IMOS - Deep Water Moorings - Air Sea Flux Station (ASFS) Sub-Facility

海气通量站子设施负责测量海面实时气象和海洋学条件的公海系泊。 特别是，这些观测站提供关于海气热量和水分通量的数据，这些数据与气象数据结合起来，对气候变化研究至关重要。 海气通量观测站提供的连续时间序列特别重要，因为控制热量和水分通量交换的许多过程在很大的时间尺度上都表现出可变性。ASFS的目标是在近实时的基础上提供高质量的海气通量测量。<br /> <br /> 观测数据由南大洋通量站（SOFS）获得，该站位于塔斯马尼亚西南部的亚南极地区（46.75S 141E）。SOFS系泊系统有两套辐射计、温度和湿度传感器、降水量计和声波风速计。<br /> <br /> 数据通过卫星定期传回澳大利亚。气象局对观测进行质量控制，并使用COARE Bulk Flux算法计算海气通量。在协调世界时0200点后不久，生成了观测值和计算的总通量的每小时平均值的每日文件，并通过IMOS海洋门户网站提供。

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.
