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. \n\nEnhancement 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. \n\nData 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. \n\nA daily file of 5-minute average calculated bulk fluxes are generated shortly after 0000UTC and provided to eMII.\n\nThe 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整体海气通量数据。

“船舶志愿观测船（Ships of Opportunity, SOOP）海气通量（Air Sea Flux, ASF）增强项目”中的“南方探测者号（Southern Surveyor）”，会在澳大利亚周边海域的科学考察航次中采集沿途气象与海洋学观测数据。

观测数据流将汇入现有船舶数据管理系统，并通过卫星每3小时向澳大利亚回传数据。所有观测数据将由澳大利亚气象局（Bureau of Meteorology）完成质量控制，并采用COARE整体通量算法（COARE Bulk Flux algorithm）计算海气通量。

每日协调世界时（UTC）0000时后不久，系统将生成包含5分钟平均海气通量计算结果的日数据文件，并推送至eMII平台。

本数据集以NetCDF格式文件存储，包含经过质量控制的原始气象观测输入数据，以及计算得到的海气通量数据。海气通量采用COARE整体通量算法3.0版（COARE Bulk Flux algorithm version 3.0）进行计算。对于以下要素，将从多数据流中选取对应观测数据：风速采用迎风仪器观测值；气温与湿度采用迎风仪器观测值；短波辐射取最大值，长波辐射取最小值。其余输入观测数据还包括海表温度（Sea Surface Temperature, SST）与大气压强。计算得到的海气通量要素包括感热通量、潜热通量、出射长波辐射通量、出射短波辐射通量以及降水热通量，同时包含计算得到的表皮海表温度（skin SST）数据。数据附带标记字段，用于标识计算通量时所采用的传感器（当存在多台可用传感器时）。由于仅在获取合格数据时才会计算海气通量，因此本数据集不附带质量控制标记字段。
