Mineral dust is now established as having a key influence in a wide range of biogeochemical cycles, and as a significant player within the Earth system. While most research on dust has been undertaken in the desert low latitudes, the operation of high latitude regions as important dust sources has only recently been appreciated. This importance is especially acute because dust generated in high latitude regions may have local impacts on particularly sensitive environmental and ecological systems (e.g. cryosphere, Arctic lake systems). While low latitude dust research has been well-informed by satellite studies, a number of challenges has meant the full potential of using remote sensing to better understand dust processes at the high latitudes has not yet been realised. This PhD will tap the diverse and exciting range of Earth Observation resources that now exist, applying them to examine dust activity at different temporal and spatial scales in a global study of the high latitude regions. The project offers an excellent chance to develop high level expertise and experience in a wide range of satellite and climate datasets, as well as GIS techniques, and apply them to better understanding land-atmosphere interactions in the high latitude environments.

矿物尘埃现在被确定为在广泛的生物地球化学循环中具有关键影响，并在地球系统中发挥重要作用。虽然对尘埃的大多数研究都是在沙漠低纬地区进行的，但高纬度地区作为重要尘埃源的运作直到最近才得到重视。这一重要性尤其严重，因为高纬度地区产生的粉尘可能对特别敏感的环境和生态系统(如冰冻圈、北冰洋湖泊系统)产生局部影响。虽然卫星研究为低纬尘埃研究提供了充足的信息，但一些挑战意味着利用遥感更好地了解高纬度尘埃过程的全部潜力尚未实现。这一博士学位将利用目前存在的各种令人兴奋的地球观测资源，应用它们在高纬度地区的全球研究中检查不同时间和空间尺度上的尘埃活动。该项目提供了一个极好的机会，可以在各种卫星和气候数据集以及地理信息系统技术方面发展高水平的专门知识和经验，并将其应用于更好地了解高纬度环境中的陆地-大气相互作用。
