项目摘要

The West Antarctic Ice Sheet (WAIS) is a rapidly warming region of the Earth. Its stability under projected warming scenarios is inextricably linked with future global sea level rise. There have been only modest ground based atmospheric science or climatological field observations collected in West Antarctica since that undertaken during the era of the 1957 International Geophysical Year. Satellite imagery and meteorological reanalysis indicate that West Antarctica is highly susceptible to continental advection of warm and moist maritime air and cloud cover, depending on the location and strength of climatological low pressure cells in the Amundsen, Ross, and Bellingshausen Seas. There is a need to quantify the role of these changing air masses have on the surface energy balance, including radiation components and cloud radiative forcing terms, and to identify distant teleconnections with lower latitudes, such as the North Atlantic and the tropics. The research proposed herein, at McMurdo and at WAIS divide, is organized in two thrusts: (1) Empirical determination of the energy balance on the WAIS divide site throughout a 75-day (austral summer) observing period, accounting for meteorological factors governing the local energy balance, and including exploration of teleconnections with lower latitudes, and, (2) Determination of the major categories of meteorological conditions that give rise to recurring types of cloud cover, including mixed phase clouds, and aerosol abundance over Ross Island, over an annual cycle. These measurement campaigns will be organized around the detailed protocols and advanced observing facilities enabled by the DOE ARM mobile facility (Department of Energy ? Atmospheric Radiation Measurement program). These extensive and advanced ARM microphysical data will also be used to assess how well current polar-optimized regional climate models simulate observed high latitude cloud cover.The AWARE campaign also will provide a hands-on opportunity to help high school teachers adapt to the new Next Generation Science and Engineering Standards (NGSS). AWARE science team members will also participate in annual teacher training workshops at Scripps Institution of Oceanography, involving selected San Diego Unified School District (SDUSD) master teachers.

南极冰盖（WAIS）是地球迅速变暖的地区。它在预计的变暖场景下的稳定性与未来的全球海平面上升密不可分。自从1957年国际地球物理年代时期进行以来，南极西部收集了基于地面的大气科学或气候田间观察。卫星图像和气象重新分析表明，西南极西部非常容易受到大陆的潮湿和潮湿的海洋空气和云层的对流，这取决于阿蒙森，罗斯和贝林斯豪森海的气候低压细胞的位置和强度。有必要量化这些变化的空气质量在表面能量平衡中的作用，包括辐射组件和云辐射强迫术语，并鉴定出具有较低纬度的远距离连接，例如北大西洋和热带。 The research proposed herein, at McMurdo and at WAIS divide, is organized in two thrusts: (1) Empirical determination of the energy balance on the WAIS divide site throughout a 75-day (austral summer) observing period, accounting for meteorological factors governing the local energy balance, and including exploration of teleconnections with lower latitudes, and, (2) Determination of the major categories of meteorological conditions that give rise to每年的周期，包括混合相云和罗斯岛上的气溶胶丰度，包括混合相云和气溶胶丰度。这些测量活动将围绕DOE ARM移动设施（能源部？大气辐射测量计划）实现的详细协议和高级观察设施组织。这些广泛的高级手臂微物理数据还将用于评估当前极地优化的区域气候模型如何模拟观察到的高纬度云覆盖率。意识的科学团队成员还将参加Scripps海洋学研究所的年度教师培训研讨会，涉及选定的圣地亚哥统一学区（SDUSD）大师教师。
