Application of SHEBA Data to Understanding and Simulating the Cloud-Radiation Feedback: Boundary Layer Cloud Microphysical Properties and Processes

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。该项目将对现场计划期间采集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，对于在热量平衡方程中确定影响云辐射反馈的云属性将是至关重要的。该项目的活动是加强SHEBA研究项目成果的一项重要努力，该项目旨在改进柱状、中尺度和一般环流模式，以便更好地模拟北极海冰对预测的全球变暖趋势的反应。

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.
