Raine Island Automated Marine Weather And Oceanographic Station

This dataset contains meteorological data from Raine Island, Great Barrier Reef, from August 2012. The weather station is located on the Raine Island tower under a project with the Queensland Department of Environment and Resource Management (DERM). These data are collected to support scientific research at AIMS and DERM, data are part of a study into the breeding success of turtles on Raine Island. Data are made available on request to other researchers and to the public. The weather station is an AIMS Mk5 System.Data recorded: Barometric Pressure, Air Temperature, Wind Direction True (vector averaged), Wind Speed True (30 min average) and Humidity using a Vaisala WXT-520 weather station.Addditional data collected includes ground water levels and temperatures using bore-hole sensors along with video and still cameras to record turtle movements.1. Operation and Weather SensorsThe weather stations collect and store data in electronic memory every half-hour. A central base station calls each remote station regularly using a satellite link. Remote stations store data for 21 days. Features such as automatic operation, remote control, remote time setting, built in diagnostics, have been developed and incorporated.The sensors are a key part of a weather station. The station uses a Vaisala WXT520 weather station with additional sealing.2. System AccuracySystem accuracy is calculated as the sum of errors caused by: * Calibration * Interchanging sensors * Drift with time * Effects of an ambient temperature range from 0-40 degrees C.

本数据集包含2012年8月取自大堡礁雷恩岛（Raine Island）的气象观测数据。该气象站依托昆士兰州环境与资源管理部（Queensland Department of Environment and Resource Management, DERM）的项目，设置于雷恩岛塔楼之上。本数据集采集的数据旨在支撑澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）与昆士兰州环境与资源管理部（DERM）的科学研究，属于雷恩岛海龟繁殖成功率专项研究的组成部分。本数据集可应其他研究人员及公众的申请对外提供。该气象站为澳大利亚海洋科学研究所（AIMS）Mk5型观测系统。

观测记录的参数包括：气压、气温、真风向（矢量平均）、真风速（30分钟平均）以及相对湿度，观测设备为维萨拉（Vaisala）WXT-520气象站。额外采集的数据包括：通过钻孔传感器获取的地下水位与水温，以及用于记录海龟活动的视频与静态图像采集设备。

1. 运行机制与气象传感器
气象站每半小时将观测数据存储至电子内存中。中央基站通过卫星链路定期轮询各远程气象站。远程气象站可本地存储数据达21天。该系统集成了自动运行、远程控制、远程时间校准以及内置诊断等功能模块。

传感器是气象站的核心组成部分，本观测站采用加装密封防护的维萨拉WXT-520气象站传感器。

2. 系统精度
系统精度通过以下各项误差的总和进行计算：
* 校准误差
* 传感器更换误差
* 随时间产生的漂移误差
* 0至40摄氏度环境温度范围带来的影响误差。
