This project is part of an integrated set of proposals for the Surface Heat Budget of the Arctic (SHEBA) Ocean project. The goal of the current phase of the SHEBA project is to use data collected during a one year experiment during which an icebreaker frozen into the ice pack of the Beaufort and Chukchi Seas was used as a platform for data collection. A full annual cycle of data relating to feedbacks of the ocean-ice-atmosphere system was collected and will be used to improve model parameterizations of sea ice response to global warming. This project will conduct quality control analyses of aircraft data taken during the field program. The data will provide information about the ice/water in the clouds and, therefore, will be critical for determining the cloud properties affecting cloud radiation feedbacks in the heat budget equation. The activities of this project are an essential effort to enhance the outcome of the SHEBA research projects designed to improve column, mesoscale and General Circulation Models (GCMs) that facilitate better simulations of the Arctic sea ice response to projected global warming trends.

该项目是北极海洋表面热收支（SHEBA）项目综合提案的一部分。SHEBA项目当前阶段的目标是使用在为期一年的实验中收集的数据，在此期间，一艘被冻结在波弗特海和楚科奇海的浮冰中的破冰船被用作数据收集的平台。收集了与海洋-冰-大气系统反馈有关的完整的年循环数据，这些数据将用于改进海冰对全球变暖响应的模式参数化。该项目将对现场项目中获取的飞机数据进行质量控制分析。这些数据将提供有关云中冰/水的信息，因此，对于确定影响热收支方程中云辐射反馈的云特性将是至关重要的。该项目的活动是加强SHEBA研究项目成果的重要努力，该项目旨在改进柱状、中尺度和环流模式（GCMs），从而更好地模拟北极海冰对预估全球变暖趋势的响应。
