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.

在现场、长期的大气温室气体测量界的一个主要问题是，我们坐在丰富的测量数据集上，没有时间或资源来检查它们。相反，我们忙于保持测量的运行，因为他们必须一天24小时、一周7天、一年365天运行-这与大多数大气科学家非常不同，他们在开始-停止活动的模式下工作，因此有机会‘喘口气’，分析他们的数据和写论文。这个问题在我们的社区中已经存在了至少几十年，严重阻碍了科学进步，也正在成为UEA/ENV的一个日益严重的问题。因此，这一博士生计划旨在采取措施，在UEA/ENV层面解决这一问题。这将通过让学生不专注于开展活动、安装新仪器或建立新的测量站(正如我们之前的学生所做的那样)来实现，而是利用我们现有的数据集。其中包括韦伯恩的二氧化碳、O2、CO和H2的9年记录，CH4的4年记录，以及N2O和SF6的3年记录。除了Weybourne，我们还有来自Mace Head(爱尔兰西海岸)的二氧化碳和O2的数据集，来自一艘从德国持续驶往阿根廷的集装箱船的CO2、O2和CH4的数据集，以及来自南极哈雷研究站的CO2、O2、CH4、N2O和CO的数据集。这个项目在很大程度上是一种数据挖掘活动，故意不是规定性的。学生将有机会看到数据将他们引向何方，并追逐自己的兴趣。但与此同时，监督团队将给予强有力的指导和指导，以确保学生不会犹豫不决，并确保他们选择的路径是可行的，并可在同行评议的文献中发表。韦伯恩是英国唯一的大气站，是欧盟‘综合碳观测系统-ICOS’的一部分，这对UEA来说是一个重大的成功，它不仅让我们能够接触到充满活力的国际社会，还让学生能够访问整个ICOS网络(整个欧洲约30个大气站)的大气数据集。此外，ICOS-大气每年举行两次会议，我们强烈鼓励学生每隔一次参加一次会议，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，并结识研究类似主题的其他博士生网络。有多种培训机会，例如，气象局为他们的“名字”大气传输模型举办了培训讲习班，ICOS为博士生举办了温室气体暑期学校。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让技能，因为学生将获得对最先进的乐器的理解。学生还将获得气体处理和复杂的校准程序的详细知识和理解。
