IMOS-SOOP-Air Sea Flux: Flux product from the Research Vessel Southern Surveyor

This dataset contains quality controlled meteorological observations and bulk air-sea fluxes. Enhancement of Measurements on Ships of Opportunity (SOOP) - Air Sea Flux (ASF) Southern Surveyor collects underway meteorological and oceanographic observations during scientific voyages in the oceans adjacent to Australia. Data streams are fed into the existing ship data management system, and broadcast via satellite back to Australia 3-hourly. The observations are quality controlled at the Bureau of Meteorology and air-sea fluxes calculated using the COARE Bulk Flux algorithm. A daily file of 5-minute average calculated bulk fluxes are generated shortly after 0000UTC and provided to eMII.The data is contained in NetCDF format files and consists of input QC'd meteorological observations as well as calculated air-sea fluxes. The fluxes are calculated using the COARE Bulk Flux algorithm version 3.0. Input observations are selected from multiple data-streams in the cases of; wind (upwind instrument selected); air temperature and humidity (upwind instrument selected), and short (maximum value used) and long-wave (minimum value used). Other input observations included are sea surface temperatures (SST) and air pressure. Calculated fluxes include, sensible heat, latent heat, outgoing long-wave, outgoing short-wave and heat due to precipitation. The calculated skin SST value is included. Flags are provided to indicate which sensor (when multiple are available) has been used as input to compute the flux. QC flags are not provided as fluxes are only computed when good data is available.本数据集包含经过质量控制的气象观测数据与总体海气通量数据。本项目依托澳大利亚南方调查船（Southern Surveyor）开展自愿观测船（Ships of Opportunity, SOOP）海气通量（Air Sea Flux, ASF）观测增强工作，在澳大利亚邻近海域的科学考察航次中采集走航式连续气象与海洋学观测数据。观测数据流被接入现有船舶数据管理系统，并通过卫星每3小时向澳大利亚本土回传一次数据。所有观测数据均由澳大利亚气象局完成质量控制，海气通量则通过COARE总体通量算法（COARE Bulk Flux algorithm）计算得到。每日世界时0点后不久，系统将生成包含5分钟平均海气通量的数据集文件，并提交至eMII。本数据集以NetCDF格式文件存储，包含经过质量控制的输入气象观测数据与计算得到的海气通量数据。海气通量的计算采用COARE总体通量算法3.0版本（COARE Bulk Flux algorithm version 3.0）。输入观测数据从多数据流中择优选取：风速、气温与湿度均选取上风方向仪器的观测结果，短波辐射取多台仪器观测的最大值，长波辐射则取最小值。其余输入观测数据还包括海表温度（Sea Surface Temperature, SST）与大气压力。计算得到的海气通量包括感热通量、潜热通量、出射长波辐射、出射短波辐射以及降水热通量。数据集同时包含计算得到的表皮海表温度值。数据集附带标识标签，用于说明通量计算时所选用的传感器（当存在多台可用传感器时）。由于仅当观测数据质量合格时才会计算海气通量，因此本数据集不附带质量控制标识标签。
