The Centre for Polar Observation and Modelling: National Capability Science Programme April 2019 - March 2021

极地观测和模拟中心(CPOM)研究两极发生的影响我们气候、海洋、大气环流和海平面的过程。我们开发了陆地和海冰的卫星观测，将它们与数值模型结合起来，解释地球冰、海洋和大气如何相互作用并预测它们将如何演变。例如，结合数据和模型使我们能够改进对海冰的季节性预报和冰盖演变的预测，并解释气候变化的关键信号，如松岛冰川的动力不平衡、拉森冰架的稳定性、格陵兰冰川动力学的控制、北冰洋和南大洋的变化。我们领导国际努力量化极地冰盖导致的海平面上升，并预测其未来的贡献。我们与空间机构合作，为极地卫星飞行任务提供科学指导，我们制作和发布独特且广泛使用的地球海冰和冰盖厚度记录，我们支持英国地球系统模型中的陆地冰和海冰元素。我们的活动在国际上是杰出的，规模是十年的，并与BAS的科学优先事项密切一致。与BAS一起，我们的工作解决了NERC的核心战略，即长期和大规模地观察、监测和预测地球及其环境的行为。

The Centre for Polar Observation and Modelling (CPOM) studies processes occurring at the poles which affect our climate, oceans, atmospheric circulation and sea level. We develop satellite observations of land and sea ice, combining them with numerical models to explain how Earth's ice, oceans and atmosphere interact and to predict how they will evolve.Combining data and models has allowed us, for example, to improve seasonal forecasts of sea ice and projections of ice sheet evolution, and to explain key signals of climate change such as dynamical imbalance of the Pine Island Glacier, stability of the Larsen Ice Shelf, controls on Greenland glacier dynamics, variability in Arctic sea ice thickness, and variability in the Arctic and Southern Oceans.We lead international efforts to quantify sea level rise due to the polar ice sheets, and to predict their future contributions, we partner with space agencies to provide scientificleadership for polar satellite missions, we produce and distribute unique and widely-used records of Earth's sea ice and ice sheet thickness, and we support the land ice and sea iceelements of the UK Earth System Model. Our activities are internationally outstanding, decadal in scale, and closely aligned with BAS's science priorities. Together with BAS, our work addresses NERC's core strategy to observe, monitor and predict the behaviour of the Earth and its environment over long periods and across large scales.
