Weather Station installed on RP3 at One Tree Island as part of the Facility for the Automated Intelligent Monitoring of Marine Systems - FAIMMS

A Vaisala WXT520 integrated weather station has been installed on RP3, a 6m steel pole, which has been installed within a small bommie in Third Lagoon on One Tree Island as part of the sensor network infrastructure at One Tree Island in the southern Great Barrier Reef off Gladstone, Australia. \n\nThe sensor-relay pole provides a platform for the installation of sensors to measure and monitor water conditions within the lagoon of One Tree Island. The pole has real time communications using 900MHz spread spectrum radio back to a base station on One Tree Island. \n\nThe 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. \n\nThe 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 One Tree Island and then a Telstra nextG link is used to send the data back to AIMS.\n\nIdentical weather stations are also on Heron Island (near by), Orpheus Island (central GBR) and Lizard Island (northen GBR). A light sensor is also located on the island itself to give measures of PAR.

维萨拉WXT520集成气象站（Vaisala WXT520）已部署于RP3号6米钢制杆上，该杆安装于澳大利亚格拉德斯通外海南部大堡礁（Great Barrier Reef）区域单树岛（One Tree Island）第三潟湖（Third Lagoon）内的一处小型珊瑚丘中，作为单树岛传感器网络基础设施的组成部分。

该传感器中继杆可为部署传感器提供搭载平台，用于测量并监测单树岛潟湖内的水体状况。该杆搭载900MHz扩频无线电，可实现实时通信，将数据回传至单树岛基站。

该气象站可监测多项气象参数：空气温度（摄氏度）、相对湿度百分比、气压（毫巴或百帕hPa）、降雨量、降雨强度与历时、冰雹量、冰雹强度与历时（在珊瑚礁区域较为罕见！），以及风速与风向。风速与风向经处理后生成标量与矢量（定向）读数，并以10分钟和30分钟平均值的形式呈现，以获取平均值与极大值。由此可获取10分钟或30分钟时段的平均风况，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，后者搭载RF411无线电模块，每10分钟将数据传输至单树岛基站；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）。

附近的赫伦岛（Heron Island）、大堡礁中部的奥菲斯岛（Orpheus Island）以及大堡礁北部的蜥蜴岛（Lizard Island）也部署了同款气象站。该岛礁还部署了光照传感器，用于测量光合有效辐射（Photosynthetically Active Radiation, PAR）。
