Studies on CCN and IN abilities of Dust, Biogenic and Anthropogenic Aerosols

使用SMPS、OPC、CCNC和筑波的Inc.等各种仪器对大气气溶胶进行了全年监测。研究了它们的物理化学性质以及CCN和IN活化谱的季节变化，根据云模拟小室实验、CCNC和Inc.的实验室测量以及详细的云微物理模式模拟，确定了大气气溶胶(如沙尘、生物和人为气溶胶)替代物的CCN和IN能力。发展了一种新的非静力模式微物理参数化方法，将气溶胶作为CCN和IN、云和降水的处理统一起来。

Atmospheric aerosols were monitored year around using various instruments such as SMPS, OPC, CCNC and INC at Tsukuba. Seasonal variations in their physico-chemical properties and CCN and IN activation spectra were investigated.CCN and IN abilities of surrogates for atmospheric aerosols (e.g., dust, biological and anthropogenic aerosols) were formulated based on cloud simulation chamber experiments, laboratory measurements using CCNC and INC and a detailed cloud microphysical model simulations. A novel microphysical parameterization for non-hydrostatic models, which unifies treatments of aerosols acting as CCN and IN, clouds and precipitation, were developed.
