Collaborative Research: EAGER--Deployment of a New Photofragmentation Laser Induced Fluorescence (LIF) Nitrous Acid (HONO) Measurement on FIONA

EUROCHAMP(调查大气过程的欧洲模拟实验室一体化)将于2010年5月在西班牙巴伦西亚的EUPHORE实验室举行亚硝酸观测的正式国际比对，调查人员已被邀请参加。由于其高灵敏度和无已知干扰，PF-LIF(光碎裂-激光诱导荧光)是一种特别理想的菲奥纳测量技术。调查人员计划在急切的情况下参加菲奥纳的活动，因为在部署菲奥娜之前时间很短。亚硝酸，HONO，是大气化学中的关键物种。它在近紫外光中迅速光解，产生羟基自由基OH和一氧化氮NO。···然而，对HONO的行为的理解是不完整的。更好地理解这一重要分子的一个关键组成部分是确保研究界能够准确地测量它。这是HONO仪器所在的佐治亚理工学院和路易斯安那大学门罗分校(ULM)共同努力的结果。乌尔姆将提供现场校准和验证仪器，以及部署和建模专业知识。考虑到2010年年中的菲奥纳日期，由于时间原因，并行工作很重要。ULM和GA Tech之间合作的教育影响将使ULM具有高度积极性和自律的本科生获得新技术的经验和机会；接触当前大气化学领域的问题；并培养研究所需的批判性思维技能。与Gergia Tech这样的大型研究型大学的互动提供了获得ULM无法提供的机会的途径。这名学生将被期望对科学做出贡献。路易斯安那大学门罗分校位于密西西比河下游三角洲地区，该地区历史上是一个经济上处于不利地位的地区。UM致力于成为密西西比河下游三角洲公民通向多样化学术学习的门户。

EUROCHAMP (Integration of European Simulation Chambers for Investigating Atmospheric Processes) is holding the Formal Intercomparison of Observations of Nitrous Acid (FIONA) at the EUPHORE chambers in Valencia, Spain, in May 2010, and the investigators have been invited to participate. Because of its demonstrated high sensitivity and freedom from known interferences, PF-LIF (photofragmentation - laser induced fluorescence) is a particularly desired measurement technique for FIONA. The investigators plan to attend FIONA under EAGER because of the compressed timeframe prior to deployment for FIONA . Nitrous acid, HONO, is a critical species in the chemistry of the atmosphere. It photolyzes rapidly in the near ultraviolet to produce the hydroxyl radical, OH, and nitric oxide, NO. OH is the primary oxidant in the atmosphere and drives the bulk of atmospheric chemistry; NO, in the presence of volatile organic species, catalyzes the production of OH and thereby ozone. However, understanding of the behavior of HONO is incomplete. A key component to better understanding this important molecule is to ensure that the research community can measure it accurately. This is a joint effort between the Georgia Institute of Technology, where the HONO instrument exists, and the University of Louisiana at Monroe (ULM). ULM will contribute a field calibration and validation instrument, and deployment and modeling expertise. Working in parallel is important for time reasons, given the mid-2010 FIONA date. The educational impact of collaboration between ULM and GA Tech will allow a highly motivated and self-disciplined undergraduate from ULM to have experience with and access to new technology; to gain exposure to current issues in atmospheric chemistry; and to develop critical thinking skills needed in research. Interaction with a large research university like Gergia Tech provides access to opportunities that ULM cannot provide. This student will be expected to contribute to the science. The University of Louisiana at Monroe is located in the Lower Mississippi Delta region which is historically an economically disadvantaged area. ULM is committed to serving as a gateway to diverse academic studies for citizens of the Lower Mississippi Delta.
