| Research Abstract |
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.
