Overview: A three-year extension is proposed to the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) project. This project is an international collaboration that funds the original ICECAPS researchers through the U.S. National Science Foundation's Arctic Observing Network and a team of researchers at the University of Leeds through the U.K. Natural Environment Research Council. The ICECAPS project has continuously operated a sophisticated suite of ground-based instruments at Summit Station, Greenland since 2010 for observation of clouds, precipitation, and atmospheric structure. The project has significantly advanced the understanding of cloud properties, radiation and surface energy, and precipitation processes over the Greenland Ice Sheet (GrIS) during a period of rapid climate change. The project has supported numerous national and international collaborations in process-based model evaluation, development of new measurement techniques, ground comparisons for multiple satellite measurements and aircraft missions, and operational radiosonde data for weather forecast models. We propose to complement the ICECAPS Summit observatory by building, testing and deploying an additional observatory for measuring parameters of the surface mass and energy budgets of the GrIS. The observatory takes a novel approach for unattended, autonomous operations by supporting a suite of instruments that require moderate power and manageable internet bandwidth. The new observatory will be deployed in successive summers at Summit Station in the dry-snow zone and at Dye-2 in the percolation zone. If this pilot project is successful, a network of these observatories will be proposed for future deployment that will observe the processes of air parcels as they move along Lagrangian trajectories in southwestern Greenland.

概述：建议将首脑会议上的能量、云、大气状态和降水综合表征项目延长三年。该项目是一项国际合作，通过美国国家科学基金会的北极观测网络资助ICECAPS的原始研究人员，并通过英国资助利兹大学的一组研究人员。自然环境研究理事会。自2010年以来，ICECAPS项目一直在格陵兰Summit站运行一套先进的地面仪器，用于观测云、降水和大气结构。该项目极大地促进了对云的性质、辐射和表面能以及气候快速变化期间格陵兰冰盖上的降水过程的了解。该项目支持了在基于过程的模型评价、开发新的测量技术、多个卫星测量和飞机飞行任务的地面比较以及天气预报模型的业务无线电探空仪数据方面的许多国家和国际合作。我们建议通过建立、测试和部署一个额外的观测站来补充ICECAPS峰会观测站，以测量GrIS的表面质量和能量预算参数。天文台采用了一种新颖的无人值守的自主操作方法，支持一套需要中等功率和可管理的互联网带宽的仪器。新的观测站将在连续的夏季部署在干雪区的Summit站和渗滤区的Dye-2。如果这一试点项目取得成功，将提出一个由这些观测站组成的网络供今后部署，该网络将观测格陵兰西南部沿着拉格朗日轨迹移动的空气包裹的过程。
