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

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) R.V. Tangaroa collects underway meteorological and oceanographic observations during its voyages in Sub-Antarctic. \n\nData streams are fed into the existing ship data management system, and broadcast via satellite back to New Zealand daily. 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（bulk air-sea fluxes）。

机会船测量强化项目（Ships of Opportunity, SOOP）-海气通量（Air Sea Flux, ASF）：汤加罗阿号研究船（R.V. Tangaroa）在亚南极海域航行期间，会采集沿途的气象与海洋观测数据。

观测数据流会被接入现有船舶数据管理系统，并每日通过卫星回传至新西兰。所有观测数据均由澳大利亚气象局（Bureau of Meteorology）完成质量控制，海气通量则通过COARE整体海气通量算法（COARE Bulk Flux algorithm）计算得到。

每日协调世界时0000时后不久，系统会生成包含5分钟平均海气通量计算结果的日数据文件，并交付至eMII平台。

本数据集以NetCDF格式文件存储，包含经过质量控制的输入气象观测数据与计算得到的海气通量。海气通量采用COARE整体海气通量算法3.0版（COARE Bulk Flux algorithm version 3.0）计算得到。对于多数据流输入的观测变量，选取规则如下：风速选用迎风传感器的观测值，气温与湿度同样选用迎风传感器的观测值；短波辐射取最大值，长波辐射取最小值。其余输入观测数据包括海表温度（Sea Surface Temperature, SST）与大气压强。计算得到的海气通量包含感热、潜热、出射长波辐射、出射短波辐射以及降水热通量。同时还包含计算得到的表皮海表温度（skin SST）数据。数据中附带标记字段，用于指示计算通量时所选用的传感器（当存在多个可用传感器时）。由于仅在观测数据质量合格时才会计算海气通量，因此本数据集不提供通量相关的质量控制标记。
