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

自2010年以来，“峰会能量、云、大气状态和降水综合表征”项目一直在格陵兰峰会站运行一套先进的地面仪器，用于观测云、降水和大气结构。该项目大大增进了对云的特性、辐射和表面能以及格陵兰冰盖上的降水过程的了解，同时还支持基于过程的模型评价、开发新的测量技术、对多个卫星测量和飞机飞行任务进行地面比较以及为天气预报模型提供无线电探空仪业务数据。这里将扩大原来的工作，延长两年的核心ICECAPS工作，包括气溶胶云实验（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上空气溶胶-云的相互作用以及它们如何影响表面能量收支，2）提供观测数据，作为极地预报年（YOPP）的一部分，用于数值模式评估这个项目是一个国际合作项目，通过美国国家科学基金会的北极观测网络和一个英国的一个气溶胶研究小组自然环境研究理事会。

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.
