项目摘要
The project will accurately characterize aerosol particles from aircrafts using a new and improved aerosol-cloud sampler and integrating it with a newly developed fast mobility spectrometer and a scanning cloud condensation nuclei (CCN) instrument during the ICE-T (Ice in Clouds Experiment-Tropical) field campaign. The specific objectives are:1) Accurate sampling of aerosol particles outside and inside clouds considering the possible presence of drizzle, ice, and precipitation using the Clarkson Interstitial Inlet (CII).2) Determine the size distribution of particles smaller than 300 nm in less than 20 seconds using the new fast aerosol mobility spectrometer developed at Clarkson.3) Determine the size-classified CCN fraction of the sampled aerosol using a combination of a fast DMA system and a fast CCN instrument.Intellectual merit:This project addresses the need to improve our understanding of ice nucleation process in the atmosphere. Size distribution measurements of aerosol particles inside and outside of cloud systems will provide critical information about the particle size fractions that are participating in cloud formation. In addition, the mixing nature of the particles will be determined from size-classified CCN measurements. The intellectual merit of this study includes:1) The development and performance validation of a new interstitial aerosol sampler that will provide a critical ability to sample and analyze non-activated aerosol particles in cloud systems.2) Measurements of particle size distributions and size-classified CCN in warm and mixed-phase clouds, resulting in obtaining important data to test existing aerosol-cloud parameterizations and improving our understanding of formation of ice nuclei.Broader Impacts:This work will result in (i) the development of a new aerosol-cloud sampler that can be used for aerosol-cloud system characterization from a wide-range of aircraft platforms, and (ii) validating the performance of a fast sizing particle instrument that will provide near real-time size-resolved measurements of atmospheric aerosol.As a part of this project, two graduate students will be involved. Both graduate students will gain exposure to aircraft-based measurements and in analysis of scientific data. Also, by participating in a field campaign, the students will get an opportunity to interact with established atmospheric scientists, furthering their development as independent researchers.
该项目将在热带云中冰实验实地活动期间,使用一种新的改进的气溶胶云取样器,并将其与新开发的快速迁移率光谱仪和云凝结核扫描仪器相结合,准确地确定飞机上气溶胶颗粒的特征。具体目标是:1)考虑到可能存在的毛毛雨,冰,和降水,使用克拉克森间隙入口(CII)的气溶胶粒子的精确采样云内外。2)确定小于300纳米的粒子的粒度分布,在不到20秒的时间内使用新的快速气溶胶迁移谱仪克拉克森开发。3)确定的大小分类的云凝结核分数的采样气溶胶使用快速DMA系统和快速云凝结核仪器的组合。智力优点:该项目解决了需要提高我们的理解在大气中的冰成核过程。云系内外气溶胶粒子的尺寸分布测量将提供有关参与云形成的粒子尺寸分数的关键信息。 此外,颗粒的混合性质将由粒度分类的CCN测量确定。 这项研究的智力价值包括:1)开发和性能验证了一种新的间隙气溶胶采样器,该采样器将提供对云系统中非活化气溶胶颗粒进行采样和分析的关键能力。2)测量暖云和混合相云中的颗粒尺寸分布和尺寸分类的云凝结核,从而获得重要数据来测试现有的气溶胶云参数化,并提高我们对冰核形成的理解。这项工作将导致(i)开发一种新的气溶胶云采样器,可用于从各种飞机平台表征气溶胶云系统,以及(ii)验证一种快速测量颗粒仪器的性能,该仪器将提供大气气溶胶的近实时尺寸分辨测量。 这两个研究生将获得接触飞机为基础的测量和科学数据的分析。 此外,通过参加实地活动,学生将有机会与知名的大气科学家互动,进一步促进他们作为独立研究人员的发展。
