Development of Improved and Verified GCM Atmospheric Ice Radiation and Microphysics Parameterizations Using SHEBA data

该项目是北极海洋表面热量收支项目综合提案的一部分。 SHEBA项目目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，一艘破冰船冻结在博福特和楚科奇海的冰层中，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全年数据，将用于改进海冰对全球变暖反应的模型参数化。该项目将利用飞机数据来研究冰晶尺寸/形状对热平衡的云辐射反馈部分中的热辐射特性的作用。 云辐射反馈的新的平行谱线化在确定总的热平衡方面将是非常重要的。这一项目的活动是一项重要的努力，目的是加强SHEBA研究项目的成果，这些研究项目旨在改进气柱、中尺度和大气环流模型，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 utilize aircraft data to examine the role of ice crystal size/shape on the heat radiation properties in the cloud-radiation feedback component of the heat balance. New parameritizations of cloud-radiation feedbacks will be very important in determining overall heat balance. 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.
