A major problem in the in-situ, long-term atmospheric greenhouse gas measurement community is that we are sitting on a wealth of measurement data sets, with no time or resources to examine them. Instead we are too busy keeping the measurements running, as they must run 24 hours a day, 7 days a week, 365 days a year - this is very different from most atmospheric scientists, who operate in start-stop campaign mode, and therefore have opportunities to 'catch their breath', analyse their data and write papers. This problem, which has existed for at least a couple of decades in our community, significantly hinders scientific advancement, and is also becoming a growing problem at UEA/ENV. Therefore, this PhD studentship aims to take steps to address this problem at the UEA/ENV-level. This will be achieved by having a studentship focussed not on running campaigns, setting up new instrumentation, or establishing a new measurement station (as our previous students have done), but rather, exploiting the existing data sets that we have. These include, at Weybourne, 9-year records of CO2, O2, CO and H2, a 4-year record of CH4, and 3-year records of N2O and SF6. In addition to Weybourne, we have data sets of CO2 and O2 from Mace Head (west coast of Ireland), CO2, O2 and CH4 from a container ship travelling continuously from Germany to Argentina, and CO2, O2, CH4, N2O and CO from Halley Research Station, Antarctica. This project is very much a data mining exercise, and is deliberately not prescriptive. The student will have the opportunity both to see where the data leads them, and to chase their own interests. But at the same time, strong direction and guidance will be given by the supervisory team, to ensure that the student does not flounder, and to ensure that their chosen path is both feasible and publishable in the peer-reviewed literature.Weybourne is the UK's only atmospheric station that is a part of the European Union's 'Integrated Carbon Observation System - ICOS', a major coup for UEA, which provides us access not only to a vibrant international community, but also gives the student access to the atmospheric data sets from the entire ICOS network (~30 atmospheric stations across Europe). In addition, ICOS-Atmosphere holds twice-yearly meetings, and we strongly encourage the student to attend every second meeting, that is, annually. This would allow the student to establish relationships with European and UK colleagues, as well as meet a network of other PhD students researching similar topics. Multiple training opportunities exist, for example, the Met Office holds training workshops for their 'NAME' atmospheric transport model, and ICOS hold summer schools on greenhouse gases for PhD students. Finally, the student will also be responsible for maintaining some of the instrumentation at Weybourne, specifically that instrumentation not presently covered by any research grants. This will broaden the student's transferable skills, as the student will obtain an understanding for state-of-the-art instrumentation. The student will also acquire detailed knowledge and understanding of gas handling and complex calibration procedures.

现场长期大气温室气体测量界的一个主要问题是，我们拥有大量的测量数据集，但没有时间或资源来检查它们。相反，我们太忙于保持测量运行，因为它们必须每天 24 小时、每周 7 天、每年 365 天运行 - 这与大多数大气科学家非常不同，他们在启停活动模式下运行，因此“喘口气”、分析数据和撰写论文的机会。这个问题在我们的社区中已经存在了至少几十年，极大地阻碍了科学进步，并且在 UEA/ENV 也正在成为一个日益严重的问题。因此，该博士生奖学金旨在采取措施在 UEA/ENV 层面解决这一问题。要实现这一目标，学生的重点不是开展活动、设置新仪器或建立新的测量站（就像我们以前的学生所做的那样），而是利用我们现有的数据集。其中包括韦伯恩 9 年的 CO2、O2、CO 和 H2 记录、4 年的 CH4 记录以及 3 年的 N2O 和 SF6 记录。除了韦伯恩之外，我们还有来自 Mace Head（爱尔兰西海岸）的 CO2 和 O2 数据集，来自从德国连续行驶到阿根廷的集装箱船的 CO2、O2 和 CH4，以及来自南极洲哈雷研究站。这个项目在很大程度上是一个数据挖掘练习，并且故意不规范。学生将有机会了解数据将他们引向何方，并追求自己的兴趣。但同时，导师团队也会给予强有力的指导和指导，以确保学生不会陷入困境，并确保他们选择的道路既可行又可以在同行评审的文献中发表。韦伯恩是英国的唯一的大气站，是欧盟“综合碳观测系统 - ICOS”的一部分，这是东英吉利大学的一项重大举措，它不仅为我们提供了接触充满活力的国际社区的机会，而且还为学生提供了接触大气的机会来自整个 ICOS 网络（欧洲约 30 个大气站）的数据集。此外，ICOS-Atmosphere 每年举行两次会议，我们强烈鼓励学生参加每两次会议，即每年一次。这将使学生能够与欧洲和英国的同事建立关系，并结识其他研究类似主题的博士生网络。存在多种培训机会，例如，英国气象局为其“NAME”大气传输模型举办培训研讨会，ICOS 为博士生举办温室气体暑期学校。最后，学生还将负责维护韦伯恩的一些仪器，特别是目前没有任何研究资助的仪器。这将扩大学生的可转移技能，因为学生将了解最先进的仪器。学生还将获得有关气体处理和复杂校准程序的详细知识和理解。
