Measurement of the Number-Size Distribution and Hygroscopic Properties of Asian Aerosols for the Aitken, Accumulation and Coarse Modes

该项目将在ACE-Asia（气溶胶表征实验）期间，在NOAA Ron Brown研究船上测量气溶胶的数量、大小分布和吸湿性。将部署的具体仪器包括冷凝颗粒计数器、差分迁移率粒径仪、空气动力学粒径仪和差分迁移率分析仪，提供整个相关粒径范围内的气溶胶粒径分布信息和吸湿性信息，作为粒径的函数，包括粗颗粒。这些测量对于表征ACE-Asia区域气溶胶的物理特性以及对物理、化学和光学特性的封闭研究至关重要。

This project will provide measurements of aerosol number size distribution and hygroscopic properties of aerosols on board the NOAA Ron Brown research vessel during ACE-Asia (Aerosol Characterization Experiment). The specific instruments to be deployed include Condensation Particle Counters, Differential Mobility Particle Sizers, Aerodynamic Particle Sizers, and Differential Mobility Analyzers, providing aerosol size distribution information over the entire relevant size range and hygroscopicity information as a function of particle size, including coarse particles. These measurements are crucial for characterizing the physical properties of the aerosol in the ACE-Asia region, and for closure studies of physical, chemical, and optical properties.
