Orpheus Island Weather Station installed on Sensor Relay Pole 3

A Vaisala WXT520 integrated weather station has been installed on RP3, a 6m steel pole, which has been installed at Orpheus Island on the central Great Barrier Reef. The sensor-relay pole provides a platform for the installation of sensors to measure and monitor water conditions at Orpheus Island. The pole has real time communications using 900MHz spread spectrum radio back to a base station on Orpheus Island.The weather station provides measurement of air temperature (Deg. C.), humidity as relative percent, barometric pressure (milliBars or hPa), rainfall amount, intensity and duration, hail amount, intensity and duration (not common on coral reefs!) and wind speed and direction. The wind speed and direction and processed into scalar and vector (directional) based readings and presented as 10 and 30 minute averages to give mean values and maximum values. From these you can get the average wind conditions at either 10 minute or 30 minute periods as well as the gust or maximum wind conditions.The weather station is connected via an SDI-12 interface to a Campbell Scientific CR1000 logger which uses a RF411 radio to transmit the data, every 10 minutes, to the base station on Orpheus Island and then a Telstra nextG link is used to send the data back to AIMS.Identical weather stations are also on Heron Island (southern GBR), One Tree Island (near by) and Lizard Island (northern GBR). A light sensor is also located on the Island itself to give measures of PAR. The weather station is to provide on-reef weather conditions to allow the interaction with the atmosphere and the water to be understood. It is NOT set up as a meteorological grade station (for example it is too low to the water) but rather to give an indication of the atmospheric conditions at the surface of the water actually on the reef. If you need meteorological grade observations then use the data available for near by locations from www.bom.gov.au Power SupplyBattery Backed (1 x 33Ahr AGM with Solar Regulator), 4 x 5W Solar Panel Supply.Logger Settings - Pakbus Address - 150Logger Setup as router (isRouter = True)SDC7 comms board rate set at 34KSDC7 neighbours range: 1 - 180SDC7 Beacon: 3600Over-Reef RF Network - RF411 attached to the CSIO port of the loggerRadio Settings - Active Interface - Datalogger CSDCSDC Address 7Protocol: Pakbus awareRadio Net Address - 0Hop Sequence - 0Power mode - Retry level - Low

维萨拉WXT520（Vaisala WXT520）集成气象站安装于RP3号6米钢制杆体上，该杆体部署于大堡礁中部的奥费斯岛（Orpheus Island）。该传感器中继杆为搭载传感器以测量、监测奥费斯岛周边水域状况提供了平台。杆体采用900MHz扩频无线电实现实时通信，将数据回传至奥费斯岛上的基站。
该气象站可测量以下参数：气温（单位：摄氏度）、相对湿度百分比、大气压力（单位：毫巴或百帕）、降雨量、降雨强度与降雨时长、冰雹量、冰雹强度与冰雹时长（珊瑚礁区域罕有冰雹发生！）以及风速和风向。系统将采集到的风速与风向数据处理为标量与矢量（定向）读数，并以10分钟和30分钟为周期进行平均计算，得出平均风速与最大风速数值。通过该数据集，可获取10分钟或30分钟周期内的平均风况，以及阵风或最大风速情况。
该气象站通过SDI-12接口连接至坎贝尔科学（Campbell Scientific）CR1000数据采集器，该采集器搭载RF411无线电模块，每10分钟将数据回传至奥费斯岛基站，随后通过Telstra nextG链路将数据传输至AIMS。大堡礁南部的赫伦岛（Heron Island）、邻近的独树岛（One Tree Island）以及大堡礁北部的蜥蜴岛（Lizard Island）均部署了同款气象站。该岛上还搭载了光传感器，用于测量光合有效辐射（Photosynthetically Active Radiation，PAR）。
本气象站旨在提供礁体现场气象数据，以助力解析大气与水域之间的相互作用。该站点并非按照气象观测级标准搭建（例如安装高度距水面过近），仅用于反映礁体实际水面处的大气状况。若需符合气象观测级标准的观测数据，请从澳大利亚气象局官网（www.bom.gov.au）获取邻近区域的对应数据。
