RUI: Excess Sulfate in the Marine Boundary Layer

该奖项支持首席研究员参与被确定为WATOX-CASE（西大西洋协调海气实验）的船/飞机联合抽样考察。美国国家海洋和大气管理局（NOAA）为其正在进行的研究行动提供了船只和飞机的支持。这个国家科学基金会项目的首席研究员将被安排在NOAA的研究船上。整个WATOX-CASE项目将把NOAA科学家的工作与几位大学科学家的努力结合起来，其中包括这笔拨款的首席研究员，他作为NOAA研究船上的客人，将利用这个机会努力实现他自己的特定目标，澄清硫转化机制。具体来说，NSF的研究人员将对气溶胶硫酸盐和其他离子进行尺寸分离测量，并将合作收集和分析船上携带的细颗粒和粗颗粒气溶胶中多达50种化学元素。尺寸光谱测量也将是船上工作的一部分。一些工作将包括对飞机采集的样品进行元素分析。这个NSF项目产生的数据将引起大气化学家的普遍兴趣，他们试图了解海洋边界层中发生的过程，而收集这些数据是该基金的主要目标。

This award supports the participation of the principal investigator in a combined shipboard/aircraft sampling expedition identified as WATOX-CASE (Western Atlantic Ocean Coordinated Air-Sea Experiment). The ship and the aircraft operations are supported by the National Oceanic and Atmospheric Administration (NOAA) for their ongoing research operations. The principal investigator of this NSF project will be accommodated aboard the NOAA research ship. The overall WATOX-CASE project will combine the work of NOAA scientists with the efforts of several university scientists, including the principal investigator for this grant, who, as a guest on the NOAA research ship, will use this opportunity to work toward his own particular goal to clarify sulfur conversion mechanisms. Specifically, the NSF investigator will do size-segretated measurements of aerosol sulfate and other ions, and will collaborate in collecting and analyzing for up to 50 chemical elements in fine- and coarse-fraction aerosols taken on shipboard. Size-spectrum measurements will also be a part of the shipboard work. Some work will be included on the elemental analysis of samples taken by aircraft. The data arising from this NSF project will be of general interest to atmospheric chemists seeking to understand processes occurring in the marine boundary layer, and the collection of these data is the principal objective of the grant.
