This field campaign includes test flights to certify instrumentation not previously flown on the NSF/NCAR Gulfstream V research aircraft. It also includes flights to address several scientific hypotheses, including the investigation of ozone loss in the upper troposphere and lower stratosphere (UTLS) due to iodine in the region. The research results from this novel collection of instrumentation flown in the UTLS is expected to significantly improve the scientific understanding of chemistry in the region.This project will test advanced instrumentation and a newly designed laminar flow inlet suitable for measuring condensable vapors and ambient ions on the GV research aircraft to achieve the following objectives: (1) The aircraft payload has been developed to experimentally constrain 90% of total iodine in the stratosphere by attempting the first simultaneous aircraft measurements of gas- and particle iodine; (2) Iodic acid (HIO3), a widespread condensable vapor that grows nanoparticles and drives changes in gas-particle partitioning of iodine, will be measured for the first time in the UTLS by aircraft; (3) Simultaneous measurements of ambient ions (number & chemical composition) will identify those condensable vapors that participate in ion-induced nucleation in the UTLS. Initial test flights will be conducted in Colorado, after which a limited number of (~3-6) exploratory science flights are planned from Kona Hawaii to demonstrate the science readiness of the aircraft payload, evaluate instrument performance, and to inform long-term measurements at Mauna Loa Observatory (MLO) in preparation for future campaigns. Aircraft measurements made above MLO, along with iodine oxide (IO) radical measurements from a MAX-DOAS instrument at MLO, will enable the characterization of the nature and shape of the vertical profile of IO above MLO. This project includes collaboration with scientists from three U.S. National Laboratories, one foreign university, and 5 foreign National Laboratories. Four graduate students and three postdocs will interact with scientists at eleven different institutions in the U.S., Germany, Belgium, Russia, and Spain, and gain experience with sophisticated instrumentation, computational fluid dynamics simulations, data interpretation, forecasting, and global modeling.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该现场活动包括测试航班，以证明以前在NSF/NCAR Gulfstream v Research Aircraft上飞行的仪器。它还包括解决几种科学假设的飞行，包括研究对流层上层和下层平流层下部（UTL）的臭氧损失。这项研究结果是从UTLS中飞行的新仪器收集的结果，预计将显着提高该地区化学的科学理解。该项目将测试先进的仪器，以及适合于测量可凝结蒸气和环境离子对GV研究飞机的固定蒸汽和环境离子的新设计的层流入口，以实现以下目标：同时对气体和颗粒碘的飞机测量； （2）碘酸（HIO3）是一种可扩展的可凝结蒸气，可通过飞机在UTL中首次测量碘颗粒和驱动碘分配的变化； （3）同时测量环境离子（数量和化学组成）将确定那些参与UTL离子诱导成核的可凝结蒸气。初始测试航班将在科罗拉多州进行，此后，计划从Kona Hawaii进行有限数量的（〜3-6）探索性科学飞行，以展示飞机有效载荷的科学准备，评估仪器性能并为Mauna Loa Perservoration（MLO）的长期测量提供信息，以准备未来的运动。 MLO上方进行的飞机测量以及MLO上最大仪器仪器的碘氧化物（IO）自由基测量结果将使MLO上方IO的垂直轮廓的性质和形状表征。该项目包括与来自美国三个国家实验室，一名外国大学和5个外国国家实验室的科学家的合作。四名研究生和三个博士后将与美国，德国，比利时，俄罗斯和西班牙的11个不同机构的科学家进行互动，并在复杂的仪器，计算流体动力学模拟，数据解释，预测和全球建模方面获得经验，这反映了NSF的法定任务和Intelpriation的范围。
