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.

EUROCHAMP（欧洲大气过程研究模拟室一体化）将于2010年5月在西班牙瓦伦西亚的EUPHORE室举行亚硝酸观测正式相互比较，研究人员已应邀参加。 由于其表现出的高灵敏度和自由从已知的干扰，PF-LIF（光致碎裂-激光诱导荧光）是一个特别理想的测量技术FIONA。 研究者计划在EAGER下参加FIONA，因为FIONA部署前时间紧迫。 亚硝酸（HONO）是大气化学中的一种关键物质。 它在近紫外线下迅速光解，产生羟基自由基（OH）和一氧化氮（NO）。OH是大气中的主要氧化剂，驱动大气化学的大部分; NO在挥发性有机物质存在下催化OH的产生，从而产生臭氧。 然而，对HONO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仪器所在的格鲁吉亚理工学院和位于门罗的路易斯安那大学（乌尔姆）之间的共同努力。 乌尔姆将提供现场校准和验证工具，以及部署和建模专业知识。 鉴于2010年中期的《行动计划》日期，由于时间原因，平行工作很重要。 乌尔姆和GA Tech之间的合作的教育影响将允许一个高度积极性和自律的本科生从乌尔姆有经验，并获得新技术;获得接触大气化学当前的问题;并开发研究所需的批判性思维技能。 与像Gergia Tech这样的大型研究型大学的互动提供了乌尔姆无法提供的机会。 这个学生将被期望为科学做出贡献。位于门罗的路易斯安那大学位于下密西西比三角洲地区，历史上是一个经济落后的地区。 乌尔姆致力于为下密西西比三角洲的公民提供多样化学术研究的门户。
