The Air-Sea Flux Stations (ASFS) sub-facility is responsible for open-ocean moorings that measure real-time meteorological and oceanographic conditions at the sea surface. In particular, the stations provide data on air-sea heat and moisture fluxes, which, when combined with meteorological data, are essential for climate change research. The continuous time series provided by the air-sea flux stations are particularly important because many of the processes that control heat and moisture fluxes exchange show variability on a wide range of time scales. ASFS aims to deliver high quality air-sea flux measurements on a near real-time basis. <br /> <br /> Observations are obtained by the Southern Ocean Flux Station (SOFS) mooring in the Sub-Antarctic zone, south-west of Tasmania (46.75S 141E). The SOFS mooring has dual sets of radiometers, temperature and humidity sensors, precipitation gauges and sonic anemometers. <br /> <br /> Data are broadcast via satellite back to Australia routinely. The observations are quality controlled at the Bureau of Meteorology and air-sea fluxes calculated using the COARE Bulk Flux algorithm. Daily files of 1-hourly averages of the observations and calculated bulk fluxes are generated shortly after 0200UTC and made available via the IMOS Ocean Portal.

海气通量站（ASFS）子设施负责公海系泊，测量海面的实时气象和海洋状况。 特别是，这些站提供有关空气-海洋热量和水分通量的数据，这些数据与气象数据相结合，对于气候变化研究至关重要。 空气-海洋通量站提供的连续时间序列特别重要，因为许多控制热量和水分通量交换的过程在很大的时间尺度上表现出变化。 ASFS 旨在近乎实时地提供高质量的海气通量测量。 <br/> <br/> 观测数据是由停泊在塔斯马尼亚西南部亚南极地区（46.75S 141E）的南大洋通量站（SOFS）获得的。 SOFS系泊装置有双套辐射计、温度和湿度传感器、降水计和声波风速计。 <br/> <br/> 数据定期通过卫星传回澳大利亚。气象局对观测结果进行质量控制，并使用 COARE Bulk Flux 算法计算海气通量。每日 1 小时观测平均值和计算的总通量的每日文件在 0200UTC 后不久生成，并通过 IMOS 海洋门户提供。
