Heron Island Weather Station installed on Sensor Relay Pole 5

A Vaisala WXT520 integrated weather station has been installed on RP5, a 6m steel pole, which has been installed within the lagoon of Heron Island as part of the sensor network infrastructure at Heron Island in the southern Great Barrier Reef off Gladstone, Australia.The sensor-relay pole provides a platform for the installation of sensors to measure and monitor water conditions within the lagoon of Heron Island. The pole has real time communications using 900MHz spread spectrum radio back to a base station on Heron 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 Heron Island and then a Telstra nextG link is used to send the data back to AIMS.Identical weather stations are also on One Tree Island (near by), Orpheus Island (central GBR) 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

澳大利亚格拉德斯通外南大堡礁赫伦岛的传感器网络基础设施中，一根6米长钢制杆RP5上安装了维萨拉（Vaisala）WXT520集成气象站，该杆部署于赫伦岛礁湖内。该传感中继杆为传感器安装提供了承载平台，用于测量与监测赫伦岛礁湖内的水体状况。该杆搭载900MHz扩频无线电实现实时通信，可将数据回传至赫伦岛上的基站。
该气象站可测量多项气象参数：空气温度（单位：摄氏度）、相对湿度百分比、大气压力（毫巴或百帕hPa）、降雨量（总量、强度与持续时长）、冰雹量、强度与持续时长（珊瑚礁区域较为罕见），以及风速与风向。系统会将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分钟的平均值形式输出平均风速与极大风速值，由此可获取10分钟或30分钟周期内的平均风况，以及阵风或极端风速情况。
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，该采集器通过RF411无线电每10分钟将数据传输至赫伦岛上的基站，随后通过Telstra nextG链路将数据回传至澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）。
单树岛（邻近区域）、奥菲斯岛（大堡礁中部）以及蜥蜴岛（大堡礁北部）也部署了同款气象站。赫伦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面气象条件数据，以助力理解大气与水体间的相互作用。该站点并非气象级观测站（例如安装高度过低），而是用于获取实际礁面水体表层的大气状况数据。若需气象级观测数据，请使用澳大利亚气象局（www.bom.gov.au）提供的邻近区域观测数据。
