One Tree Island Weather Station installed on Sensor Relay Pole 3

Brief description

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. The 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. 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 One Tree Island and then a Telstra nextG link is used to send the data back to AIMS.Identical 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.
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.
