Research on the impacts of climate change and variability in polar regions focuses on the interactions between the polar sea ice and climate systems. In particular, more than thirty years of passive microwave imagery of almost daily coverage of the polar regions is used to determine sea ice concentration and ice motion. Upper air reanalysis data from the European Centre for Medium-Range Weather Forecasts are used to determine synoptic patterns of geopotential height and temperature as well as derived fields of vorticity and ageostrophic motion. In addition, radiation balance data are available. Statistical models are used to find associations in time and space that may provide insight into the formative processes in the Arctic.

极地地区气候变化和变异性影响的研究重点是极地海冰和气候系统之间的相互作用。特别是，三十多年来几乎每天覆盖极地地区的被动微波图像被用来确定海冰的密度和冰的运动。来自欧洲中期天气预报中心的高空再分析数据被用来确定位势高度和温度的天气模式以及导出的涡量场和非地转运动场。此外，还提供了辐射平衡数据。统计模型被用来寻找时间和空间上的关联，这些关联可能提供对北极形成过程的洞察。
