Building a decade-long time series of Arctic atmospheric measurements

人类活动已经并正在造成我们大气层的变化。这些变化正在影响并将继续影响地球上的生活质量。国际上已将臭氧层破坏和气候变化这两个重要而相关的变化确定为本世纪大气科学面临的两大“重大挑战”。为了应对这些巨大的挑战，我的研究小组在加拿大北极地区进行测量，研究地球大气的化学成分及其随时间的变化。 需要进行长期测量，以了解我们大气层中发生的变化。这项北方研究将以过去对北极高纬度（80 N）大气的测量为基础，建立一个长达十年的关于臭氧层消耗和气候变化所涉及的关键化学品的数据集。测量将在春季进行，这是臭氧破坏最严重的时候。它们将被用来研究空间和地面上的仪器如何“看到”大气层中发生的事情。 这些结果将用于确定如何在北极地区最好地使用便携式仪器，以提高加拿大的大气测量能力，并进一步了解臭氧层的变化。 该北方研究补充材料将用于支持努纳武特（80 N，86 W）尤里卡的年度测量活动，以收集本项目所需的数据。 它还将支持一项教育和培训计划。 这将涉及学生在坚决湾在作出自己的测量大气和比较他们的结果与那些从尤里卡。

Human activity has caused and is causing changes in our atmosphere. These changes are affecting, and will continue to affect, the quality of life on Earth. Two important and related changes, ozone depletion and climate change, have been identified internationally as two of the "grand challenges" for atmospheric science in this century. To address these grand challenges, my research group makes measurements in the Canadian Arctic to study the chemical composition of the Earth's atmosphere and how it is changing with time. Long-term measurements are required to understand the changes occurring in our atmosphere. This Northern research will build on past measurements of the high Arctic (80 N) atmosphere to create a ten-year long data set of the key chemicals involved in depletion of the ozone layer and in climate change. The measurements will be made during springtime, the time when ozone destruction is greatest. They will be used to investigate how instruments in space and on the ground "see" what is happening in the atmosphere. These results will be used to determine how a portable instrument can be best used in the Arctic to increase Canadian atmospheric measurement capabilities and to further our understanding of the changing ozone layer. This Northern Research Supplement will be used to support yearly measurement campaigns in Eureka, Nunavut (80 N, 86 W) to collect the data needed for this project. It will also support an education and training program. This will involve students in Resolute Bay in making their own measurements of the atmosphere and comparing their results to those from Eureka.
