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.

该项目将在ACE-亚洲（气溶胶特性实验）期间测量NOAA罗恩布朗号研究船上的气溶胶数量、尺寸分布和吸湿性。将部署的具体仪器包括凝聚粒子计数器、微分迁移率粒度分析仪、空气动力学粒度分析仪和微分迁移率分析仪，提供整个相关粒度范围内的气溶胶粒度分布信息和作为粒度（包括粗颗粒）函数的吸湿性信息。这些测量对于确定ACE-亚洲区域气溶胶的物理特性以及物理、化学和光学特性的封闭研究至关重要。
