The main objectives of this project are: (A) the development of a parameterization method to determine particle nucleation rates with uncertainty bounds from vertically resolved field data, including the 2004 New England Air Quality Study (NEAQS); (B) a sampling campaign that ties together extensive ground-based measurements with information from aircraft vertical profiles; and (C) application of the method to new and existing data to predict new particle formation (NPF) in the continental troposphere. The sampling plan will leverage existing ground-based measurements and utilize vertical profiling tools from the National Oceanic and Atmospheric Administration (NOAA), in particular their light aircraft Airborne Aerosol Observatory, AAO. The project includes ten months of ground-based sampling of ultrafine particle concentrations, size distribution, physical properties, sulfur dioxide, and ammonia concentrations and a one-month intensive campaign with the addition of measurements of nitrogen oxides (NOx) and speciated volatile organic compounds (VOCs). These will be supplemented by vertical profiles of a smaller suite of aerosols and gases using the AAO. The measurements will be conducted in Bondville, IL to take advantage of naturally occurring horizontal and vertical concentration gradients, as well as other existing measurements.Broader impacts will be achieved as improved simulation and measurement capabilities for NPF are applied to ongoing efforts to separate the health effects of particles by size (e.g., ultrafine vs. fine) and by source (e.g., in situ nucleation vs. combustion). Collaborations with researchers from both the particle health effect and aerosol-climate fields will allow them to benefit from the results of this project. Additionally, an outreach program for high school science teachers will improve science education in Iowa.

该项目的主要目标是：（a）开发一种参数化方法，以确定粒子成核速率具有不确定性界限，包括垂直解决的场数据，包括2004年新英格兰空气质量研究（NEAQS）； （b）一个抽样活动，将广泛的基于地面的测量与飞机垂直配置文件的信息相关联； （c）将方法应用于新的和现有数据，以预测大陆对流层中的新粒子形成（NPF）。 采样计划将利用现有的基于地面的测量结果，并利用国家海洋和大气管理局（NOAA）的垂直分析工具，尤其是它们的轻型飞机空气气溶胶天文台AAO。 该项目包括超铁颗粒浓度，尺寸分布，物理特性，二氧化硫和氨浓度的十个月采样，以及一个月的强化运动，并增加了对氮氧化物（NOX）（NOX）的测量和指定的挥发性有机化合物（VOC）。 使用AAO，将通过较小的气溶胶和气体组的垂直轮廓来补充这些。 The measurements will be conducted in Bondville, IL to take advantage of naturally occurring horizo​​ntal and vertical concentration gradients, as well as other existing measurements.Broader impacts will be achieved as improved simulation and measurement capabilities for NPF are applied to ongoing efforts to separate the health effects of particles by size (e.g., ultrafine vs. fine) and by source (e.g., in situ nucleation vs. combustion). 与粒子健康效应和气雾气候气候领域的研究人员的合作将使他们从该项目的结果中受益。 此外，高中科学教师的外展计划将改善爱荷华州的科学教育。
