2013年2月17日至7月1日，在日本甲府同时进行了使用偏振光学粒子计数器（POPC）和过滤器采样的气溶胶数浓度测量，以开发从POPC测量中识别亚洲尘埃（矿物尘埃）粒子的程序。的相关性的颗粒体积浓度在40个大小的箱的POPC测量，离子物种的质量浓度，和水不溶性颗粒的体积浓度计算的去极化比进行了研究。我们提出了分类标准的矿物粉尘，人为的，海盐粒子使用POPC。使用POPC测量标准估计的矿物尘埃颗粒质量浓度与根据非海盐Ca 2+质量浓度计算的质量浓度密切相关（R2 = 0.936）。
Measurements of aerosol number concentration using a polarization optical particle counter (POPC) and filter sampling were simultaneously conducted in Kofu, Japan, from February 17 till July 1 in 2013 to develop an identification procedure of Asian dust (mineral dust) particles from the POPC measurements. The correlations of the particle volume concentrations in 40-size bins to the depolarization ratio calculated from the POPC measurement, the mass concentrations of ionic species, and the volume concentrations of water-insoluble particles were investigated. We proposed the classification criteria for mineral dust, anthropogenic, and sea-salt particles using the POPC. The mass concentrations of mineral dust particles estimated using the criteria from the POPC measurement correlated strongly with those calculated from the mass concentrations of non-sea-salt Ca 2+(R 2= 0.936).
