New Particle Formation in the Upper Troposphere and Lower Stratosphere During HIAPER Progressive Science Missions

该奖项支持肯特州立大学的一名新教员与丹佛大学经验丰富的团队一起参与HIAPER进步科学（HPS）项目。HPS旨在展示HIAPER（高空环境研究平台）飞机执行科学任务的能力，通过飞行有限的有效载荷，保证至少适度的科学回报。本项目提供资金，利用美国丹佛原子核模式气溶胶粒径谱仪（NMASS）和聚焦腔气溶胶谱仪（FCAS），利用HIAPER测量4-2000nm范围内的气溶胶粒径分布。这项工作的目的是研究自由对流层中新粒子的形成。这些测量将提供有关新粒子形成的纬度和高度依赖性的数据，并检查控制粒子形成过程的关键因素，如阳光照射和预先存在的气溶胶的表面积。

This award supports the participation of a new faculty member at Kent State University together with an experienced team at the University of Denver in the HIAPER Progressive Science (HPS) program. HPS is intended to demonstrate the abilities of the HIAPER (HIgh Altitude Platform for Environmental Research) aircraft to perform science missions by flying limited payloads that promise at least modest scientific return. This project provides funds to make measurements of aerosol size distributions over the range of 4-2000nm with HIAPER, using the U. Denver Nuclei Mode Aerosol Size Spectrometer (NMASS) and the Focused Cavity Aerosol Spectrometer (FCAS). The objectives of this work are to study new particle formation in the free troposphere. The measurements will provide data on the latitude and altitude dependence of new particle formation and examine key factors that govern particle formation processes, such as sun exposure and surface area of pre-existing aerosol.
