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. The data originally collected by these researchers provides an essential dataset of ice-surface observations of the atmospheric boundary level for use in improving large-scale models that require better parameterization of cloud-radiation and surface-albedo feedbacks for predicting the response of Arctic sea ice to global warming. The project involves analysis and quality control of surface-level data and production of a time-series of surface heat flux. The data will be incorporated into models of the atmospheric boundary layer and used to compare to data sets of surface parameters collected by aircraft over flights. The results of this project will be used in conjunction with other projects to enhance mesoscale and General Circulation Models (GCMs) that facilitate better simulations of the Arctic sea ice response to projected global warming trends.

该项目是北冰洋地表热量预算项目综合提案的一部分。SHEBA项目目前阶段的目标是利用一项为期一年的试验期间收集的数据，在该试验期间，一艘冻结在波弗特海和楚科奇海冰包中的破冰船被用作数据收集平台。收集了与海洋-冰-大气系统反馈有关的整个年度周期的数据，并将用于改进海冰对全球变暖反应的模式参数。这些研究人员最初收集的数据提供了大气边界水平的冰面观测的基本数据集，用于改进需要更好地对云辐射和地表反照率反馈进行参数化以预测北极海冰对全球变暖的反应的大型模式。该项目涉及地表数据的分析和质量控制以及地表热通量时间序列的制作。这些数据将被纳入大气边界层模型，并用于与飞机在飞行中收集的地面参数数据集进行比较。该项目的成果将与其他项目结合使用，以加强中尺度和一般环流模式，以便更好地模拟北冰洋海冰对预测的全球变暖趋势的反应。
