RV Investigator Voyage IN2024_T01 Underway (UWY) Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2024_T01, titled "Fremantle to Hobart, 2024 Transit." The voyage took place between March 9, 2024 and March 20, 2024 (AEST), departing from Fremantle and returning to Hobart.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.

本记录描述了从海洋国家设施（Marine National Facility, MNF）的“调查者号”（RV Investigator）航次IN2024_T01中获取的走航数据（Underway, UWY），该航次标题为“2024年弗里曼特尔至霍巴特航渡”。本次航次于2024年3月9日至2024年3月20日（澳大利亚东部标准时间，AEST）开展，从弗里曼特尔出发并最终返回霍巴特。
标准走航数据为连续采集记录，包含以下三类内容：
1. 导航数据（Navigation, NAV）：纬度、经度、航速、航向、对地航向、陀螺罗经以及多普勒计程仪（双GPS仪器）；
2. 温盐计（Thermosalinograph, TSG）：海水盐度、流量、水温、荧光强度、二氧化碳分压（pCO2）以及Optode/溶解氧传感器数据；
3. 大气气象数据（Atmospheric, MET）：湿度、风速与风向（风标与超声风速仪）、辐射计/海表温度、总日射表/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨、臭氧以及痕量气体（左舷与右舷配套仪器）。
经质量控制的“调查者号”走航气象与海表温度数据已提交至综合海洋观测系统（Integrated Marine Observing System, IMOS）澳大利亚海洋数据网络（Australian Ocean Data Network, AODN）及其他全球数据仓储与分发机构，并供澳大利亚气象局（Bureau of Meteorology, BoM）用于卫星海表温度验证工作。
近实时未处理数据可通过“走航数据可视化工具”链接获取。
本数据集已完成处理（含质量控制），并由澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, 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）完成归档。
数据集提供以下时间分辨率的文件：5秒（NetCDF格式）、5秒、10秒、1分钟及5分钟（ASCII格式）。
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（QC flags）。有关本数据集的更多信息，请参阅本航次的航次总结报告及/或数据处理报告。
