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

在筑波使用SMPS、OPC、CCNC和INC等多种仪器对大气气溶胶进行了全年监测。研究了其理化性质、CCN和in活化谱的季节变化。基于云模拟室实验、使用CCNC和INC的实验室测量以及详细的云微物理模型模拟，制定了大气气溶胶（如灰尘、生物和人为气溶胶）替代品的CCN和IN能力。提出了一种新的非流体静力模型的微物理参数化方法，该方法将气溶胶作为CCN和IN、云和降水的处理方法统一起来。

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.
