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.

地面气压(SAP)、地面气温(SAT)等关键观测值组成的气象观测网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少的一些地区。该提案提出，在北极浮标方案常规使用的浮标的基础上，通过部署若干漂流浮标，将测量能力(SAP、SAT--空气和海洋)、海冰运动和海洋温度扩展到200米深。收集的数据将与NCEP/NCAR和ECMWF等现有再分析领域进行比较，以及它们在NWP中的潜在用途(例如，在USAP中实际使用的AMPS)。并向感兴趣的USAP研究人员提供。目标区域将包括阿蒙森和罗斯海地区，特别是波利纳斯地区，这可能有助于提高麦克默多地区的业务预测技能。拟议研究的其他影响包括通过牵头机构现有的教育意识项目进行公众宣传。
