I have been working on modelling the chemistry of the atmosphere six and a half years, in my current job and for my PhD. Having experience with Lagrangian and Eulerian models of differing complexity and resolution, I understand that there are many different types of modelling tools, which are each useful for tackling different problems. I currently use a global chemical transport model (pTOMCAT) to investigate the role of nighttime oxidation in the UK region and globally, as part of the NERC-funded project RONOCO (Role Of Nighttime chemistry in controlling the Oxidising Capacity of the atmosphere). This project has combined aircraft measurements from around the UK (focusing on pollution plumes from major cities) with various chemical models, with the aim of understanding the contribution of nighttime oxidation. During my PhD, I used the Lagrangian photochemical model CiTTyCAT to study the different processes influencing the secondary pollutant ozone, in particular during inter-continental transport. I am currently also using the Met Office’s dispersion model, NAME, to investigate Arctic methane emissions sources. This is part of the MAMM (Methane in the Arctic: Measurements and Modelling) project, in which I have a role in flight planning, running NAME, and as the knowledge exchange (KE) contact. I am working with the British Antarctic Survey, who are co-ordinating the KE for NERC’s Arctic Research Programme (of which MAMM is a part). I have a keen interest in politics, and firmly believe in evidence-based policy. It is clear that in the field of air quality and the environment, science has an important role to play in informing policy. I also appreciate that despite the limitations of our scientific understanding, policy decisions must be made based on the best evidence available. Therefore, understanding the context and communicating the salient points of any research is essential. This became clear to me when I worked at the Institute of Physics as a communications officer. My role required me to read scientific papers and write press releases highlighting the wider importance of physics research. I also wrote press releases about the policy position of the Institute of Physics, for example in relation to science education, or responses to government consultations. As one of four main mission scientists, during the RONOCO field campaign (July 2010 and January 2011)I was part of a team responsible for planning and running flights on the UK research aircraft, which was based at East Midlands Airport for the field work. This role required assessing weather and air quality forecast information, and deciding where to fly to best meet our scientific and logistical needs. We worked well as a team, with one scientist taking responsibility for the final planning and running of each flight. This involved keeping all the instrument scientists (approximately 15 people) informed about the status of the flights, liaising with the pilots to plan the flights, and making decisions during the flight itself. I feel that I responded well to the extreme time-pressure and intensive working period, and really enjoyed working with so many different people (scientists, pilots, engineers, flight managers, Met Office weather forecasters) and juggling the different priorities.

在我目前的工作和博士学位中，我一直致力于大气化学建模六年半，拥有不同复杂度和分辨率的拉格朗日和欧拉模型的经验，我知道有许多不同类型的建模工具。作为 NERC 资助的 RONOCO 项目（角色）的一部分，我目前使用全球化学品运输模型 (pTOMCAT) 来研究夜间氧化在英国地区和全球的作用。控制大气氧化能力的夜间化学）该项目将英国各地的飞机测量结果（重点关注主要城市的污染羽流）与各种化学模型相结合，旨在了解夜间氧化的贡献。博士期间，我使用拉格朗日光化学模型 CiTTyCAT 研究影响二次污染物臭氧的不同过程，特别是在洲际运输过程中，我目前也在使用英国气象局的扩散模型， NAME，北极甲烷排放源。这是 MAMM（北极甲烷：测量和建模）项目的一部分，我在该项目中负责飞行规划、运行 NAME，并担任知识交流 (KE) 联系人。我正在与英国南极调查局合作，他们正在协调 NERC 北极研究计划的 KE（MAMM 是该计划的一部分），我对政治非常感兴趣，并且坚信基于证据的政策。很明显，在空气质量和环境领域，科学在为政策提供信息方面发挥着重要作用，我也意识到，尽管我们的科学理解存在局限性，但政策决策必须基于现有的最佳证据。当我在物理研究所担任通讯官员时，我清楚地认识到这一点至关重要，我的职责要求我阅读科学论文并撰写强调物理学更广泛重要性的新闻稿。我还撰写了有关研究所政策立场的新闻稿。物理学，例如与科学教育相关的内容，或对政府咨询的回应 作为 RONOCO 实地活动期间（2010 年 7 月和 2011 年 1 月）的四位主要任务科学家之一，我是负责规划和运行飞行的团队的一员。英国研究飞机驻扎在东米德兰机场进行实地工作，这一任务需要评估天气和空气质量预报信息，并决定飞往哪里才能最好地满足我们的科学和后勤需求。科学家承担责任每次飞行的最终规划和运行，包括让所有仪器科学家（大约 15 人）了解飞行状态，与飞行员联络以计划飞行，并在飞行过程中做出决定。我对极端的时间压力和密集的工作时间反应得很好，并且非常喜欢与这么多不同的人（科学家、飞行员、工程师、飞行经理、气象局天气预报员）一起工作并处理不同的优先事项。
