The Greenland Ice Sheet is a unique location in the Arctic. It rises from sea level to over 10,000 feet in elevation and is, by far, the largest topographic feature north of the Arctic Circle. Scientists have determined that the ice sheet is sensitive to climatic fluctuations. In spite of its uniqueness and importance, it is relatively under-studied compared to other locations on Earth. The Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) project has been measuring properties of the surface and atmosphere over Greenland since 2010. This long-term field campaign has allowed researchers to better understand how the atmosphere affects the ice sheet. In particular, the project has helped to determine the role that clouds and precipitation over Greenland play in modulating the mass and energy budgets of the ice sheet. These processes are essential for properly quantifying how much melt water is produced by the Greenland Ice Sheet, and how this contributes to global sea-level rise. As part of this new project, the instrument suite will be expanded to include an Aerosol-Cloud Experiment (ACE) through a partnership with researchers at the U.K. Natural Environment Research Council. ICECAPS-ACE will continue to make routine observations of the atmosphere, but includes two new major goals. First, ICECAPS-ACE will provide a better understanding of aerosol-cloud interactions over the Greenland Ice Sheet. Summit Station is a unique location to study such interactions because there are no significant local sources of cloud-active aerosols. Aerosols are tiny particles in the atmosphere that play a significant role in cloud formation. Knowledge of the interaction between aerosols and clouds is important for providing more accurate models of weather and climate over Greenland. Secondly, ICECAPS-ACE will provide a comprehensive suite of observations as part of the Year of Polar Prediction (YOPP) that can be used for the assessment of numerical models. It will also overlap with field activities of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) project, which offers an unprecedented focus by the operational modeling community on the Arctic system. The continuation of the ICECAPS field campaign will create a valuable 10-year dataset that documents changes from year-to-year from this unique location in Greenland.The Greenland Ice Sheet (GrIS) is of critical importance to human society because of its role in global sea-level rise, and it is melting at an accelerating rate. Providing a better understanding of the interactions between aerosols and clouds is of direct societal value because of their ultimate impact on the GrIS mass and energy budgets. Since 2010 ICECAPS has significantly advanced understanding of cloud properties, radiation and surface energy, and precipitation processes over the GrIS, while also supporting 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. The new ICECAPS-ACE will provide insight into the role that advective aerosol sources play in cloud and precipitation processes. The addition of the aerosol measurements will allow, for the first time, an investigation of how aerosols impact the surface energy and mass budgets of the central GrIS. Because of the importance of the GrIS to the Arctic, the ICECAPS project has been endorsed as a YOPP activity and will archive high-resolution data to be used for physical process-based model evaluation and verification that will focus on the surface energy budget, precipitation, and cloud-aerosol interactions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

格陵兰冰盖是北极的一个独特位置。它从海平面上升到超过 10,000 英尺的海拔，是迄今为止北极圈以北最大的地形特征。科学家已经确定冰盖对气候波动很敏感。尽管它具有独特性和重要性，但与地球上的其他地方相比，它的研究相对较少。自 2010 年以来，能量、云、大气状态和山顶降水的综合表征 (ICECAPS) 项目一直在测量格陵兰岛表面和大气的特性。这项长期的实地活动使研究人员能够更好地了解大气如何影响格陵兰岛。冰盖。特别是，该项目有助于确定格陵兰岛上空的云和降水在调节冰盖的质量和能量预算中所发挥的作用。这些过程对于正确量化格陵兰冰盖产生的融水量以及融水对全球海平面上升的影响至关重要。作为这个新项目的一部分，该仪器套件将通过与英国自然环境研究委员会的研究人员合作进行扩展，包括气溶胶云实验（ACE）。 ICECAPS-ACE 将继续对大气进行常规观测，但包括两个新的主要目标。首先，ICECAPS-ACE 将帮助人们更好地了解格陵兰冰盖上的气溶胶-云相互作用。峰会站是研究此类相互作用的独特地点，因为当地没有重要的云活性气溶胶来源。气溶胶是大气中的微小颗粒，在云的形成中发挥着重要作用。了解气溶胶和云之间的相互作用对于提供更准确的格陵兰天气和气候模型非常重要。其次，ICECAPS-ACE 将提供一套全面的观测数据，作为极地预测年 (YOPP) 的一部分，可用于评估数值模型。它还将与北极气候研究多学科漂流观测站（MOSAiC）项目的现场活动重叠，该项目为业务建模界提供了对北极系统前所未有的关注。 ICECAPS 实地活动的继续将创建一个有价值的 10 年数据集，记录格陵兰岛这个独特地点每年的变化。格陵兰冰盖 (GrIS) 对人类社会至关重要，因为它在全球海平面上升，并且正在加速融化。更好地了解气溶胶和云之间的相互作用具有直接的社会价值，因为它们最终对 GrIS 质量和能量预算产生影响。自 2010 年以来，ICECAPS 显着增进了对 GrIS 云特性、辐射和表面能以及降水过程的了解，同时还支持基于过程的模型评估、新测量技术的开发、多个卫星测量和飞机任务的地面比较以及运营用于天气预报模型的无线电探空仪数据。新的ICECAPS-ACE将深入了解平流气溶胶源在云和降水过程中发挥的作用。增加气溶胶测量将首次能够调查气溶胶如何影响中央 GrIS 的表面能量和质量预算。由于 GrIS 对北极的重要性，ICECAPS 项目已被批准为 YOPP 活动，并将存档高分辨率数据，用于基于物理过程的模型评估和验证，重点关注地表能量预算、降水该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
