NSFGEO-NERC: The Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit,Aerosol-Cloud Experiment

峰顶能量、云、大气状态和降水综合表征项目（ICECAPS）自2010年以来在格陵兰峰顶站连续运行了一套复杂的地面仪器，用于观测云、降水和大气结构。该项目极大地促进了对格陵兰冰盖（GrIS）上云特性、辐射和地表能以及降水过程的理解，同时还支持基于过程的模式评估、新测量技术的开发、多卫星测量和飞机任务的地面比较以及天气预报模式的业务无线电探空数据。该项目将在原有工作的基础上扩展两年，扩展到ICECAPS的核心工作，并包括一个气溶胶云实验（ACE）。我们将通过追求两个主要目标来加强ICECAPS项目：1)更好地了解GrIS上气溶胶-云的相互作用以及它们如何影响地表能量收支；2)为数值模式评估提供观测数据，作为极地预测年（YOPP）的一部分。该项目是一个国际合作项目，由美国国家科学基金会的北极观测网络和英国自然环境研究委员会的气溶胶研究小组资助最初的ICECAPS研究人员。

The Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) project has continuously operated a sophisticated suite of ground-based instruments at Summit Station, Greenland since 2010 for observing 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), 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. Here will expand on the original work with a two-year extension to core ICECAPS work and include an Aerosol-Cloud Experiment (ACE). We will enhance the ICECAPS project by pursuing two primary goals: 1) provide a better understanding of aerosol-cloud interactions over the GrIS and how they impact the surface energy budget, and 2) provide observations that for numerical model assessment as part of the Year of Polar Prediction (YOPP).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 aerosol researchers through the U.K. Natural Environment Research Council.
