RV Investigator Voyage IN2024_T02 Underway (UWY) Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2024_T02, titled "Transit to shipyard." The voyage took place between July 08, 2024 and July 22, 2024 (AEST), departing from Brisbane and returning to Singapore.Standard Underway data is continuously recorded, consisting of: (1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, Course Over Ground, Gyros, and Doppler Log (dual GPS instrument). (2) Thermosalinograph (TSG): Water Salinity, Flow-Rate, Temperature, Fluorescence, pCO2 and Optode/Oxygen. (3) Atmospheric (MET): Humidity, Wind Speed and Direction (vane and ultrasonic), Radiometer/Sea Surface Temperature, Pyranometer/Solar Radiation, Photosynthetically Active Radiation (PAR), Air Temperature, Air Pressure, Rain, Ozone and Trace Gases (port and starboard instruments).The quality-controlled RV Investigator underway meteorological and SST data are supplied to the IMOS AODN and other global data repositories and distributors, and made available for satellite SST validation by the Australian Bureau of Meteorology (BoM).Near real-time, unprocessed data are available via the link "Visualisation tool for Underway Data."This dataset has been processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Data are available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII format). Note: not all variables are quality controlled; please check for existing QC flags in the datasets. Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Reports for this voyage.

本记录描述了从澳大利亚国家海洋设施（Marine National Facility, MNF）“调查者号”（RV Investigator）科考船航次IN2024_T02（航次主题为“前往船厂航渡”）获取的船载连续观测（Underway, UWY）数据。该航次于2024年7月8日至2024年7月22日（澳大利亚东部标准时间，AEST）执行，从布里斯班出发，最终返回新加坡。
标准船载连续观测数据为连续采集序列，包含以下三类内容：
1. 导航数据（Navigation, NAV）：涵盖纬度、经度、航速、艏向、对地航向、陀螺罗经数据以及采用双GPS配置的多普勒计程仪观测数据；
2. 走航温盐仪（Thermosalinograph, TSG）：涵盖海水盐度、流量、水温、荧光强度、二氧化碳分压（pCO₂）以及Optode型溶解氧传感器观测数据；
3. 大气观测数据（Atmospheric, MET）：涵盖湿度、风速与风向（采用风向标与超声风速仪）、辐射计/海表温度（Sea Surface Temperature, SST）、总日射表/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨量、臭氧以及痕量气体（采用左舷与右舷两套观测仪器）。
经质量控制的“调查者号”船载气象与海表温度数据已提交至IMOS AODN（澳大利亚综合海洋观测系统海洋数据网络）及其他全球数据仓储与分发机构，并供澳大利亚气象局（Australian Bureau of Meteorology, BoM）开展卫星海表温度验证工作使用。
近实时未处理数据可通过“船载数据可视化工具”链接获取。
本数据集已完成处理与质量控制，并由澳大利亚联邦科学与工业研究组织（CSIRO）国家馆藏与海洋基础设施（National Collections and Marine Infrastructure, NCMI）信息与数据中心（Information and Data Centre, IDC）归档。数据提供5秒（NetCDF格式）、5秒、10秒、1分钟及5分钟（ASCII格式）四种时间分辨率版本。注意：并非所有变量均经过质量控制，请检查数据集中现有的质量控制标记。有关本数据集的更多信息，请参见本航次的航次总结报告及/或数据处理报告。
