IMOS-SOOP-Air Sea Flux : Meteorological and SST Observations collected on the Research Vessel Aurora Australis

This dataset contains environmental observations as well as ship parameters (such as speed and direction).Enhancement of Measurements on Ships of Opportunity (SOOP)- Air Sea Flux (ASF) R.V. Aurora Australis collects underway meteorological and oceanographic observations during scientific and Antarctic resupply 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 30 minutes. 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 1-minute averages of the observations are generated shortly after 0000UTC and provided to eMII.The data is contained in NetCDF format files and consists of environmental observations as well as ship parameters (such as speed and direction). Wind is observed with two different sensors, and the relative (observed) and true (relative to fixed earth) wind speed and direction provided. Air temperature and humidity is observed on the port and starboard of the main mast. Short-wave (sunlight) and long-wave (infra-red radiation or heat, from sky and clouds) is also observed on the port and starboard side. Precipitation is observed with an optical rain-gauge and traditional siphon gauge from the foremast. Instrument meta-data and QC flags are also contained in the files.

本数据集包含环境观测数据与船舶参数（如航速与航向）。自愿观测船舶测量增强项目（Ships of Opportunity, SOOP）- 海气通量（Air Sea Flux, ASF）的研究船“极光南极号（R/V Aurora Australis）”，在澳大利亚周边海域开展科考与南极补给航行期间，采集航行过程中的气象与海洋学观测数据。数据流经现有船舶数据管理系统处理后，通过卫星每30分钟回传至澳大利亚。所有观测数据均由澳大利亚气象局完成质量控制，并通过COARE总体通量算法（COARE Bulk Flux algorithm）计算海气通量。协调世界时每日00:00过后不久，系统便会生成观测数据的1分钟平均值日文件，并提供给eMII平台。
本数据集以NetCDF格式文件存储，内容同样包含环境观测数据与船舶参数（如航速与航向）。该船配备两套不同的风速风向传感器，可输出相对（实测）风速风向与绝对（相对于固定地球坐标系）风速风向。主桅杆左舷与右舷均安装了空气温度与湿度传感器。短波（太阳光）与长波（源自天空与云层的红外辐射或热量）辐射也在主桅杆左右舷进行观测。前桅搭载了光学雨量计与传统虹吸式雨量计，用于观测降水。数据文件中同时包含仪器元数据与质量控制标记（QC flags）。
