Lizard Island Weather Station installed on Sensor Relay Pole 2

A Vaisala WXT520 integrated weather station has been installed on RP2, a 6m steel pole which has been installed within the lagoon of Lizard Island on the northern Great Barrier Reef. The sensor-relay pole provides a platform for the installation of sensors to measure and monitor water conditions within the lagoon of Lizard Island. The pole has real time communications using 900MHz spread spectrum radio back to a base station on Lizard 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 Lizard 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 Orpheus Island (central 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）一体化气象站部署于RP2号支架上，该支架为一根6米长的钢制杆体，安装于大堡礁北部蜥蜴岛的潟湖内。该传感器中继杆体为各类监测传感器的部署提供了承载平台，用于测量并监控蜥蜴岛潟湖内的水体环境参数。该杆体通过900MHz扩频无线电实现实时通信，将采集数据回传至蜥蜴岛上的基站。
该气象站可测量以下参数：空气温度（摄氏度）、相对湿度百分比、大气压力（毫巴或百帕）、降雨量、降雨强度与持续时长、冰雹量、冰雹强度与持续时长（珊瑚礁区域较为罕见！）以及风速与风向。风速与风向数据将被处理为标量与矢量（定向）读数，并以10分钟和30分钟的平均值形式输出，得到平均风速与极大风速。基于此类数据，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CR1000（Campbell Scientific CR1000）数据采集器，该采集器搭载RF411无线电模块，每10分钟将数据回传至蜥蜴岛基站；随后通过Telstra nextG链路将数据回传至AIMS。
赫伦岛（大堡礁南部）、邻近的独树岛以及奥菲斯岛（大堡礁中部）也部署了同款气象站。
该岛还部署了光传感器，用于测量光合有效辐射（Photosynthetically Active Radiation，PAR）。
本气象站旨在提供礁体原位的气象数据，以助力解析大气与水体间的相互作用机制。该站点并非按照气象级标准搭建（例如安装高度贴近水面），仅用于反映礁体水面处的实际大气状况。若需获取气象级观测数据，请从www.bom.gov.au调取附近区域的公开数据。
