This week, with the help of many on station, the 10 metre tilting mast holding the anemometer was swapped for an eight metre tilting mast on top of a ‘pregnant base’. This is a setup that the Bureau of Meteorology often uses in remote locations.
Our Automated Weather Station (AWS), the computer that records all the measurements from our remote sensors, lives inside the Meteorology office. In remote weather yards the AWS is situated inside the pregnant base, and sends weather data back to the central message system.
There are a lot of uncertainties in the upcoming station modernisation — where the new Bureau office will be, whether our yard will move, and most importantly whether modernisation operations will impact our long term readings.
Establishing the new mast is the first step in a process to ensure any impacts are recognised. The next step will be to install a new instrument screen alongside the anemometer mast to hold comparison instrumentation. The data collected will be recorded by a new AWS that will be installed within the pregnant base.
Not only will the new AWS record data to compare with that already collected, it will also be used when the Met office on Macca is transitioned to its new location.
