Interaction of Air, Sea Ice, and Ocean Around Antarctica

地面气压、地面气温等关键观测量的观测网络是数值天气预报和气候模拟的基础。在南大洋和南极大陆周围的海冰上的这些观测仍然是地球上观测最差的地区。该提案提议通过部署若干漂流浮标，将测量能力（空间应用程序、卫星-空中和海上）、海冰运动和海洋温度扩展到200米深处），这些浮标是以北极冰浮标方案中常规使用的浮标为基础的。 除了它们在数值预报中的潜在用途（例如在USAP中使用的AMPS）外，所收集的数据还将与现有的再分析场进行比较，如NCEP/NCAR和ECMWF的工作。并提供给感兴趣的USAP研究人员。目标区域将包括阿蒙森海和罗斯海地区，特别是波吕纳斯，这可能有助于提高麦克默多地区的业务预报技能。拟议研究的其他影响包括通过牵头机构现有的教育意识方案进行公众宣传。

Weather observation networks of key observables such as surface air pressure (SAP) and surface air temperature (SAT) are the foundation of numerical weather prediction (NWP) and also of climate modeling. These observations in the Southern Ocean and the sea-ice around the Antarctic continent remain some of the most poorly observed regions of the planet. This proposal offers to extend measurement capabilities (SAP, SAT - air and sea), sea ice motion and ocean temperature to 200 m depth) through the deployment of a number of drifting buoys, based on those routinely used in the Arctic ice buoy program. As well as their potential use in NWP (e.g. AMPS, used operationally in USAP), the collected data will be compared to existing reanalysis fields such as the NCEP/NCAR and ECMWF efforts. and made avaialble to interested USAP researchers. Target areas will include the Amundsen and Ross Sea regions, especially polynas, which may serve to increase operational forecast skill in the McMurdo area. Other impacts of the proposed research include public outreach through existing educational awareness programs at the lead institution.
