Port Air Pressure – Barometer Calibration

The Bureau coordinates a network of around 70 foreign and Australian ships making up the Australian Voluntary Observing Fleet. These ships provide meteorological observations such as air pressure, temperature, humidity, sea surface temperature, wind speed and direction, and visual observations such as wave heights. The data from these ships is crucial to help inform forecasters about current conditions, and to develop coastal and high seas forecasts, and for longer-range computer climate modelling.

Commercial vessels operating within Australian waters routinely perform remote barometer calibration checks when in port. This page now enables ship crew to calibrate their marine barometers in real time and at regular intervals. The table below provides a link to the closest Automatic Weather Station for key ports around Australia. These weather stations update their barometric observations every half hour.
