The data are measured by a polarization optical particle counter, which measures the intensity of light scattering by atmospheric aerosol particles and the depolarization ratio to determine the particle size, shape and concentration. The data are classified into mineral particles, deliquescent fine particles, and deliquescent coarse particles based on the particle size and the depolarization ratio, and the number and mass concentrations are derived.本数据集由偏振光学粒子计数器（polarization optical particle counter）测得，该仪器通过采集大气气溶胶粒子的光散射强度与退偏振比（depolarization ratio），实现对粒子粒径、形态及浓度的测定。该数据集依据粒子粒径与退偏振比被划分为矿物颗粒、吸湿性细颗粒及吸湿性粗颗粒，并已推导得到粒子的数浓度与质量浓度。
