Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forward are now possible with modest investment. This project will conduct and combine observations from the recently acquired marine vessel, RV Investigator, and the collocated airborne and surface observations to understand the structure and evolution of the unique, pristine SO boundary layer and to evaluate satellites and climate models.

卫星产品和气候模式在南大洋（SO）的能量和水收支方面都有很大的偏差。这是对SO大气边界层的结构和动力学缺乏了解的直接后果，这是由于无法在这种恶劣的环境中进行必要的观测。由于新的澳大利亚研究基础设施的可用性，现在可以通过适度的投资向前迈出大步。该项目将进行并联合收割机从最近获得的海洋船只，RV调查，并配置空中和地面观测，以了解独特的，原始SO边界层的结构和演变，并评估卫星和气候模型。
