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

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.
